In a bacterial species with multiple chromosomes,_____.
A)having one or two chromosomes has no evolutionary impact
B)it is very simple to distinguish between a chromosome and plasmid purely based on size
C)scientists postulate the use of a microfilament structure to ensure partition of both chromosomes to each daughter cell
D)duplicate genes that differ by mutations classify the organism as diploid

Question

Quizplus · Accepted Answer

In bacterial species with multiple chromosomes, partitioning of each chromosome to each daughter cell during cell division is crucial for successful reproduction. To ensure this, scientists have proposed the existence of a microfilament structure that helps in the segregation of both chromosomes. Having one or two chromosomes can have evolutionary impacts, and it is not always easy to distinguish between chromosomes and plasmids purely based on size. Duplicate genes that differ by mutations do not classify the organism as diploid in bacterial species.
