Protein synthesis is a complicated process involving DNA being transcribed to RNA, which is then translated into amino
acids. Complete the DNA-to-amino acid table for three consecutive codons with the appropriate nucleotides and amino
acids using a codon table. Nucleotide and amino acid options can be used multiple times or not at all.

The use of a DNA template to make a messenger RNA product molecule is a process referred to as:
reverse transcription (using the RNA-dependent-DNA-polymerase enzyme)
transcription (using the DNA-dependent-RNA-polymerase enzyme)
self-replication (using the DNA-dependent-DNA-polymerase enzyme)
translation (using the large and small ribosomal subunits)
reverse translation (using the small and large ribosomal subunits)
"Unlike what happens in DNA replication, where both strands
are copied, only one of the two strands is transcribed into
MRNA. The DNA strand that contains the gene is sometimes
called the sense strand, or coding strand, and the DNA strand
that gets transcribed to give RNA is called the antisense strand,
or noncoding strand. Because the sense strand and the antisense
strand are complementary, and because the DNA antisense
strand and the newly formed RNA strand are also
complementary, the RNA molecule produced during
transcription is a copy of the DNA sense strand... The only
difference is that the RNA molecule has a U everywhere the
DNA sense strand has a T."
Consider the following segment of a DNA sense strand:
(5') CAA-ACT-ACG-GCG-TTG-CAG (3’)

DNA contains the "genetic code" for the protein. DNA is double-stranded, but only one strand is transcribed into MRNA. The MRNA then goes into the cytoplasm where it is translated into protein with the help of TRNA. At each stage of the process, there is base complementarity (A pairs with T/U and C pairs with G) between the nucleic acids involved to ensure the integrity of the DNA blueprint for the protein being produced. Therefore, some of the four strands of nucleic acids involved will match (except U replaces T in RNA) and some will have base complementarity. Indicate whether there is matching (1) or base complementarity (2) between the following nucleic acids.
