5 Steps to DNA ReplicationEnzyme initiates (starts) replication and untwists the helix
Step 2: DNA unzips
Step 3: Free Nucleotides attach (the nucleotides bind to the unzipped DNA strands)
Enzymes check for errorsA T G C A G C G Step 4: Enzymes check for errors A G T
Step 5: Enzymes twist the new strands (creating the double helix) Results: 2 identical copies
5 steps of DNA ReplicationEnzyme initiates replication and untwists the helix DNA unzips Free nucleotides attach Enzymes check for errors Enzymes twist DNA – creating 2 double helix DNA stands
Semi-Conservative ReplicationOriginal DNA Original DNA New DNA
DNA Replication. Each cell within a body contains the same DNA sequence. Why? Before the cell divides, an exact copy of DNA is made- process called REPLICATION.
DNA Review What does DNA store that is important? If a DNA strand read AGT-CCG-GTA what would the complimentary strand read? What holds the nitrogen bases.
Replication copies the genetic information.
The DNA molecule unzips in both directions.
Goal: Students will be able to explain how DNA was identified as the genetic material, describe the basic processes of replication, transcription, and.
DNA Replication. Why is DNA Replication needed? When cells are dividing… During Interphase of Mitosis & Meiosis DNA must be copied so that each new cell.
DNA replication: DNA making DNA Why must DNA replicate? › So that when a cell divides, each new cell gets a copy of the DNA When does DNA replication.
KEY CONCEPT DNA replication copies the genetic information of a cell.
12-2 Chromosomes and DNA Replication Pg A. DNA and Chromosomes 1. Prokaryotes have no nucleus; contain a single, circular strand of DNA.
DNA Structure, Function and Replication
Name one scientist who was involved in the discovery of the structure of the DNA molecule.
DNA Replication What is it? How does it happen? Why does it happen?
DNA Replication. Chromosome E. coli bacterium Bases on the chromosome DNA is very long!... but it is highly folded packed tightly to fit into the cell!
Chapter 11 DNA and Genes Section 1 DNA: the Molecule of Heredity.
Notes: Pages 6 & 7. 1. 5-Carbon Sugar called DEOXYRIBOSE 2. Phosphate Group 3. Nitrogen Base (A, T, C, or G)
DNA Deoxyribonucleic Acid D – Deoxyribo N – Nucleic A – Acid.
D.N.A. DeoxyriboNucleic Acid
DNA Deoxyribose Nucleic Acid. DNA (deoxyribonucleic acid) Genetic Information in the form of DNA is passed from parent to offspring. Genes are the code.
DNA Deoxyribonucleic Acid. What are the building blocks of DNA? DNA is an organic macromolecule. It contains the genetic blueprint in life Shape is described.
