SpyIntel [72]

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 :

In order for a cell to become cancerous, oncogenes must be ___ and tumor suppressors ___.
ella [17]
<span>In order for a cell to become cancerous, oncogenes must be active and tumor suppressors inactive. Oncogenes are genes which carry genetic material capable of inducing cancer. Tumor suppressors, on the other hand, function as a sort of "anti oncogene." In other words, tumor suppressors work to stop uncontrolled cellular growth and prevent cells from becoming cancerous. So if oncogenes are active and tumor suppressors are inactive, then there is nothing to prevent the cell from growing cancerous.</span>
