It's a chemistry question why is it in biology?
Answer:
CAT - GGC - TAC mutates to CAT - GGC - TAG is the right answer
Explanation:
because substitution mutation is the change in the single base which result in change in codon which encode different amino acid and protein sequence changes.
for example in this
CAT - GGC - TAC encodes HGY protein
now after change in single nucleotide from C to G
CAT - GGC - TAG which encodes HG stop codon
Receptors on the plasma membrane either recognize a particle as acceptable or foreign.
The mRNA made from the section of DNA coding for the protein (the gene) exits the nucleus through a nuclear pore after getting modified. It can get modified by getting a poly-A tail and a methylated cap, along with removing the interfering sequences (introns).
