Which of the given statement is incorrect about the Chromosomal Rearrangements?

ক
Comparison of the number of rearrangements in a given period of evolutionary history may vary significantly from one organism to the next

খ
If gene A has a neighboring gene B, then if an ortholog of A occurs in another genome, there is an increased probability of an ortholog of B also occurring in the other organism

গ
If gene A has a neighboring gene B, then if an ortholog of A occurs in another genome, the B ortholog is more likely to be a neighbor of the A ortholog of the genome of the second species if the two species are more divergent

ঘ
In general, the order of orthologs is not well conserved in prokaryotes when the genomes have diverged sufficiently that the orthologs have < 50% identity
Which of the given statement is incorrect about the observations made with regard to gene order?

ক
Order is highly conserved in closely related species

খ
Order in closely related species becomes changed by rearrangements over evolutionary time

গ
As more and more rearrangements occur, there will no longer be any correspondence in the order of orthologous genes on the chromosome of one organism with that of a second organism

ঘ
Order is less conserved in closely related species
Two species that have recently diverged from a common ancestor might be expected to have a ________ set of genes and ________ chromosomes with these genes positioned along the chromosomes in the same order.

ক
distinct, similar

খ
similar, distinct

গ
similar, dissimilar

ঘ
similar, similar
Other functional classification schemes for genes include a broader category for genes involved in the same biological process, e.g., a three-group scheme for energy-related, information-related, and communication-related genes has also been used.

ক
True

খ
False
An approach to classification of genes that encode enzymes is to examine relationships among multiple enzymes that perform the same biochemical function in the same organism.

ক
True

খ
False
The designation ECa.b.c.d conveys information. Which of the following is not one of it?

ক
One of twelve main classes of biochemical reactions

খ
The group of substrate molecule

গ
The nature of chemical bond that is involved in the reaction

ঘ
Designation for acceptor molecules (cofactors)
Which of the given statement is incorrect regarding MAGPIE?

ক
It analyzes the genome using a set of automated processes

খ
It is designed for high-throughput genome sequence analysis

গ
It is unable to locate potential promoters

ঘ
It automatically annotates genomic sequence data and maintains a daily up-to-date record in response to user queries about one or more genomes
GeneQuiz focuses on deriving a predicted protein function, based on a variety of available evidence, including the evaluation of the similarity to the closest homolog in a database.

ক
True

খ
False
