PLEASE HELP PLEASE PLEASE PLEASE PLEASE HELP PLEASE PLEASE PLEASE PLEASE HELP PLEASE PLEASE PLEASE
igor_vitrenko [27]

Answer:

B

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

<u>So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not. </u>

Hope this helps! ;)

Explain why a glycine residue at position 12 of the G protein Ras is only active in the presence of growth factors but Ras with
sasho [114]

Explanation:

At position 12 of G protein Ras there is a normal amino acid attached to it called Glycine. Which make Ras protein a highly controlled protein. However, there is another amino acid called aspartate at 12 position which make Ras vulnerable by the formation of weak GTPase enzyme activity and GTP binding. Which prevent Ras from turning off. This the reason why aspartate in oncogenic. Furthermore, weak binding of GTP has influence because its binding can not be hydrolyzed.

Reference Research Paper

Morris, K. M., Henderson, R., Suresh Kumar, T. K., Heyes, C. D., & Adams, P. D. (2016). Intrinsic GTP hydrolysis is observed for a switch 1 variant of Cdc42 in the presence of a specific GTPase inhibitor. Small GTPases, 7(1), 1-11.

What is the difference between the position of the surface proteins and the membrane -spanning proteins
shepuryov [24]
<span>Surface proteins are specialized integral membrane proteins that allow communication between the cell and the extracellular space. Membrane spanning proteins are integral proteins that span the entire phospholipid bilayer.These trans membrane proteins contains one or more membrane spanning domains as well as domains from four to several hundred residues long,extending in to aqueous medium on each side of the bilayer.</span>
