I explain the stages of the cell cycle and the structure of DNA as well as evaluating the cell cycle and DNA sequence. I then discuss different things that can go wrong during each stage of replication and finally I evaluate the impact of variation in the DNA sequence using strengths and weaknesses

Similarities between eukaryotic and prokaryotic cells 1) Semi-conservative 2) Bidirectional Prokaryotic cells 1) Circular DNA 2) Single origin of replication Eukaryotic cells 1) Linear DNA 2) Multiple origins of replication New strands are always synthesized from: 5' --> 3' end of each strand Template strand is read: 3' --> 5' Chain extension occurs: by adding a dNTP to free 3' end of growing polynucleotide chain DNA polymerase DNA s...

Which of the following describes the way in which DNA is replicated? a) Dispersive Replication b) Conservative Replication c) Semi-Conservative Replication d) Leading duplication - Answer- c Which of the following is NOT true about replication points of origin? a) There can be 100s or 1000s of points of origin simultaneously in a eukaryote b) There are two replication forks formed at every point of origin c) The opening of a point of origin is so the DNA polymerase can fit between ...

DNA Replication Written Exam . DNA replication steps 1) Helicase- unwinds the parental double helix 2) DNA topoisomerase - upstream of helices alleviating torsional strain 3) Single-strand binding proteins (SSBP) stabilize unwound DNA, aided by DNA gyrase (topoisomerase). 4) Primase synthesizes a short RNA primer for DNA polymerase to bind to in the 5' to 3' direction to start replication on each strand. 5) DNA polymerase synthesizes the leading strand in 5' to 3' direction...
