In normal cells the amino acid phenylalanine attaches to tRNAs with the anticodon AAA. The enzyme aminoacyl-tRNA synthetase catalyzes the reaction that attaches the amino acid to the correct tRNA. Assume that a mutation occurs in the aminoacyl-tRNA synthetase enzyme and causes it to attach lysine instead of phenylalanine to tRNAs with the anticodon AAA. What will be the consequence of this mutation for the translation process
Answers
Answer:
Aminoacyl-tRNA bond is hydrolyzed.
Explanation:
The consequence of this mutation for the translation process is the hydrolysis of aminoacyl tRNA bond occur. If the incorrect amino acid is attached to other molecule as a result of this reaction, the aminoacyl-tRNA bond is hydrolyzed. This incorrect binding of amino acid occur because of mutation in the aminoacyl-tRNA synthetase enzyme that leads to its hydrolysis.
QUESTION 1
Which of the following statements are true of arteries and veins? (Read carefully and select all of the correct statements.)
A. Venous anastomoses ensure that oxygenated blood will get to tissues.
B. The endothelium of both arteries and veins contributes to the prevention of abnormal clotting.
C. The smooth muscle layer of veins is thicker than that of arteries because veins are farther from the heart.
OD. Only veins have valves, which keep the blood moving between heartbeats.
E. The fibrous connective tissue layer of arteries is relatively thin because the blood is moving fast.
OF Arterial anastomoses ensure that blood will be able to return to the heart.
Answers
Answer: B, D
Explanation:
Is this a Med School K Question? The endothelial lining of blood vessels have many functions, including, preventing clotting. Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.

Answer: The odd one one is diphtheria
Explanation:
There are very minute living organisms that are able to cause different diseases to human which are found in our environment. These are known are microorganisms. They include:
--> viruses
--> bacteria
--> fungi
These microorganisms are able to establish an INFECTION in its human host when it's able fight and overcome the body defence mechanism of the host.
Diphtheria is the odd one because it's an infection which is caused by BACTERIA organism while other options while includes measles, mumps and polio are caused by VIRUS microorganisms.
BACTERIA are the larger microorganisms with a very simple cell structure where the nucleus is not enclosed within a membrane. While VIRUS are the simplest and smallest microorganisms which do not have a cell structure.
Diphtheria is an infection caused by the bacteria microorganism known as the Corynebacterium diphtheriae. These bacteria are able to produce toxins which is its virulent factor that are poisonous to its host.
Measles is an infection caused by paramyxovirus.
Mumps is an infection caused by mumps virus
Polio is an infection caused by picornavirus.
Therefore, Diphtheria infection is the odd one out.

The stems of bamboo, a tropical grass, can grow at the phenomenal rate of 0.3 m/day under optimal conditions. Given that the stems are composed almost entirely of cellulose fibers oriented in the direction of growth, calculate the number of sugar residues per second that must be added enzymatically to growing cellulose chains to account for the growth rate. Each D-glucose unit contributes ~0.5 nm to the length of a cellulose molecule.
Answers
Answer:
Approximately 6944 glucose residues are added enzymatically per second
Explanation:
Cellulose is the main structural polysaccharides in plants. It is composed of unbranched glucose monomer units linked to each other by beta 1-4 glycosidic bonds.
The cell wall and stem of plants cells are composed of cellulose fibers. They provide rigidity and support to the plant.
In the given bamboo plant, the enzymatic addition of glucose units to the growing cellulose fiber chains results in the phenomenal growth rate of the bamboo stem.
Since each glucose unit contributes ~0.5 nm to the length of a cellulose molecule, number of glucose units required for daily growth is calculated as follows:
0.5 nm = 10⁻⁹
0.3 m/0.5 x 10⁻⁹ m = 600000000 units of glucose per day
Number of seconds in a day = 24 * 60 * 60 = 86400 seconds
Number of glucose residues added per second = 600000000/86400
Number of glucose residues added per second = 6944.4 glucose molecules per second
Therefore, approximately 6944 glucose residues are added per second

What regulates breathing rate and how does the body sense when to breath?
Answers
Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
How is dopamine involved in drug addiction?

3) drugs decrease dopamine levels in the brain.
4) drugs increase the level of dopamine in the brain
Answer and I will give you brainiliest
Answers
Answer:
The correct answer is - option D.
Explanation:
When an individual takes drugs such as heroin, nicotine, cocaine and methamphetamine increases or promotes the neurochemical reaction that increases the amount of dopamine which is a primary factor in addiction that is secreted by neurons in the brain's reward center.
Higher dopamine levels lead to pleasure in the mind of an addict and it makes people forget the pain or stress and gives immense pleasure.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
Answers
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

Given a DNA sequence of ACG, what would be the corresponding RNA sequence? Once you determine the RNA sequence, what would be the corresponding amino acid for the RNA codon? Would a change in one nucleotide of the DNA alter the corresponding amino acid? Explain.
Answers
Answer:
- RNA sequence: UGC
- Amino acid sequence: Cysteine
- Yes, a change in nucleotide will alter the amino acid.
Explanation:
According to this question, a DNA sequence was given as follows: ACG. The process of transcription will produce a RNA sequence from this DNA sequence using complementary base pairing i.e. A-U, G-C etc. Based on this, the mRNA sequence that will result of the DNA sequence above is UGC.
The resulting mRNA transcript is a codon (three nucleotides) that will be used in the process of translation to yield an amino acid. The mRNA sequence: UGC codes for amino acid Cysteine.
- A change in one nucleotide of the DNA will alter the corresponding amino acid because DNA sequence in a particular reading frame is responsible for the production of amino acid. Hence, a slight change in nucleotide might change the reading frame of the sequence and hence give rise to a different amino acid.

Answers
Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.
