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. Elie Traer. September 13, 2012. Outline. Genetic tests and methodology. Cytogenetics. , i.e. large chromosomal abnormalities. FISH, smaller chromosomal changes. Genetic mutations. AML. Evolution of genetic tests in diagnosis and prognosis. 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 . 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. http://io9.gizmodo.com/10-unusual-genetic-mutations-in-humans-470843733. Unharmful. Mutations. Mila . Kunis. has complete . heterochromia. . Kate Bosworth has . sectoral. . heterochromia. . Angelina Jolie has central . SAT VOCABULARY TWO So now we are going to study how DNA can mutate and cause genes to change. People who are deaf cannot hear and their deafness can be genetic. If someone is deaf, no sounds are ________. 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). 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. 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 . Unit 8: Protein Synthesis . 6A: Identify components of DNA, identify how information for specifying the traits of an organism is carried in the DNA, and examine scientific explanations for the origin of DNA.. KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. Science. Learning intention. To understand the different types of mutations. . You will need. A pen and a piece of paper or a laptop to record your answers. .
