A macromolecule is a large molecule containing many atoms. The four type are carbohydrates, lipids, proteins, and nucleus acids.
Can you please take a picture of the question. Because I don’t understand it in this format
It is called a nucleus. It's what determines what type of metal, gas, or whatever on the table.
The correct answer is b. no additional nucleotides would be added to a growing strand containing that nucleotide.

Nucleotides without a 3’hydroxy group are called dideoxynucleotides (ddNTD). Dideoxynucleotides are inhibitors of DNA polymerase because after being added in PCR reaction no further nucleotides can be added as no phosphodiester bond can be created (usually 3' hydroxyl group of the previous nucleotide attaches to 5' phosphate of the current nucleotide).</span>
