Answer:
In RNA, <em>thymine</em> is <u>replaced</u> with Uracil.
Explanation:
Genetic material (DNA and RNA) is made up of nucleotides. These are Adenine, Thymine, Guanine, Cytosine, and Uracil. Three of them (Adenine, Cytosine, and Guanine) are present in both types of genetic material, i.e. DNA and RNA. However, in DNA Thymine is present whereas in RNA, Uracil replaces Thymine. They are similar in structure except that Thymine has additional methyl group.
Two species have homologous structures. What do these homologous structures show about the evolutionary relationship between the two species? (3 points) The homologous structures show that the two species followed up the evolutionarypath up to the structure. They may have branched off right after that trait.
