Question

double stranded molecule, can be found inside of the nucleus. t pairs with a, c pairs with g.
amino acid
rna
dna
protein

Explanation:

The description mentions a double - stranded molecule in the nucleus with base - pairing (T - A, C - G). DNA is double - stranded, located in the nucleus, and has this base - pairing. Amino acids are the building blocks of proteins, RNA is usually single - stranded (except some forms), and proteins are made of amino acids. So the correct option should be the one labeled DNA.

Answer:

DNA (the third option from the top, labeled "DNA")
