Gene identification of predicted proteins in the genome is designed to discover the metabolic features of an organism

b.

In a particular organism or group of organisms, one particular domain can be expanded to perform a particular function

c.

Comparison of the domain content of an entire proteome with that of another proteome cannot help in revealing the biological roles of diverse domains in different organisms

d.

Different proteins are mosaics of domains that occur in different combinations in a given protein

Discuss
Answer: (b).In a particular organism or group of organisms, one particular domain can be expanded to perform a particular function
Q132.
Which of the given statements is incorrect about Ancient Conserved Regions?

a.

The method involves database similarity searches of the SwissProt database with human, worm, yeast, or E. coli genes and identification of matches with sequences from a different phylum than the query sequence

b.

An analysis of ACRs that predate the radiation of the major animal phyla some 580–540 million years ago suggested that 50–60% of coding sequences are ACRs

c.

These ACRs may represent proteins present at the time of the prokaryotic–eukaryotic divergence

d.

Phylogenetically diverse groups of organisms have been analyzed for the presence of conserved proteins and protein domains that have been conserved over long periods of evolutionary time, called ancient conserved regions or ACRs

Discuss
Answer: (b).An analysis of ACRs that predate the radiation of the major animal phyla some 580–540 million years ago suggested that 50–60% of coding sequences are ACRs
Q133.
Which of the given statements is incorrect about Horizontal Gene Transfer?

a.

The genomes of most organisms are derived by vertical transmission, the inheritance of chromosomes from parents to offspring from one generation to the next

b.

It is the acquisition of genetic material from a different organism

c.

The transferred material becomes a temporary addition to the recipient genome

d.

An extreme example is the proposed endosymbiont origin of mitochondria in eukaryotic cells and chloroplasts in plants

Discuss
Answer: (c).The transferred material becomes a temporary addition to the recipient genome
Q134.
Which of the given statements is incorrect about Horizontal Gene Transfer?

a.

It is a significant source of genome variation in bacteria, allowing them to exploit new environments

b.

Such transfer is rendered possible by a variety of natural mechanisms in bacteria for transferring DNA from one species to another

c.

Detection of HT is made possible by the fact that each genome of each bacterial species has a unique base composition
