Proteins are made up of polypeptides.
This is a very simple process where MRNA is produced from DNA.
A DNA molecule is split into single strands by DNA helicase.
Free bases are then joined together by RNA polymerase in order to form a single strand which is complimentary to the DNA strand.
This single strand is called pre-MRNA and contains many introns which don't code for any amino acids.
This is where all the introns are taken out of pre-MRNA in order to form MRNA which is completely formed of exons.
A ribosome attaches to the start codon on the…
