Chaperone proteins or chaperones assist in the proper folding of proteins. Explain the process.
oksian1 [2.3K]

Proteostasis is mediated by chaperone proteins and protease systems, together with cellular clearance mechanisms such as autophagy and lysosomal degradation.

Chaperone proteins control assembly and inaccurate folding by binding to and stabilizing partly or completely unfolded protein polypeptides till the polypeptide chain is completely synthesized. Chaperone proteins also confirm the stability of unfolded polypeptide chains as they are being translocated into the subcellular organelles.

You determine that you have only three copies left of an important DNA fragment, so you decide to amplify it. Using flanking pri
kicyunya [14]

Hello. This question is incomplete. The full question is:

"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment? "

Answer:

Approximately 29 cycles of PCR would be required.

Explanation:

As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.

PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.

In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:

32 ^ x = 10 ^ 9

x = 28.3 = approximately 29 cycles.

What is the purpose of MITOSIS?
Mumz [18]

Answer:

D

Explanation:

A: to create sex cells of reproduction.

This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.

B. to provide the cells with food

This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.

C. To give the cell energy

This would be cellular respiration. It turns food and glucose into usable energy called ATP.

D.

This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
