What are the three types of RNA and what does each do? |
|
Definition
mRNA carries info from DNA to cytoplasm
tRNA brings in the amino acids to build the protein
rRNA acts like an enzyme to position the mRNA and tRNA so the protein forms |

Term
How can RNA be translated into proteins? |
|
Definition
mRNA codes for amino acids using three letter groups (codons)
rRNA positions the molecules the right way so the proteins can get built
tRNA carries in the correct amino acids to build the protein by matching three bases (anticodons) to the codon |
