Question

Which of the given statement is incorrect about Clusters of functionally related genes?

(a) In microbial genomes, genes specifying a metabolic pathway may be contiguous on the genome where they are coregulated transcriptionally in an operon by a common promoter

(b) In related organisms, gene order on the chromosome is least likely to be conserved

(c) As the relationship between the organisms decreases, local groups of genes remain clustered together, but chromosomal rearrangements move the clusters to other locations

(d) The function of a particular gene can sometimes be predicted, given the known function of a neighboring, closely linked gene

This question was addressed to me in unit test.

My question is based upon Sequence Assembly and Gene Identification in portion Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

The correct choice is (b) In related organisms, gene order on the chromosome is least likely to be conserved

Easiest explanation: In related organisms, both gene content of the genome and gene order on the chromosome are likely to be conserved.
