Why is Replication important to YOU? A. To make your proteins.
C. To destroy old cells.
B. To help you make more cells and grow.
D. To change your genetic code.

B to make more cells and grow.

Explanation:

This is because the primary purpose of DNA replication is to repair and replace old and damaged cells. If something goes wrong this can result in bad cell growths like cancer. DNA replication is also used in reproduction.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
