Error rates in DNA replication, proofreading and mismatch repair systems in E. coli are about 10-10 per base pair per round of replication.
Based on this, how many mutations per base pair would you expect to see in a population of 1010 E. coli cells (e.g. of a TSB culture of E. coli)

describe how the Methyl-directed mismatch repair system in E. coli which DNA strand is the correct strand and determines which DNA strand has the mutation. describe how DNA methylation is heritable during replication how epigenetic modifications are involved in genomic imprinting, X-inactivation, and regulation of tissue/cell specific gene expression (including the general roles of TrxG and PcG group proteins). ***Are these heritable during mitosis or meiosis? Are these reversible? Can you support your answer?

Fill in the Blank 1. DNA replication in E. coli begins at a 245 base pair sequence called • The initiation of DNA replication at this site begins with the binding of the protein, to multiple 9 base pair repeats regions. The association of these proteins generate superhelical tension which unwinds the 13 bp repeat region called the . The next step of initiation involves the loading of the protein (a helicase) onto the 13 bp repeat region by another...

10. The amount of DNA in one E. coli cell is found to be 5 fg (femtogram, 10-15 g). Given that the molecular weight of one base pair of DNA is 600 Dalton and 1 Dalton equals 1.66 x 10-24 g, how many base pairs of DNA are there in one E. coli cell? A. 1.8 x 106 B. 2 x 106 C. 5 x 106 D. 7.2 x 106 E. None of the above

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
