Identify how the deletion of a single nitrogen base in DNA can cause a harmful mutation in an organism.
ra1l [238]

Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence.  For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.
