Plea answer A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample

A 20% cytosine, 20% thymine, 20% guanine

B 30% cytosine, 209. thymine, 30% guanine

C 10% cytosine, 30% thymine. 40% guanine

D 30% cytosine, 30% thymine, 20% guanine

Explanation:

According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

i think the miocene epoch spans the time from 23 million to 12 million years ago.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
