What is the correct order below for the genetic information in DNA to make a polypeptide?
a- the mRNA moves into cytoplasm
b- the ribosome and mRNA causes the amino acid to join together in the correct order to form a polypeptide
c- mRNA is made as a copy of the genetic code for a polypeptide.
d-the mRna attaches to a ribosome
e-part of the DNA molecule unwinds and unzips

The first thing that would happen would be e: part of the DNA molecule unwinds and unzips. This would serve as a template for new DNA replication for the polypeptide. Once the DNA has separated, probably "c" would be next: mRNA is made as a copy of the genetic code for a polypeptide. Next, the mRNA would move into the cytoplasm ("a) in search of a ribosome, which are the manufacturers of proteins. The mRNA would then attach to the ribosome ("d") and serve as the template for the assembly of the amino acids to be joined together in the correct order for the production of the polypeptide.
It should be observed this is a natural phenomenon, the replication error rate is extremely low, although mistakes do occur. These mistakes in replication are called "mutations", and can have the following effect on the organism: 1) a beneficial effect, something that would be good, 2) a disastrous effect, something that could be life-ending for the organism, and 3) no effect at all, due to the fact that many codons produce the same effect. This last mutation is known as a "silent" mutation, in that it shows no change whatsoever, despite the fact a genetic change occured.
