Question

short answer: what are the two main stages of gene expression? *
your answer

what is the role of rrna in protein synthesis? *
copies dna
delivers amino acids
reads the code at the ribosome
breaks down proteins

which rna molecule carries amino acids to the ribosome? *
mrna
rrna
trna
dna

Explanation:

1. Gene expression has two main stages: transcription and translation. Transcription is the synthesis of RNA from a DNA template, and translation is the synthesis of proteins using the information in mRNA.
2. rRNA is a component of ribosomes and helps in reading the code at the ribosome during protein - synthesis. It forms the structural and functional part of the ribosome where the translation process occurs.
3. tRNA (transfer RNA) is responsible for carrying amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon that pairs with a codon on the mRNA and carries the corresponding amino acid.

Answer:

1. Transcription and translation
2. C. Reads the code at the ribosome
3. C. tRNA
