Do First: Answer in your DFAD 5 mins Answer the questions below and show your work in your DFAD. SHOW YOUR WORK!! Answer questions 1-3 from your guided notes. Be sure to write your answer in your DFAD. Also be sure to show your work. Today we will be using the privacy folders for the Do First. So set one up for your self and answer the 3 questions silently and independently. Once you are done, you may take down your privacy folder and place your DFAD in the proper folder. I have included a step by step guide for Dihybrid crosses as well as the say you should be setting up the question.

Examples of Human mutations Baldness Colorblindness Webbed fingers

Types of mutations Substitution mutations THE FAT CAT ATE THE RAT THE FAT HAT ATE THE RAT

Substitution mutation DEFINITION: single base substitution One nitrogenous base must be replaced by another base pair. Is any other part of the DNA strand effected?

2. Frameshift mutations THE FAT CAT ATE THE RAT THE FAT HCA TAT ETH ERA T

Frameshift mutation Insertion: One nitrogenous base pair is inserted in the DNA, shifting each base pair to the right. Deletion: One nitrogenous base pair is deleted in the DNA, shifting each base pair to the left.

Is any other part of the DNA strand effected Is any other part of the DNA strand effected? Take 30 secs to turn and talk to a partner about how this mutation effects the rest pf the DNA strand

Chromosomal mutations THE FAT CAT ATE THE RAT THE FAT RAT

Chromosomal Mutations A change to the genetic make up of a specific chromosome.

Mutation A change of the DNA in an organism

Mutation effect the production of Amino Acids 1. Blood and other cells contain DNA from the body.   2. Mutations add genetic variations within a species population.

Causes of Mutations 3. Mutations can be accidental Mistakes when replicating DNA Carcinogen: cancer-causing mutagen Radiation: gamma rays, x-rays, ultraviolet rays Chemicals: acids, bases, some metals

Causes of Mutations Mutations can be passed down from parents is it affects gametes (eggs and sperm) Mutations in the gamete cells are inherited. Ex – Color blindness Mutations in body cells are not inherited and only effect the individual. Ex – Lung Cancer

Independent Practice 7 mins Answer the questions on to classify each mutation. Once you get to the Codon chart STOP Work must be done silently and independently. No Talking. If you have a question or request raise a silent hand and be patient. For independent practice, today we will be working silently and independently for 7 minutes. 7 mins

Independent Practice 7 mins Answer the questions on the Codon Chart. Work must be done silently and independently. No Talking. If you have a question or request raise a silent hand and be patient.

Questioning: Ask a question about a specific step. Ask a question related to a specific section of the guided notes. Discussion Directly answer each question on your paper by solving each problem step by step. Directly respond to the questions and comments of peers. Used discussion stems to promote productive discussion. Had appropriate section of guided notes open while working on the corresponding section of independent practice. Maturity & Behavior Maintain a respectful tone 100% of the time. Re-evaluate your work when someone had a different answer. Participate and remain on task 100% of the time. Show Your Work Always be able to show evidence for what you state as fact, this is a good time to use your Biology Notebook. Group Practice For group work today, we will be using a Discussion Rubric. We will be working at a level two volume. During this time you need to be comparing your answers to make sure you and your table have all the correct answers. 8 mins
