Answer:

A. DNA polymerase

Explanation:

DNA polymerases (I,II,III) proofread the DNA, which helps to catch errors. Errors can be fatal to expression, creating misformed proteins or unclear information, so this is necessary.

Fun facts - the coronavirus is a retrovirus, so it doesn't proofread. That makes it much harder to find a vaccine, because it can generate new strains by the very fact of not proofreading.

Yuri [45]
In normal situations:
-The thin ascending limb is of the loop of henle is impermeable to water. But, is permeable to ions (sodium, chloride) that cross by diffusion.
-Urine osmolality should be 300-900 mOsm/kg of water.

In this case, if the <span>ascending limb of the loop of henle is permeable to water is the same as saying the loop isn't doing it's job of </span>creating a concentration gradient.
Because of that, The process  of reabsorption of water and creation of a concentrated urine is not correctly happening.

The answer is E<span>. minimum 300 / maximum 300
</span>
The loop of Henle receives isotonic (300 mOsm/L) fluid, from the <span>proximal convoluted tubule, and since it's not working th way it should it won't change those values. </span>

egoroff_w [7]

Answer: DNA is a polymer of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base

Explanation:

Every molecule in the human body are formed by the chains of particular substances. These components are arranged orderly as linked chains to give the structure called DNA.

The components include nucleotides—this is also considered the chemical substance in the human body which helps in the formation.

In this formation of chains, nitrogenous bases will also be linked to form a polymer of DNA.
