Hershey and Chase used the 35S isotope to label proteins. How does this isotope differ from the 32S isotope found in greatest na

tural abundance, and why did they choose 35S instead of 32S?
A. 35S has more protons than 32S; Hershey and Chase used it because it has a greater mass.

B. 35S has fewer protons than 32S; Hershey and Chase used it because it is radioactive and can be easily traced.

C.35S has more neutrons than 32S; Hershey and Chase used it because it is radioactive and can be easily traced.

D. 35S has fewer neutrons than 32S; Hershey and Chase

Answer:

The correct answer would be C. ³⁵S has more neutrons than ³²S; Hershey and Chase used it because it is radioactive and can be easily traced.

Sulfur-35 (³⁵S) is one of the isotopes of the sulfur which has 16 protons (same as sulfur-32) but 19 neutrons as compared to the 16 neutrons of sulfur-32.

It is a radioactive isotope which breaks down by beta-decay and gets converted into ³⁵Cl.

They used ³⁵S for radioactive labeling of the protein coat of the bacteriophage. It helped them to trace the movement or transfer of protein efficiently.

"35S has more neutrons than 32S; Hershey and Chase used it because it is radioactive and can be easily traced" is the way <span>this isotope differ from the 32S isotope found in greatest natural abundance and this is why they chose 35S instead of 32S. The correct option among all the options given in the question is option "C".</span>

Binocular vision, the ability to focus both eyes on the same object at the same time, usually does not develop until ?
vekshin1

Binocular vision, the ability to focus both eyes on the same object at the same time, usually does not develop until  4-5 months of age.

Binocular vision is the type of vision in which both the eyes look in the same direction to form a 3-D image of the object. One single image is formed by both the eyes. When any disorder appears regarding the binocular vision, the core reason is the misalignment of both the eyes.

Eyes are the organs of vision. They are present in a pair embedded in a socket like region on the skeleton below the forehead. The image is formed at the retina of the eye. The image formed is an upside down image.

How do earth's spheres interact to cause weather/climate?
miss Akunina [59]
The atmosphere transfers heat energy and moisture across the Earth. Incoming solar radiation (insolation) is redistributed from areas in which there is a surplus of heat (the equator) to areas where there is a heat deficit (the North and South Pole). This is achieved through a series of atmospheric cells: the Hadley cell, the Ferrel cell and the Polar cell (Figure 2). These operate in a similar way to, and indeed interact with, the ocean conveyor.

For example, as the oceans at low latitudes are heated, water evaporates and is transported poleward as water vapour. This warm air eventually cools and subsides. Changes in temperature and CO2 concentrations can lead to: changes in the size of atmospheric cells (in particular, the Hadley cell is susceptible to these alterations); warming in the troposphere; and disproportionately strong warming in Arctic regions. The strong interactions between ocean and atmospheric dynamics, and the significant feedback mechanisms between them, mean that climate researchers must consider these Earth components as interlinked systems. The necessity to assess ocean-atmospheric changes at the global scale has implications for the way in which research is conducted. It is only by integrating palaeo evidence of past changes, with present day monitoring, and projected models,

Hershey and Chase used radioactive isotopes to label different parts of the phage. They grew one batch of phage in the presence
AlekseyPX

The sulphur would lable the capsule and the phosphorous the nucleic acid.

<h3><u>Explanation</u>:</h3>

Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.

This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
