A number of antiviral drugs act by preventing viral DNA synthesis. These drugs are typically chemically similar to nucleotides with a modification. For example, the drug may contain all relevant components of a nucleotide, including a proper purine or pyrimidine base, but lack the 3' OH group. How would this modification allow this drug to prevent viral DNA synthesis
This modification allows the drug to prevent viral DNA synthesis by different mechanisms as an enzyme DNA polymerase follows.
What do you mean by DNA synthesis?DNA synthesis may be defined as the biological process by which a deoxyribonucleic acid (DNA) molecule is created.
The enzyme DNA polymerase adds some of the nucleotide bases to the strand that contains 3'-OH at the end. But when the end part of the strand lacks the 3' OH group, it inhibits the process of DNA transcription.
Therefore, this modification allows the drug to prevent viral DNA synthesis by different mechanisms as an enzyme DNA polymerase follows.

any other animal, why can't they do anything about overpopulation?
Answer:
Explanation:
What about war? Why can't we do anything about war?
How about our needs and wants beyond shelter and food?
Of all the things plaguing the world, I think over population is one of the things we can do something about. You are right. But needs and wants play a huge role in why we can't seem to do anything right.
Of course on thinking it over, we have problems that have their roots in overpopulation like pollution.

Immunization with the childhood DPT (diphtheria, pertussis, and tetanus) vaccine protects against subsequent exposure to tetanus by Group of answer choices generating tetanus-specific memory B cells. producing life-spanning antitetanus IgE antibodies. stimulating quick inflammation upon future exposure. preloading antigen-presenting cells. stopping isotype switching of B cells from IgM to IgA.
Answer:
generating tetanus-specific memory B cells
Explanation:
Memory B cells are cells of the immune system that produce antibodies against specific antigens present in pathogenic organisms. The B lymphocyte cells produce clonal memory B cells after the first exposure to the antigen, a process known as clonal selection. Subsequently, memory B cells that circulate in the bloodstream trigger a rapid secondary immune response (after a second exposure to the antigen) by producing antibodies against specific antigens that activated their parent B cell. Moreover, the DPT vaccine includes purified tetanus toxins (i.e., target antigens) that induce clonal expansion in specific B cells, thereby generating a population of memory B cells that produce specific antibodies rapidly in secondary immune responses.

What is freezing?The process by which something changes from liquid to solid as the temperature drops is known as freezing. Water basically freezes at 0 degrees Celsius.
The process of changing a substance from a liquid to a solid is known as freezing. When a liquid's molecules slow down enough, their attractions cause them to arrange themselves into fixed positions as a solid.
The average energy of the molecules in a liquid decreases as it cools. At some point, the amount of heat removed is great enough that the molecules' attractive forces draw them close together, and the liquid freezes to a solid.
The particles in a liquid eventually stop moving and settle into a stable arrangement, forming a solid.
Thus, the correct option is B.

Which of the following describes a portion of the water cycle that is not driven by
gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds
The correct answer is A. Evaporation of ocean water to form clouds.
Explanation
The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.

Give them a prescription medication, then continue training session D. Give them Advil, then continue training session
Answer:
A .recommended they drink water then stop training session
Explanation:
Because the trainer can't just give out prescription medication. They don't know if the person has allergies and it can make the clients headache worse.
A. Recommend they drink water, then stop the training session
First thing first, drug abuse is not an option. Drug abuse includes self medication or taking drugs not prescribed by a medical practitioner. As a fitness trainer, ones job is not to prescribe drugs.
According to this question, if a client is experiencing headaches during a training session, the best alternative for the trainer is to recommend taking water to calm the client down, then put an hold to the training. The trainer is not qualified to prescribe any drug whatsoever.
Therefore, the trainer should recommend that a client with headache drink water, then stop the training session.
Which statement regarding DNA packing in eukaryotes is false?
A Tight DNA packing tends to promote gene expression
B) Euchromatin can be highly expressed
с
none of the answers are false
D
A nucleosome consists of DNA wound around a core of 8 histone
molecules.
E Highly compacted chromatin is generally not expressed at all.
Answer:
The correct answer is - A. Tight DNA packing tends to promote gene expression.
Explanation:
Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.
DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .
DNA packing decreases its transcription and hence no expression.

Enhancerless GFP reporter constructs used in research conducted in mice contain a generic mouse gene promoter (TATA box) followed by a transcription start site and then a GFP gene cDNA. When such enhancerless reporter gene constructs are integrated into random locations in the mouse genome, about 10% of the time, high levels of tissue-specific GFP expression are detected, even though the reporter gene construct itself has no enhancer. How is this possible
Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
