Differences in dna and rna |
1 dna has deoxyribse rna has ribose 2 dna is double stranded rna is single stranded 3 dna has thymine rna has uracil |
|
|
3 types of rna |
mRNA - messenger rna tRNA - transfer rna Rrna - ribosomal rna |
|
|
Function is mRNA |
Takes the message from the dna in the nucleus to the ribosomes |
|
|
Function of tRNA |
Reads the message and gathers the right amino acids |
|
|
Function of rRNA |
Bonds the mRNA and tRNA to the ribosome |
