Reactions such as oxidation or deamination can alter dna bases. after replication, these changes may result in point mutations.

for example, if cytosine undergoes deamination to yield uracil, the original c:g base pair may be altered to t:a. (c base pairs with g, but u pairs with
a. uracil is recognized and \"corrected\" to t, leading to the t:a pair.) two dna modifications are shown below. label each change as an oxidation or a deamination, place the appropriate molecule in each reaction, and determine the resuting point mutation (nucleotide substitution).

Answer:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder the DNA molecule consists of two strands that wind around each other like a twisted ladder. Attached to each sugar is one of four bases--adenine (aka A), cytosine (aka C), guanine (aka G), or thymine (aka T).

Jet001 [13]

Explanation:

This question requires more information for a complete answer. The first trophic level of a food chain or web is reserved for plants and other photosynthetic organisms that captures solar energy from the sun and converts it to chemical energy. The second trophic level is reserved for herbivores or primary consumers. The third trophic level or secondary consumers are carnivores or predators.

Decomposers are not usually drawn or represented in a food web or chain but they do play a vital role. Decomposers break down dead and decaying organisms and return these unused nutrients to the soil for producers to use.
