In eukaryotes, DNA is found in the cytoplasm of the cell.

RNA is the nucleic acid that helps build proteins.

DNA is the nucleic acid that carries genetic information.

The structure of proteins is determined by DNA.

A chromosome is made of RNA.

Answer 1

True statements:
- RNA is the nucleic acid that helps build proteins. (mRNA, rRNA and tRNA are directly involved in protein synthesis.)
- DNA is the nucleic acid that carries genetic information. (Genes are encoded in DNA.)
- The structure of proteins is determined by DNA. (DNA sequence specifies amino acid sequence, which determines protein structure.)

False statements:
- In eukaryotes, DNA is found in the cytoplasm of the cell. (In eukaryotes most DNA is in the nucleus; small amounts are in organelles like mitochondria/chloroplasts.)
- A chromosome is made of RNA. (Chromosomes are composed of DNA packaged with proteins such as histones.)
