Answer

To identify a nucleotide, I would place a clear box around any of the components that consist of a phosphate group, a five-carbon sugar (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine) in the provided diagram.

Step 2

Outline the main steps of DNA replication

Answer

Initiation: DNA replication begins at specific locations called origins of replication, where the DNA unwinds and separates into two single strands.
Elongation: DNA polymerase synthesizes new strands by adding nucleotides complementary to the template strands in the 5' to 3' direction.
Termination: Replication ends when the entire molecule has been copied. The newly synthesized DNA strands wind together, reforming the double helix structure.
