You can find the following nucleotide in mRNA and tRNA, but not DNA

• Adenine

• Uracil

• Cytosine

• Guanine

What is the role of mRNA in protein synthesis?

• 1. mRNA is responsible for the replication of DNA in the nucleus.

• 1. mRNA’s role is to transport amino acids to the ribosome.

• 1. mRNA carries the genetic code from DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.

• mRNA acts as an enzyme to catalyze biochemical reactions
