permanent change in the DNA sequence of a gene Mutations in a genes DNA sequence can alter the amino acid sequence of the protein encoded by the gene GOOD BAD NEUTRAL. or. How a perfectly good system can go wrong go wrong go wrong. There are 2 types of mutations. 1)Chromosomal rearrangements. . There are too many or too few chromosomes. (nondisjunction and polyploidy). Updated Summer 2015. by J. D. Hendrix. Mutations: Definitions. Lethal . mutation: results in death of the cell, and therefore cannot be propagated or studied. Conditional mutation: One that is expressed only under certain environmental conditions; for example, a temperature-sensitive mutation. Jessica Hawley. Compiled . By: . C. Kohn, Waterford, WI.

What happens if there is a mistake (. mutation. ). in the DNA code?. Possibly proteins won’t be made or are made improperly.. If the mutations occur in the gametes, the offspring’s DNA will be affected positively, negatively, or neutrally.. Dun . dun. dun!!!!! . Nobody’s perfect all the time . About 1/10 billion base pairs end up with a error or mutation . Mutation: . Mistake in replication or environmental effect that results in a c. Changes in the genetic material. Mutations can occur in two different types of Cells:. 1. Somatic (body) cells. 2. Gamete (sex or germ) cells. Mutations in somatic cells. Usually result in killing that body cell only.. Given a mutation, identify its type. Predict how a mutation will affect a protein.. Mutations. Changes in genetic material (DNA). 2 main types of mutations. Point mutation- change in one or a few nucleotides (letters). The types of proteins an organism possesses depend upon the . sequence of nucleotides. The two main types of gene mutations include:. Point mutation: one base pair is replaced for another base pair.. Main idea: Gene expression is regulated by the cell, and mutations can affect this expression. Gene Regulation . Cells have the ability to control which genes are transcribed and when they are transcribed. What if it’s NOT just the number?. Gene Mutations.
