Explanation / Answer
1.The size of a genome
c.Is the term used to describe all of the DNA of an organism
Size of a genome is the total amount of DNA present within one copy of a single genome. It is measured in terms of mass in picograms. Organisms complexity is not directly proportional to its genome size.
2. When looking at essential proteins that are conserved amongst different species
b. The only thing to look at is a protein sequence
The term conserved proteins refer to the aminoacid sequence of a protein is conserved, that means the protein is found in multiple species that are distantly related.
3. Molecular Evolution
a.Looks at the sequences of DNA and RNA
c.Uses molecular evolution to explain the molecular basis of biological diversity
Molecular Evolution is the process of change in the sequence of DNA, RNA and proteins across generations. Molecular Evolution of proteins is studied by comparing the sequence and structure of proteins from many organisms.
