Determine whether the following events occur during initiation, elongation, or termination. This is regarding protein synthesis.
erik [133]

Answer:

The provided events can be classified as:

Initiation

  • In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
  • In E. coli, mRNA binds to the 30S ribosomal subunit.

Elongation

  • In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
  • Initiator tRNA enters the P site.
  • In E. coli, EF-Tu hydrolyzes.
  • Translocation occurs

Termination

  • The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site

Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).

It is divided into three stages:

Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.

Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next  codon.

Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.

The osmolarity of physiological saline solution is 0.30 osmol/L.Assuming that the cell membrane is not permeable to its ions, is
Andrew [12]

Answer:

This question have two parts.

Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?

Answer:

Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.

Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?

Answer:

Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.

if you are interested to know more according to scientist read this research paper.

What are homologous structures in other species evidence of
Savatey [412]

Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor.

Write the function of pulmonary artery​
leonid [27]

Answer:

The pulmonary artery carries deoxygenated blood (blood whose oxygen content is relatively low) from the right ventricle to the lungs. The blood here passes through capillaries to alveoli and becomes oxygenated (as part of the process of respiration).
