Statements 1 and 2 are correct; statement 3 is incorrect.

- 1 & 2: mRNA (messenger RNA) carries the genetic instructions for making proteins from DNA and transports those instructions from the nucleus to ribosomes, where protein synthesis occurs. Other RNAs (tRNA, rRNA) also play essential roles in translation (tRNA brings amino acids; rRNA is part of the ribosome).
- 3: RNA is not the structural unit of DNA. DNA is made of deoxyribonucleotides (with deoxyribose and thymine); RNA is a separate type of nucleic acid (ribose and uracil).
