Bacteria cells have no nuclei. They do have something similar to a nucleus with is called a nucleoid which kind of like a simpler version of a nucleus. It still contains DNA but has less complicated parts to it than a nucleus does. Nucleoids are also spread out through the cell versus a nucleus which is more contained in the cell. Bacteria is prokaryotic which means that they do not have a nucleus or other specialized organelles. They have a cell membrane which basically keeps everything in, kind of like our skin. They can definitely reproduce, thats why we get sick and have to take antibiotics that help to stop their reproduction. And they have 'means of locomotion' which basically means that they can move around. They move through their pili and flagella.

Why is it essential that the regulatory mechanisms that activate glycogen synthesis also deactivate glycogen phosphorylase? (sel
Alex_Xolod [135]
This is because such a mechanism of regulation prevents the simultaneous addition and removal of glucose monomers, preventing unnecessary reactions. Additionally. the two processes occur in the same location in the sell, thus this regulation makes the net process more efficient. When glycogen phosphorylase is phosphorylated its activity increases and vicevarsa.

How do genetic modification variations likely to differ from genetic sexual reproduction variations
ololo11 [35]

Answer:

The  genetic modification variations result in the change in the genome of the organism. In this case, the variations result in expression of a trait in different form than usual. These variations results in genetic mutation, which can be inherited from one generation to another.

In sexual reproduction, the genome of the organism is not altered. In this only an exchange between the maternal and the maternal alleles takes place, these changes does not result in mutations.

You’re welcome :)

Studies peg the number of proteins in the human body to be around 10,000 to several billions. This diversity is a result of the
Harrizon [31]

Answer:

The correct answer is - option B.

Explanation:

The diversity of numbers of proteins in the human body is due to the differences in the structure of proteins. This change or difference in the structure of proteins is mainly affected by the sequence of amino acids.

The order of sequence of amino acid segment or residue in the peptide chain of the protein affects the structure of the particular protein which also leads to change in the secondary and tertiary structure of the protein.

Thus, the correct answer is - option B.
