00:01
So, the first statement that we have been given is genomic islands typically represent the flexible gene pool of the bacterial population.
00:30
So, this statement is correct.
00:35
Why? because these genomic islands, they are basically like regions within the prokaryotic genome and these regions have been acquired through horizontal gene transfer.
00:57
So, these genes, they are often genes which provide selective advantage to the bacteria.
01:04
For example, genes which are involved in antibiotic resistance or in metabolism.
01:13
So, they contribute to the flexible like gene pool of the bacterial population.
01:20
The second statement that we have been given is the core gene pool of a species is represented by essential genes related to dna replication and gene expression.
01:56
So, this statement is also correct.
02:01
Because the core gene pool of like a prokaryotic species, it consists of genes which are found in all members and these genes are essential for all basic cellular functions like dna replication, gene expression and even cellular metabolism.
02:29
After this, the next statement that has been given to us is that genes in the flexible gene pool are not necessarily shared by all members of the species...
