DNA Replication Flashcards
<p><em>Define</em></p>
<p><strong>DNA Replication</strong></p>
<p>The process of a parent molecule of double-stranded DNA making two identical copies</p>
<p><em></em></p>
<p><strong>When does DNA replicate?</strong></p>
<p>Before a cell divides</p>
<p><em>Define</em></p>
<p><strong>Semi-conservation Replication</strong></p>
<p>When DNA is copied, each new molecule is made of one old strand and one new strand</p>
<p><em>Describe the </em></p>
<p><strong>Process of DNA replication</strong></p>
<p>Two strands of a DNA molecule are separated; <br></br>Enzymes add complementary base pairs to each strand; <br></br>The newly formed strands and original strands twist into a helix to make two separate molecules</p>
<p><em>What is</em></p>
<p><strong>Helicase</strong></p>
<p>Enzyme that separates the two strands of DNA during replication</p>
<p><em>What is</em></p>
<p><strong>DNA Polymerase</strong></p>
<p>Enzyme that adds complementary nucleotides to single strands of DNA</p>
<p><em>What is the</em></p>
<p><strong>Replication fork</strong></p>
<p>Region of DNA that has been separated</p>
<p><em>What is the</em></p>
<p><strong>Replication bubble</strong></p>
<p>Area of DNA that has been separated to be copied; area between two replication forks, which move in opposite directions</p>
<p><em></em></p>
<p><strong>One strand of DNA reads<br></br> T A C G C G A<br></br>What is the complementary DNA sequence?</strong></p>
<p>A T G C G C T</p>
<p><em>Define</em></p>
<p><strong>Sister Chromatids</strong></p>
<p>Identical chromosomes that are the result of DNA replication</p>
<p><em>Define</em></p>
<p><strong>Centromere</strong></p>
<p>Section of two sister chromatids that are connected</p>
<p><em>Identify parts A and B</em></p>
<p><strong></strong></p>
<p>A: Centromere<br></br>B: Chromatid (one half of a pair of <i>sister chromatids</i>)</p>
