DNA REPLICATION MODELING KEY: T = A = C = G = S = P = Name Class Date 2. Modeling. Unit 5 DNA Structure and Replication Lab (30pts) Create a model for DNA. This lab activity corresponds to CIBT’s DNA Molecule Model. Be sure to create a key (explain what represents each part of DNA) 5pts Phosphate: blue Deoxyribose … With the instructor’s help, paste your model to another lab group model. Follow your teacher’s model and fold page in half on this line. DNA replication begins at specific sites called origins of replication.A eukaryotic chromosome may have hundreds or even a few thousand replication origins. DNA unzips. Construct a DNA Model. Shannan Muskopf March 18, 2017. So, DNA replication occurs within a fork-like structure in which the lagging strand loops around in a proposed “trombone model” to orient the replication enzymes for repeated synthesis and joining. 5. Students color each nucleotide and paste them in an anti-parallel orientation. Proteins that start DNA replication attach to the DNA and separate the two strands, creating a replication bubble.At each end of the replication bubble is a Y-shaped region where the parental strands of DNA are being unwound. You could use different types of food, different animals, or cut out different colors/shapes of paper, it is entirely up to you to decide how you will create your model of DNA. Distribute Blackline Master # 2 – Modeling DNA and DNA Replication (one per student). 3. List any errors with the replication if they occurred: Replication #1 A T A T T A T A C G C G C G AND A G G C G C T A T A G C G C Replication #2 A T A T Include a key that indicates which nucleotide each color represents in your sketch. The model of DNA below is ready to be copied. Some people are not able to create a profile due to medical reasons. DNA Structure dry lab is a cut n' paste activity in which students build models of DNA and then answer 10 general questions about the structure of DNA. Now put your lab group initials on your model. Four Nucleotide Model Pieces Exercise 1: DNA Replication. Working in their groups, students will follow the directions on Blackline Master # 2 to create a model of DNA and DNA replication. DNA replication- the process of making an exact copy of each of the two strands of DNA. It is considered that this mechanism helps to maintain the integrity of DNA during the replication cycles. Modeling DNA Replication and Protein Synthesis continued 5. The download is a PDF file. Fold a flap to the back of the page along this line. DNA Molecule Activity Genetics High School Molecular Biology. 1). If you need one of these activities for your child, I suggest taking a look at one of the many DNA Model Activity Worksheet Answers. 1. t ORIGINAL DNA STRAND ORIGINAL DNA STRAND 3. PART B: MODELING DNA REPLICATION 6. Downloads. When you have completed your model of one DNA segment, make a sketch of the model in the space below. DNA Molecule HS Student Edition (CIBT) DNA Molecule MS Student Edition (CIBT) DNA Molecule Post-Lab Questions (CIBT) Watson & Crick Reading (CIBT) Watson&Crick Reading Qs Student Edition (CIBT) Each stand acts as a template for the construction of a new complementary strand of DNA (Fig. model by matching up the stars, and you can attach the top of the phosphates to the sugars by matching up the squares. This simple activity asks students to cut out shapes of nucleotides, each having a phosphate, a base, and a deoxyribose sugar. Compared to the original double helix, evaluate the copies made during three attempts of DNA replication. 21. Use colored pencils or pens to designate the pushpin colors. Fill in the shapes for the original The teacher can follow Blackline Master #1 for the Model Guide. All DNA pieces are included, complete with teacher tips and an answer key. These people may be able to acquire a DNA Model Activity Worksheet Answers to assist them in their research.
