When DNA is replicated, the two strands are first separated through _________; each strand then becomes a _________ against which two new strands are made.

Answers

Answer 1

Answer:

Answered below

Explanation:

Deoxyribonucleic acid, DNA, replication is the process whereby DNA makes a copy of itself and it occurs during cell division.

When DNA is replicated, the two strands are first separated through unzipping at the origin of the replication fork. This is catalysed by the enzyme helicase. Helicase breaks down the hydrogen bonds which hold the complementary base pairs of DNA together.

Each strand of DNA to then becomes a template against which two new strands are made. One of the strands is called the leading strand and the other is called the lagging strand. Both are oriented in opposite directions.

D

Explanation:

I did it on my own soci know it's the answer

In the context of interphase, the S phase is the specific part where DNA replication occurs, contributing to the overall process of cell division and ensuring the transmission of genetic material to new cells and the correct option is option D.

Interphase is the longest phase of the cell cycle, and it is divided into three main stages: G1 phase, S phase, and G2 phase. Among these stages, the S phase is specifically responsible for DNA replication. It is during the S phase that the cell's DNA is duplicated in order to prepare for cell division.

During the S phase, the DNA helix unwinds, and the two strands separate. Enzymes and proteins then work together to synthesize new complementary strands for each of the separated DNA strands. As a result, two identical copies of the DNA molecule are produced.

The S phase plays a crucial role in maintaining the genetic integrity of the cell. By accurately duplicating the DNA, the cell ensures that each daughter cell formed during cell division receives an identical set of genetic information. This is vital for the proper functioning and development of organisms.

Thus, the ideal selection is option D.

Answers

Answer:

Deep Brain Stimulation (DBS)

Depression, Uncoordinated body movements such as in Parkinson's disease

Explanation:

Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.

This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.

The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.

This includes deforestation because trees are usually cut to build houses and other human structures. Indeed, most threes and plants are removed for human construction. This also implies a loss of natural resources that include a wide variety of plants, animals, and even water as nearby bodies of water might be polluted. Besides, this general pollution increases in the area this includes noise pollution, water pollution and air pollution that result from human activities. Thus, all are possible consequences of urban sprawl; therefore, the correct answer is none of the above.

Which type of mutation occurs only in gametes?
germline mutation

somatic mutation

point mutation

frameshift mutation

Answers

Answer:

Germline mutation

Explanation:

A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.

The type of mutation that occurs in gametes only is : ( A ) Germline mutation

Germline mutation is a type of mutation that occurs in the gametocytes ( male and female ) and is passed( inherited ) on to the offspring ( next generation ). while mutations occurring in somatic cells are not passed on to the next generation .

Germline mutation is induced by either endogenous factors or exogenous factors and this is because Germline mutations can occur before fertilization or after fertilization.

Hence we can conclude that the type of mutation that occurs in gametes only is Germline mutation.

Slowing Down Global Warming As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change

Answers

Answer:

The increasing level of all the facilities like transportation, production, human waste, and developing new spaces for human beings among others are some of the most essential features of climate change. Thus, the demand for novel products, space, and facilities would also enhance with the increase in the population. This signifies that with the enhancement in the facilities, the environment would get influenced, which would eventually influence the climate.  

There would be more emission of carbon dioxide and thus more pollution would develop with the increase in the population of human beings, this further would add up in climate change and global warming. Thus, there is a need in the control of the human population, however, technology is also important in helping humans to sustain a better life. This technology should be advanced and well-equipped so that our climate and environment exhibits no deleterious effects.  

Novel technologies like the use of renewable energy, green building, prudent application of resources, and others would also assist the humans in sustaining the environment.

B. Progressively decrease over a period of time
C. Remain the same
D. Acute decrease over a period of time

Answers

Answer:

A. Progressively increase over a period to time

Explanation:

The law of overcompensation states that the environment compensates for any factor by twice the amount and the overload theory states that challenges should be increased while working on a certain task to improve the results.

The laws allow for the following:

Option A. Progressively increase over some time.

The laws can be explained as:

In fitness and sports, the laws of overload and overcompensation are widely used.

The overload principle says that the intensity and exercise duration should be increased gradually to see an improvement in endurance, strength and muscles.

According to the overcompensation theory, the body recovers from any injury or harm the body does not quit there and will be stronger compared to before.

Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable autosomal dominant genetic disease, in an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible not all offspring will receive the abnormal allele from an affected heterozygous parent.
Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease.
Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease.
Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.

Answers

Answer:

As it is given that Mark's paternal grandmother and grandfather does not carry the disease. The symbols on the right side of the Punnett represent Mark's paternal family. If both his paternal grandparents are unaffected then his father and paternal aunt are also not affected by the disease.

His maternal grandfather is affected as mentioned and also his maternal aunts are affected. Mark's mother is unaffected as she does not have the disease-causing alleles determined by genetic testing.

Both of the marks parents are unaffected which indicates that marks also do not carry the allele of the disease.

Huntington's disease is an autosomal dominant disorder in which the presence of even one dominant allele can cause the disorder.

The autosomal disorder can not skip a generation, have to be present in every generation.

Condition Given:

Affected Member: Mark's Maternal grandfather and Maternal aunts.

Normal: Mark's Maternal grandmother and Mark's Mother.

As MArk's Maternal Grandfather is affected then his genotype must be Aa because Mark's Maternal grandmother is unaffected (aa), this is the only condition where Mark's mother will be normal.

As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change

Answers

Answer:

See the answer below

Explanation:

The relationship between climate change and increased population of humans is a direct one. As the population of humans increases, their activities leading to the release of greenhouse gases such as CO2 and methane also increases. The greenhouse gases are primarily responsible for the warming of the earth.

As more and more greenhouse gases are released into the atmosphere, more radiation from the sun is trapped in the atmosphere and the earth receives more warmth. This extra heat received leads to increase in the global temperature, a phenomenon known as global warming. As the average global temperature increases, climate becomes more erratic and unpredictable.

The greenhouse gases-related activities of humans that are bound to increase with the increase in population include deforestation, fossil fuel burning, industrialization, etc.

A circular double-stranded DNA molecule contains 4200 base pairs. In solution, DNA is in a B-form helix, with about 10.5 base pairs/turn. The DNA has 12 superhelical turns. What is its superhelix density

Answers

Answer:

The correct answer is - 3 × 10⁻²

Explanation:

first find LKo = length of BDNA/ 10.5 bp/turn

= 4200/10.5

= 400

now calculate Δ LK= LK - LKo

ΔLK = 412-400

ΔLK = 12

now, superhelix density  = ΔLK/LKo

⇒ 12/400 = 0.03

= 3×10⁻²

Thus, the correct answer is - 3 × 10⁻²
