An allele is like a trait or a specific gene.
Synthesis of a protein destined to function in the nucleus occurs AT THE RIBOSOMES.
Proteins are synthesized in the ribosomes. Newly synthesized proteins that are meant for the nucleus usually possess a localization sequences which direct it to a protein on the nuclear membrane through which it will enter into the nucleus.<span />
<span>Formation of bivalents lead to spindle fibers from opposite poles attaching to homologous chromosomes.

RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
Answer:
substitution - a base was changed
Explanation:
The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.
An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)
A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)
