What was known before Franklin and Wilkins conducted their studies of DNA? Check all that apply. DNA is found in the nucleus of

kvasek [131]

Answer:

The correct answer will be-

1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

are the correct options.

rodikova [14]

A mechanism that is effective in maintaining a normal glomerular blood pressure only if the systemic mean arterial pressure remains between 80 and 180 mm hg is called renal autoregulation.

<h3>What is renal autoregulation?</h3>

Autoregulation is the inner characteristic of blood vessels present in end organs, like heart, kidney, and mind, by which they dilate or constrict in response to pressure changes, thus help to keep the blood flow generally steady.
Usually our body tries to regulate our blood pressure in range of 50 to 150 mm Hg.
Regulation of renal blood flow and glomerular blood pressure in kidneys is called renal autoregulation.
There are 3 mechanisms of renal blood flow namely myogenic response (MR), tubuloglomerular feedback (TGF) and third mechanism that is independent of TGF but slower than MR.

How do cells know that there is something wrong with the DNA?

sveta [45]

The short answer is that cells respond to the chemical environment in which they find themselves. The cells around them, the specific conditions, and feedback from the environment all create specific chemical cues that inform the cells to which genes should be expressed, and in what amounts. Chemicals include hormones, cytokines, general signaling molecules, such as cAMP, etc.

i literally hopped on google for this, lol.
i hope this helps though. :)
