Gene mutations can be caused by many things. These mutations are biologically important because they (1) occur at a regular rate and therefore can be controlled (2) can be passed to the offspring if they occur in any cell of the body (3) are always harmful and therefore help to eliminate weak traits (4) can result in a new variety of gene combinations in the species

2) can be passed to the offspring if they occur in any cell of the body

(4) can result in a new variety of gene combinations in the species

Explanation:

Mutations are sudden heritable changes that occurs in the genome of an organism. Mutations occurs in rare cases in about 1 of thousands or 1 of hundred thousands.

Because mutations affects gene they can be inherited, some can be deleterious leading to death, some with adverse effect leading to deformity while some can be beneficial leading to new variety and gene combinations in some species of organisms.

Mutations are usually sudden, they are spontaneous reactions that occur unexpectedly.

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

im not in connections yet but i might can you some questions. what grade are you in?
