Effects . of . Mutations. Learning Objectives. Identify different changes to DNA within both genes and chromosomes. Evaluate effects of changes to DNA on proteins produced and organisms’ overall survival. What Are Mutations?. Mutation: . Changes . in the nucleotide sequence of . DNA. Mutagen: . A physical or chemical agent that changes DNA. Mutation May . occur . in:. somatic cells (body cells): . will not be . Bases:. A, T, C, G. Codons:. Genes:. Chromosome:. DNA. Words. Chapters. Book.

There are 2 types of mutations. 1)Chromosomal rearrangements. . There are too many or too few chromosomes. (nondisjunction and polyploidy). 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 :. By Karl . Menzel. Is rearrangements or Point Mutations Faster. Synteny. Blocks and Chromosomes. Mouse Human. Chimp Human. Data Reading and Sliding Window. Human vs Chimp. Human vs Mouse. Mutation. Permanent change in the genetic material of an organism. All mutations in gametes are inheritable because they are copied during DNA replication. Somatic cell mutations occur in body cells. 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:. 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.. 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.. The sequence of bases in DNA are like the letters of a coded message or even the letters of a simple alphabet. . If we change the sequence of the letters do we change the nature of the message?. That . 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.. Science. Learning intention.
