Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA. During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs. RNA polymerase moves from the 3 'end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA. Therefore, D. Nucleic acids attach to the bases in the DNA.

Answer:
D. A base substitution in gametes during meiosis
Explanation:
I would say that active transport is the answer because it's from LOW concentration to HIGH concentrations, so it's going against the concentration gradients.
Answer:
Yes
Explanation:
Just like a building which has different types of openings, so does a cell. These openings also have many different functions just like an opening in a building. A window is an opening which has a function just like a cell. Different openings have different functions.
