MMG 301 Module 14 Homework questions
Comparing the different generations of DNA sequencing, which would be most appropriate for a 10 Mbp piece of DNA that could not be fragmented? a) fourth generation b) third generation c) second generation d) first generation
a) fourth generation
The genome sequence of an organism can provide information about the organism's _____________. a) genes, function, and evolutionary history b) genes, size, and function c) function, evolutionary history, and morphology d) function, size, and evolutionary history
a) genes, function, and evolutionary history
Which of the following is NOT included in the genome? a) genes that encode RNAs b) proteins c) noncoding regions of DNA d) coding regions of DNA
b) proteins
The field of study that can reveal how genes function, reveal how organisms interact with the environment, and show evolutionary relationships is __________. a) transcriptomics b) proteomics c) genomics d) comparative genomics
d) comparative genomics
If a researcher wanted to compare the enzymatic capacity to degrade compounds in a water column at various depths under a specific set of conditions, which would be the most useful approach? a) metaproteomics b) metabolomics c) genomics d) metagenomics
a) metaproteomics
"Horizontal gene transfer" refers to the transfer of genes from one organism to another, as occurs during conjugation between bacteria. How does this differ from vertical gene transfer? a) In vertical gene transfer, genes are transferred by a vector such as a bacteriophage. b) Conjugation can involved horizontal or vertical gene transfer, depending on the physical orientation of the bacteria involved. c) In horizontal gene transfer, genes are transferred from one mature adult organism to another. In vertical gene transfer, genes are transferred from adults to offspring. d) In horizontal gene transfer, genes are transferred between two organisms of the same species. In vertical gene transfer, genes are transferred between two organisms of different species.
c) In horizontal gene transfer, genes are transferred between two organisms of the same species. In vertical gene transfer, genes are transferred between two organisms of different species.
Sequencing an organism's genome often leads to identification of hypothetical proteins, which are characterized as ____________. a) proteins that are overexpressed b) proteins that likely exist with known functions c) proteins that likely exist through their function is unknown d) proteins that are expressed
c) proteins that likely exist through their function is unknown
Gene duplication is thought to have had a significant influence on the evolution of microbes because _________________. a) the duplicated gene can allow for increased transcription and synthesis of the gene product b) the duplicated gene can serve as a "back-up" copy c) the duplicated gene can be mutated, possibly leading to a useful new gene function of product, while the original copy can still perform its original (and possibly essential) genetic function d) the duplicated gene can be given away to another organism by conjugation
c) the duplicated gene can be mutated, possibly leading to a useful new gene function or product, while the original copy can still perform its original (and possibly essential) genetic function
Researchers discover a new species of bacterium that has an unusual metabolism. However, it has biochemical and morphological similarities to other species. What is the most comprehensive and effective approach to determine how to classify these bacteria? a) The bacteria should be classified with other bacteria that have the most similar morphology. b) The bacteria should be classified with the other bacteria that use the most similar biochemical pathways. c) Because of their unusual metabolic pathways, the bacteria should be classified in a new group. d) The bacteria should be classified by using genomic analyses to construct phylogenies.
d) The bacteria should be classified by using genomic analyses to construct phylogenies.
