regulatory genes

Question 3

errors of the genetic code

Answer 3

mutations

Question 4

occurs when broken pieces of a chromosome attach to the wrong chromosome

Answer 4

translocation

Question 5

occurs when a segment of a chromosome breaks off and is lost

Answer 5

deletion

Question 6

Answer 6

inversion

Question 7

when one or more nucleotide in the sequence is changed in the sequence

Answer 7

point mutations

Question 8

when a nucleotide is removed and replaced with a different nucleotide

Answer 8
