How do mutated tumor suppressor genes affect the cell cycle?

Biology
1 answer:
Marrrta [24]3 years ago
8 0
Tumor suppressor genes encode for proteins that inhibit or slow the progression of the cell cycle through a specific stage.they also encode for check point control proteins that arrests the cell cycle if the DNA is damaged or the chromosomes are abnormal. Mutation in the tumor suppressor genes that cause a loss or decreased function would lead to uncontrolled cell cycle leading to abnormal proliferation and the cell may become cancerous.

The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th
Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is  2.22 10^ 12 molecules / µm3

Relative time of divergence from a common ancestor can be estimated by:.
igomit [66]

The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

<h3>What is sequence homo-logy?</h3>

In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.

A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.

Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.

In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
