The Meselson and Stahl experiment starts with E. coli containing 15N/15N labeled DNA grown in 14N media. Which result did Mesels
cricket20 [7]

Answer:

No 15N/15N labeled DNA was observed in second generation

Explanation:

Meselson and Stahl were doing an experiment to find out the semi-conservative mode of replication of DNA. The first cultured bacteria in 15N medium which was containing a heavy isotope of nitrogen. The DNA synthesized here had more density. After that they transferred the bacteria to the 14N containing medium. When bacteria reproduced and new strands of DNA were synthesized, they observed the following -

  • The first generation had hybrid DNA with 15N/14N strands
  • The second generation had both hybrid 15N/14N DNA and 14N/14N DNA strands
  • There was no 15N/15N DNA observed.

In this way they proved that one strand of DNA is kept conserved during the replication.

The type of hormone, such as a steroid, which passes directly through the cell membrane to nuclear receptors to cause changes in
Ede4ka [16]

The type of hormone, such as the steroid, which passes directly through the cell membrane to nuclear receptors to cause changes in gene expression within the cell, is known as hydrophobic.

Hydrophobic steroid hormones are transported in the circulation, largely bound to plasma carrier proteins. Steroids are overall hydrophobic because of they have common tetracyclic hydrocarbon core.

Hence, the steroid hormones are lipid-soluble in hydrophobic environments and they able to pass through the cell membrane of cell. Steroid hormones have the ability bind with receptors and change their structure and causing that complex to easily pass into the nucleus in order to alter or change gene expression.
