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)
C. Cut out the insulin gene from human DNA.
this is done with an enzyme called lygase
I think it would be that it produces hormones that regulate cell metabolism
During meiosis i, the Kinetochores for each pair of sister chromatids of each homologue, attach to microtubules from the same pole.
<h3>What is Kinetochores ?</h3>
Large protein structures called kinetochores link chromosomes to the microtubules of the mitotic and meiotic spindles to transfer the replicated DNA from a mother cell to its daughters.
- Its primary role is to stabilise the spindle's microtubules so that, during metaphase, the chromosomes may align correctly at the metaphase plate before being pulled toward the opposing poles of the cell during anaphase. In order to ensure appropriate chromosome segregation, the kinetochore is crucial.
- Each chromosome binds to microtubules from just one spindle pole, and each pair of homologues does so from the other pole. In order to be separated during metaphase I, homologous pairs rather than individual chromosomes line up at the metaphase plate. stages of meiosis type I.

The answer would be a)40
After completing the punnet square you find that 1/4 of the bunnies will have white fur since white fur is recessive and would only be characterized if no dominant genes are present
1/4 of 160= 40
