Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...

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...

Simple Sequence DNAs are known to be located in which areas of the chromosome - found in centromere and some in telomere; interacts with the kinetochore Simple Sequence DNA - constitutes about 6% of the human genome, also called satellite DNA, concentrated near the centromere, backward slippage is used, number of repeats are vastly different, simple sequence is mobile; doesn't code for anything Gene - a unit of heredity that is transferred from a parent to offspring and is held to determin...
