a group of three mRNA nucleotides is called a codon, which meets complementary triplet of tRNA nucleotides, called an anticodon, in the ribosomes. Carboxyl(also called acid), amino, and the radical which is what is changed to make an amino acid unique.
DNA double helix unwinds, and the bases on the two. strands are exposed. RNA nucleotides. (ribonucleotides) line up in the proper order by. hydrogen -bonding to their complementary bases on. DNA, the nucleotides are joined together by a DNA. dependent RNA polymerase enzyme , and a piece of. mRNA is produced. â¢ UNLIKE what happens in DNA replication where both. strands are copied, only ONE of the two DNA strands. is transcribed into mRNA (remember that RNA is a. single-stranded molecule).
