Question

a molecule found in dna and rna that encodes genetic information in cells.
choose an answer
1 phosphate
2 nitrogenous base
3 nucleic acid
4 amino acid

Explanation:

• Phosphate is part of the backbone of DNA and RNA but does not encode genetic information.
• Nitrogenous bases (like G, A, C, T in DNA) are the specific molecules that encode genetic information. In DNA, the sequence of these bases forms the genetic code. RNA also has nitrogenous bases (with Uracil replacing Thymine in some cases) that carry genetic information.
• Nucleic acid (like DNA or RNA) is the overall molecule type, but the specific encoding part is the nitrogenous base within it.
• Amino acids are building blocks of proteins, not the encoders of genetic information in DNA/RNA.

Answer:

1. Nitrogenous base
