Mutations are changes in the genetic material. . Mutations may be genetic mutations or chromosomal mutations.. Genetic Mutations occur in the “code” on DNA or mRNA. Mistakes in . copying the DNA :. and Causes. What kinds of mutations can occur?. Mutations:. Mutations: are changes in the genetic material.. Mutations can produce changes in a single nucleotide to a whole chromosome. . Gene Mutations:. Polypeptides made up of amino acids. Proteins are polypeptides, numerous amino acids. First Recall Proteins------. **Peptide Bond between amino acids. **Notice the “R” group.

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.. M. istakes made in the DNA sequencing. They can have a range of effects.. They can affect the genetic information that is passed to offspring.. Cells have evolved various methods to deal with them. . 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). Understand how they occur. Analyze the different types of mutations. Understand how mutations affect amino acid sequences and proteins. Objective. Central Dogma. DNA is transcribed into RNA, RNA is translated into proteins. Small-scale mutations. Missense mutations. Nonsense mutations. Silent mutations. Frameshift mutations. Large scale mutations. Causes. Mutagens. The results of mutation. Mutations. Genetic mutations are changes in the DNA sequence, caused by various mechanisms.. Conditional mutations. Point mutations. In . point mutations . the sequence of the DNA has been altered at a single position. Where this change consists of replacing one nucleotide by another, it is known as a . Science.
