Question

1) When comparing the genome of a prototypic bacterium such as E.coli, and the genome of a human, which of the following statements is true?

a. The genome of E.coli is a single, circular, double stranded piece of DNA; the human genome is comprised of several linear chromosomes  

b. The genome size of E.coli is approximately 4.5 x 10⁶ base pairs; the size of the human genome is approximately 3.2 x 10⁹ base pairs

c. The genome size of E.coli is approximately 4.5 x 10⁶ base pairs; the size of the human genome is approximately 3.2 x 10⁷ base pairs

d. Statement A and B are both true

e. Statement A and C are both true

2) The following statement about Single Nucleotide Polymorphisms (SNPs) is false

a. A specific combination of SNPs that occur together on the same chromosome is called a haplotype

b. a SNP is present in the population with a minor allele frequency of greater than 1%

c. a SNP is nucleotide variation observed in genes but not observed in extragenic regions of the chromosome.

d. SNPs are used in genome-wide association studies to link specific genetic variation to human disease

e. SNPs occur approximately every 300 nucleotides in the human genome

Answer 1

Ans 1- option d is correct that is statement A and B both are true for prokaryotes and human genome

Ans 2 - option e is correct - SNP occur approximately every 300 nucleotide in human genome is false about SNP
