Replicate the following strand of DNA:
Original DNA-- A T G A A C C A T T C A G T A T G G

Original DNA:               ATG AAC CAT TCA GTA TGG

Complimentary DNA:   TAC TTG GCA AGT CAT ACC

mRNA molecule:          AUG AAC CGU UCA GUA UGG

AMINO ACID:               Methionine (Start) - Aspargine (Asn) - Arginine (Arg) - Serine (Ser)- Valine (Val) - Tryprophan (STOP)

2nd template:

Original DNA:               ATG  GGT   CTA  GCG  AAA  GAT

Complimentary DNA:   TAC  CCA  GAT  CGC  TTT   CTA

mRNA molecule:          AUG  GGU CUA  GCG  AAA  GAU

AMINO ACID:               Methionine (Start) - Glycine (Gly) - Leucine (Leu) - Alanine (Ala) - Lysine (Lys) - Apspartic Acid (Asp)

Explanation:

When you are forming the DNA complimentary strand you need to remember that they come in base pairs, and each base pairs up with a specific base. In the case of DNA the base pairs are the following:

A - T ; T - A

C - G; G - C

So:

For every A, its complimentary is T. For every T, it's complimentary is A.

For every C, it's complimentary is G. For every G, it's complimentary is C.

So in the case of your 1st DNA template:

Original DNA:                ATG AAC CAT TCA GTA TGG

Complimentary DNA:   TAC TTG GCA AGT CAT ACC

During transcription however, mRNA is formed. RNA does not have thymine (T), but Uracil (U) instead. So the base pairs would be different in the case of Adenine(A), thymine and Uracil.

A - U; T - A

C - G; G -C

So:

For every A, it's complimentary is U. For every T, it's complimentary is A.

For every C, it's complimentary is G. For every G, it's complimentary is C.

Going back to your 1st DNA template:

Original DNA:               ATG AAC CAT TCA GTA TGG

Complimentary DNA:   TAC TTG GCA AGT CAT ACC

mRNA molecule:          AUG AAC CGU UCA GUA UGG

Duing translation, tRNA brings the amino acids to the mRNA strand. There is a specific RNA codon sequence that codes for a specific AMINO ACID. These codons are 3 bases grouped together. You can use the table attached to see the amino acid each combination.

Amino acids are the building blocks of protein. The DNA templates determines the type of protein that will be made. The tRNA brings the amino acid to the mRNA template. Then it drops the amino acid off, which will bond with the next amino acid coded to attach to it.

So if you take the first mRNA codon AUG, you can see in the table that it codes for Methionine, which is a start codon, meaning this is the start of a new protein. It will then attach to the next amino acid that codes for the next codon which is AAC that codes for Aspargin. They will continue until it reaches a STOP codon, which means it would be the end of that protein.
