Answer:E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
Explanation:
Chargaff's rules state that in a given DNA molecule the percentage of Adenine %A is approximately equals the percentage of Thymine %T and the percentage of Guanine %G is approximately equals the percentage of Cytosine %C.
Answer is
E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
Answer:
1) Founder effect and genetic drift: Small colonizing population did not represent the original gene pool of the source population and was more likely to undergo genetic drift.
2) Natural selection
Explanation:
Evolution of the population of the finches with larger beaks might have occurred due to one of the following mechanisms:
a) Founder effect and genetic drift: Since the size of the colonizing population was small, it did not carry all the genes and their alleles present in the gene pool of the original population. The small population size made it more likely to evolve by any chance event.
b) Natural selection: The availability of different food types in the new habitat led to the natural selection of the larger beaks as the finches with larger beaks might have been able to better exploit the available food resources.

<span>Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Meanwhile, mRNA is comparable to a copy from a reference book because it carries the same information as DNA but is not used for long-term storage and can freely exit the nucleus. Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template.</span>
