PPT-Types of mutations Mutations are changes in the genetic material

There are two basic types of mutations Gene mutations mutations that produce changes in a single gene Chromosomal mutations mutations that produce changes in whole chromosomes Gene mutations . Changes in . DNA. that affect genetic information. Gene Mutations. Point Mutations – changes . in one or a few. nucleotides. Substitution. THE FAT CAT ATE THE RAT. THE FAT HAT ATE THE RAT. Insertion. 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.

Mutation: Mistake in DNA replication or an environmental effect that . results. in a change to the nitrogenous bases in DNA or RNA. . 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. . Point mutations. single base change . silent mutation. no amino acid change. redundancy in code. missense. change amino acid. Changes the final protien. nonsense. change to stop codon. Stopping prematurely . 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 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 . 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 . INTRODUCTION. In 1865, Mendel showed that genes transmitted genetic information and in the first part of the 20. th. century, their patterns of transmission were studied extensively.. Although these classical genetic studies provided little insight into the molecular nature of genes, they did demonstrate that the genetic material must perform three essential functions: . mutation. Mutations. Actual Mutations . in fruit flies. What is a mutation?. A mutation is any change in a cell’s DNA. A mutation can occur in an individual gene. - results in a single changed protein.
