PPT-Notes on Mutations A change in DNA

Mutations Mutation a change in DNA not all mutations are harmful can happen in body cells and in gametes mutations are passed down to offspring only when they are in the . Types . of Mutations | . 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. DNA Polymerase can replicate DNA at a rate of . 50,000 base pairs per minute. !. That’s pretty fast – do you think it ever makes mistakes?. Mutations. Mutations. Changes in the genetic code. They come from mistakes that cells have made in copying their own DNA. . Day Monday Notes: Tuesday Notes: Wednesday Notes: Thursday Notes: Friday Notes: Saturday Notes: Sunday Notes: Workout Intervals Steady row Repeat four times for one set then take a break of 3 minu 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. 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.. (Chapter 12 Section 4). Mutation. - . A . Change in Genetic . Information . Causes . can be: . 1. ) . Genetic (DNA proofreader does not catch mistakes) . in Replication . or Protein Synthesis. . 2. 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. (Chapter 12). Presented by Dr. Laurie M. Erickson. Chair of the Department of Health Sciences. Blitstein Institute of Hebrew Theological College. Chicago, IL, USA.. 12.1-12.2 Mutations . Mutation:. any heritable change in the genetic material. Can the letters of any word be rearranged to form another word in English? Give examples. . If you rearranged the letters at random, is it likely that you would form another English word? Explain your answer. . 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. . You may need the internet to search for answers. . A substitution is a mutation that exchanges one base for another (switch . A . with a G) . changes . a codon to one that encodes a different amino acid and cause a small change in the protein produced. . Mutation may result in coding sequences for new amino acids in proteins or not!. Mutations can occur due to errors during DNA replication (. replication-dependent. mutations). Mutations can also occur independently of DNA replication (.
