Describe how a cellular response is reached when using G-protein coupled receptor.

Biology
1 answer:
ra1l [238]3 years ago
4 0
When a signaling molecule binds to the GPCR, the G protein alpha subunit exchanges GDP for GTP. The alpha subunit dissociates from the beta and gamma subunits and interacts with other molecules, ultimately triggering a cellular response. ... GTP is hydrolyzed to GDP, and the signaling molecule comes off of the receptor.

What factors influence the amount of DNA you have?
Free_Kalibri [48]

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.

The quantity and quality of DNA can be greatly improved by performing PCR.

* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.

The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.

This table shows the codons found in messenger RNA. Using this information, what sequence of nucleotides in the template strand
Viktor [21]

The sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.

<h3>What are Nucleotides?</h3>

Nucleotides may be defined as a molecule that consists of a nitrogen-containing base, a phosphate group, and a pentose sugar.

The codons that codes for the given amino acids are as follows:

  • Phe = UUC
  • Ser = UCC
  • Gln = CAA.

mRNA is synthesized from a template DNA strand based on a complementarity mechanism.

Therefore, the sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.

How are these Tissues protected?​
Tom [10]

Answer:

The cells of the body's surface form the outer layer of skin. Inside the body, epithelial cells form the lining of the mouth and alimentary canal and protect these organs. Epithelial tissues help in absorption of water and nutrients

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
