Answer:
A) A single base pair change.
Explanation:
Point mutation is a change in a single base pair of a nucleotide. This comes as a results of mistakes made during DNA replication, induced by ultravoilet radiations, extreme heat and X-rays. There are three types of point or substitution mutations; change, deletion and insertion. The nucleotide bases are either mistakenly inserted, changed or deleted, thus changing the resulting protein or amino acid being coded for.
After translation of the polypeptide
in the ribosome, the polypeptide enters the cisternae of the rough endoplasmic reticulum.
Here, the folding of the polypeptide begins with the aid of chaperons proteins.
At the end of the RER, vesicles with the completely folded protein bud off and enters
the Golgi apparatus where the proteins are transported to its destination.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
