Recently, scientists noted that stained chromosomes from rapidly dividing cells, such as human cancer cells, contain numerous dark, dotlike structures. Chromosomes from older human cells that have stopped dividing have very few, if any, dotlike structures. The best generalization regarding these dotlike structures is that they .

The options

1.) will always be present in cells that are dividing

2.) may increase the rate of mitosis in human cells

3.) definitely affect the rate of division in all cells

4.) can cure all genetic disorders

The CORRECT ANSWER IS 2.)

2.) may increase the rate of mitosis in human cells

Explanation:

There happen to be a scratch in the given question.

1.) can be disapproved since it is observed in the question that it as to do with to swiftly dividing cells, and not all forms of cells. Then it look up the idea of older cells showing how it possesses a little amount, which makes it looks as if it involves all cells. I think clarity is needed. If you can recall or infer that it does not as to do with cells as a whole, the option is good as being discarded.

2.) Seems to director thought in the right direction, as it seek to raise the rate of division, or could be formed as a form of the division and then tend to decrease in function as the cells become old.

3.) can be disregarded since, we can't say that the dots speed up the rate or that they are being formed in the division.

4.) It as some humour in it - the idea seems cool though and scientists should consider it probably, the dots and what it does

I would infer on 2.) to be the correct hypothesis a scientist will like to checkout.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
