Question

evidence for evolution: molecular evidence
when we look inside cells, we find molecular evidence for evolution. every living organism contains dna, which is the heritable genetic code of life. all dna is constructed of the same four nitrogenous bases, held together by a sugar - phosphate backbone. the presence of dna in all living organisms suggests we all evolved from a single common ancestor. another homology is found in the synthesis of proteins. this process requires rna to be produced from dna in all organisms, from turtles to bacteria. and the same amino acids are coded for by the same dna triplets.
we can compare the genes found in different species to work out how closely related they are. sequencing of the human genome (the entire genetic material found in a human) was completed in 2003. since then many other species have had their genomes sequenced. comparisons reveals that the majority of our dna is shared with other species.
name the four nitrogenous bases found in the dna of all living organisms

Explanation:

In DNA, the four nitrogen - containing bases are adenine (A), thymine (T), guanine (G), and cytosine (C). These bases form the genetic code and pair in specific ways (A with T, G with C) in the double - helix structure of DNA.

Answer:

Adenine (A), Thymine (T), Guanine (G), Cytosine (C)
