Question

You isolate a gene that you think could be important for blood vessel formation. After you isolate it and put in bacteria, you sequence it (above) to better understand its function. Identify the first 10 amino acids (write you answer using the single letter codes, without spaces between them)

Answer 1

The sequence has not been given. It has been attached.

Answer:

QPGREDRPLP

Explanation:

A codon consists of a set of three mRNA nucleotides which corresponds to an amino acid. There are 64 codons which code for 20 amino acids (AA). A DNA sequence is first transcribed to mRNA which is then translated to form protein. According to the given sequence, the first 10 amino acids for this particular sequence will be:

GTC = CAG mRNA = Glutamine AA (Q)

GGT = CCA mRNA = Proline AA (P)

CCA = GGU mRNA = Glycine AA (G)

GCA = CGU mRNA = Arginine AA (R)

CTT = GAA mRNA = Glutamic acid AA (E)

CTG = GAC mRNA = Aspartic acid AA (D)

TCT = AGA mRNA = Arginine AA (R)

GGC = CCG mRNA = Proline AA (P)

GAT = CUA mRNA = Leucine AA (L)

GGC = CCG mRNA = Proline AA (P)

Hence, in single letter codes these amino acids will be represented as :
