I have no idea how to solve this

Question

Good evening everyone. I'm struggling with this task for my anatomy & physiology assignment, what i have to do is to transcribe the following DNA sequence into mRNA:  GGTCAATGCCATAAG , and then, use the following codon chart to translate it into an amino acid sequence. Please help me solve and understand this, all the help offered would be greatly appreciated.

             

Answer 1

DNA is made of the nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T). These are used to translate for mRNA, which is also made of nucleotides but with uracil (U) replacing thymine (T). When translation from DNA to mRNA happens, A is matched with U and G is matched with C. So in your sequence of GGTCAATGCCATAAG you just match the pairs together to make: CCAGUUACGGUAUUG. Now amino acids are made with 3 nucleotide sequences so you just break this mRNA strand up into triplets. CCA, GUU, ACG and so on. Then you can use those codes to refer to the chart and determine which amino acid they correlate with.
