<span>S phase is the duplication of the cells genetic information, if this did not occur, when the cell divides into two cells, there would be no copy of this genetic information given to 1 out of the 2 cells.

Claim stating what the translated sequence from the DNA sequence is
Stella [2.4K]

First you need to convert the template strand (what you have) to the coding strand.

So using the following guide convert the given letters:

A->T

T->A

G->C

C->G

This will now encode your strand as:

CCTGTAAAAGTGGCA

Break these into three letter chunks:

CCT GTA AAA GTG GCA

Your teacher should either give you a guide or tell you which ones to memorize, but you could also use the following chart to figure out which amino acids will be synthesized:

Use the chart underneath The Genetic Code(DNA) to figure out what matches where.

You will then get the following:

1. Proline (cct)

2. Valine (gta)

3. Lysine (aaa)

4. Valine (gtg)

5. Alanine (gca)

Also remember that if you see a T in your original strand it could also be interpreted as a U. You can always check your answers using this handy online app: http://www.geneseo.edu/~eshamb/php/dna.php

To increase the absorption of nonheme iron in beans, you can eat a food with _____ alongside the beans
choli [55]

To increase the absorption of nonheme iron in beans, you can eat a portion of food with vitamin C alongside the beans.

<h3>What are vitamins?</h3>

Vitamins are certain micronutrients that may help to absorb other nutrients (e.g., minerals) in the body.

Vitamins are micronutrients that can be classified as fat-soluble vitamins and water (hydrophilic) soluble vitamins.

Vitamin C is required for the formation of blood vessels, muscle and cartilages in the body.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter
arsen [322]

Answer:

The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.

Explanation:

As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

The nucleoside analogue acyclovir, which is used to treat herpes simplex virus (HSV) infections, lacks a 3′ hydroxyl group (–OH)
Dima020 [189]

Answer:

There won't be any functional viral DNA synthesis

Explanation:

First of all, you must consider that the HSV has a double-stranded, linear DNA genome. Furthermore, the DNA skeleton is made of the 5'-3' phosphodiester bond. In other words, the 5-phosphat of a nucleotide will bond the 3' OH of the Deoxyribose (see image).

Therefore, if you add a molecule which lacks the 3' OH, such as acyclovir, and has a similar chemical structure to a regular nucleotide, the DNA polimerase will be able to add acyclovir to the main backbone of the viral genome. All in all, you'd be ''cheating'' the DNA pol.

Hence, wherever acyclovir was integrated, there won't be any chance to form a 5'-3' phosphodiester bond. The protomolecule will not be stable and will soon be degradated.
