Dna Replication Activity Guide Answer Key Google Classroom Key terms DNA structure DNA is a nucleic acid one of the four major groups of biological macromolecules Nucleotides All nucleic acids are made up of nucleotides In DNA each nucleotide is made up of three parts a 5 carbon sugar called deoxyribose a phosphate group and a nitrogenous base
For this activity students use beads and wire to create a DNA molecule that shows the sugar phosphate backbone as well as the paired nitrogen bases After they are done with the keychains we use them to see what happens during DNA replication Visit http accessexcellence AE AEC AEF 1995 ross jewelry html to Key points DNA replication is semiconservative Each strand in the double helix acts as a template for synthesis of a new complementary strand New DNA is made by enzymes called DNA polymerases which require a template and a primer starter and synthesize DNA in the 5 to 3 direction

DNA Replication Activity Guide Exploring DNA 1 List at least three reasons why a cell must undergo division 2 Imagine you are cutting a bagel one of the most common household injuries and you get a cut The cut heals How do the new cells compare to the original pre cut cells
Templates are pre-designed documents or files that can be utilized for numerous functions. They can conserve time and effort by supplying a ready-made format and layout for developing various kinds of material. Templates can be utilized for individual or expert tasks, such as resumes, invites, leaflets, newsletters, reports, discussions, and more.

The 3 steps of replication 1 Enzymes unzip the helix 2 DNA polymerase binds nucleotides together to form new strands that are complementary to the original strands 3 Two identical DNA molecules result Human chromosomes have origin s of replication where the DNA is unzipped so replication can begin
DNA replication follows base paring rules A T C G Sometimes during DNA replication a base is inserted deleted or substituted with a different one changing the DNA sequence of a gene Changes in the DNA sequence of a gene can lead to changes in the protein it codes for Give each student or pair of students one copy of the instructions Major Enzymes The process of DNA replication is catalyzed by a type of enzyme called DNA polymerase poly meaning many mer meaning pieces and ase meaning enzyme so an enzyme that attaches many pieces of DNA During replication the two DNA strands separate at multiple points along the length of the chromosome These locations are called origins of replication because replication begins
11 Which of the three mechanisms of DNA replication explains how two molecules of DNA are synthesized from one 12 Create a schematic model showing DNA replication Include and label the parental strands of DNA the leading strand and the lagging strand in your diagram Be sure to label the 3 and 5 ends of the DNA
