Briefly describe how the experiments of Avery, McCarthy, and MacLeod, building on the work of Griffith?
satela [25.4K]
The Avery–MacLeod–McCarty experiment<span> was an experimental demonstration, reported in 1944 by </span>Oswald Avery<span>, </span>Colin MacLeod<span>, and </span>Maclyn McCarty<span>, that </span>DNA<span> is the substance that causes </span>bacterial transformation<span>, in an era when it had been widely believed that it was </span>proteins<span> that served the function of carrying genetic information (with the very word </span>protein<span> itself coined to indicate a belief that its function was </span>primary<span>).

It was the culmination of research in the 1930s and early 20th Century at the </span>Rockefeller Institute for Medical Research<span> to purify and characterize the "transforming principle" responsible for the transformation phenomenon first described in </span>Griffith's experiment<span> of 1928: killed </span>Streptococcus pneumoniae<span> of the </span>virulent<span> strain type III-S, when injected along with living but non-virulent type II-R pneumococci, resulted in a deadly infection of type III-S pneumococci.

In their paper "</span>Studies on the Chemical Nature of the Substance Inducing Transformation of Pneumococcal Types: Induction of Transformation by a Desoxyribonucleic Acid Fraction Isolated from Pneumococcus Type III<span>", published in the February 1944 issue of the </span>Journal of Experimental Medicine<span>, Avery and his colleagues suggest that DNA, rather than protein as widely believed at the time, may be the hereditary material of bacteria, and could be analogous to </span>genes<span> and/or </span>viruses<span> in higher organisms.</span>

In comparison with the renal cortex, fluid in the proximal tubule is hyperosmotic.
ArbitrLikvidat [17]

The proximal tubule fluid is more hyperosmotic than the renal cortex, but this does not influence what is causing the acid-base disruption.

<h3>How does hyperosmotic work?</h3>

In the extracellular space, the first drop in temperature results in the formation of crystals, which creates a hyperosmotic environment that draws water out of the cells and causes them to contract. Organelles & biological membranes are damaged as a result of inner crystal formation as the temperature drops.

<h3>What transpires inside a hyperosmotic environment to a cell?</h3>

A cell submerged in a 10% dextrose hyperosmotic , osmotic pressure solution would initially lose area as water departs and then start gaining proportion as glucose is delivered through into cell as moisture follow by osmosis. This is because water crosses cell surfaces more quickly than solutes do.
