Chapter 23.2, Problem 4R
Summary Introduction
To review:
The differences between the two hypotheses for the wide range of genome sizes among organisms.
Introduction:
The size of genome in different organisms from bacteria to humans is very different. The genome of the bacteria Mycoplasma has about 470 genes, while the genome of humans has almost 21,000 genes. There is some sort of correlation between the organismal complexity and the genome size, but this is not a direct correlation.

What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes?
Select the four correct statements.
a. DNA content and ploidy in various cell types( sperm and somatic cells) are related
b. DNA is found to be the only macromolecule in eukaryotes that has different subunits.
c. Gene transfer is a direct evidence as it has been facilitated by recombinant DNA techniques.
d. The correlation of the action and absorption spectra of ultraviolet light support the interpretation that DNA is a genetic material.
e. DNA is shown to be present in ribosomes, matrix, and nucleus, where genetic function is performed.
f. DNA is shown to be present in mitochondria, chloroplasts, and nucleus, where genetic function is performed.
Explain how the different “-omics” involved with the three major parts of the central dogma can be used to study this new species. What are molecular techniques/tools (sequencers) that can be used to study each of these? How would you sequence the genome efficiently (i.e., lowest amount of time and money)?

- Price et al. (1999. J. Bacteriol. 181: 2358–2362) conducted a genetic study of the toxin transport protein (PA) of Bacillus anthracis, the bacterium that causes anthrax in humans. Within the 2294-nucleotide gene in 26 strains they identified five point mutations—two missense and three synonyms—among different isolates. Necropsy samples from an anthrax outbreak in 1979 revealed a novel missense mutation and five unique nucleotide changes among ten victims. The authors concluded that these data indicate little or no horizontal transfer between different B. anthracis strains. (a) Which types of nucleotide changes (missense or synonyms) cause amino acid changes? (b) What is meant by horizontal transfer? (c) On what basis did the authors conclude that evidence of horizontal transfer is absent from their data?arrow_forwardAssume 2x108 reads of 75 bps long are obtained from a next-generation sequencing experiment to sequence a human genome.

- A commercially available strain of P. syringae marketed as FrostbanB is used to combat frost damage. This is a naturally occurringstrain that carries a loss-of-function mutation in a gene that encodesa protein that is expressed on the surface of the bacterium andnucleates frost formation. In addition, researchers have used recombinantDNA techniques to eliminate the function of this gene. Discuss the advantages and disadvantages of using the nonrecombinantstrain compared with a recombinant version.arrow_forwardYou were tasked to conduct a population genetic survey of a diploid insect population.
