Genes that code for proteins that promote the cell cycle and inhibit apoptosis are called _____.
garik1379 [7]

Genes that code for proteins that promote the phone cycle and inhibit apoptosis are known as proto-oncogenes.

In distinction to the cell proliferation-stimulating function of proto-oncogenes and oncogenes that power the cell cycle forward, tumor suppressor genes code for proteins that generally function to preclude mobile growth and division or even promote programmed mobile death (apoptosis).

<h3>Which of the following is a gene that generally codes for a protein that suppresses mobilephone division?</h3>

Tumor suppressor gene.

Why are some cells in interphase longer than others?
jeyben [28]
Cells spend most of their lives, about 78 percent of the time, not dividing in a phase called interphase. During interphase the cells get larger, replicate their chromosomes for cell division, synthesize substances that are essential to cell division, and build materials for growth and development.

In many animals, height is an example of a polygenic trait. Which types of natural selection can affect polygenic traits? I. dir
Marat540 [252]

The question is incomplete as it does not have the options which are:

I. only

I. and II. only

II. and III. only

I, II, and III.

Answer:

I, II, and III.

Explanation:

The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.

The natural selection can be explained by the phenotype produced in a population and that depends on the genes.  The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.

Thus,  I, II, and III are correct.
