How to Read the RNAm to Make Proteins After the Transcribing DNA as RNAm
It exists from the nucleus to the cytoplasm. There, ribosomes are waiting for the RNAm, and the two subunits look for the first codon AUG. The RNAm is read by triplets. All the possible combinations of codons and its corresponding amino acids are called genetic code. Mutation is the alteration of the DNA sequence that can be transmitted to the offspring (if it occurs in gametes).
