Which of the following organisms would have the highest predicted gene density (most genes per megabase of dna) in genomic dna?

which of the following organisms would have the highest predicted gene density (most genes per megabase of dna) in genomic dna?

chicken
e. coli bacteria
mouse
human

The correct answer will be option- E.coli bacteria

Explanation:

Gene density refers to the ratio of the number of genes/ million base pairs.

The gene density helps us understand the complexity of the organism as the simple organism like prokaryotes possesses high gene density as compared to eukaryotic organisms.

In the given question comparing the E.coli with other eukaryotes shows that genes present per base pairs lies in 500-1000 genes/Mb while mammals posses 12-15 genes/Mb.

This happens as the bacterial gene lacks the non-coding sequences called introns which are found in the eukaryotic genome.

Thus, E.coli bacteria is the correct answer.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom
