Put the following steps in the correct order from 1-9
storchak [24]

Answer:

transcription of mRNA from DNA

small ribosomal subunit binds to mRNA

initiation complex formed with addition of large ribosomal subunit

translocation

codon recognition (non-initiating site)  

peptide bond formation

ribosome reads a stop codon

polypeptide chain is released from the P site

ribosomal subunits dissociate

Explanation:

The above describes the process of translation in the ribosome. After transcription of DNA to mRNA, the mRNA is taken to the ribosome to undergo translation, here the mRNA binds to the small ribosomal subuits and to other initiation factors; binding at the mRNA binding site on the small ribosomal subunit then the Large ribosomal subunits joins in.

Translation begins (codon recognition; initiating site) at the initiation codon AUG on the mRNA with the tRNA bringing its amino acid (methionine in eukaryotes and formyl methionine in prokaryotes) forming complementary base pair between its anticodon and mRNA's AUG start codon. Then translocation occurs with the ribosome moving one codon over on the mRNA thus moving the start codon tRNA from the A site to the P site, then codon recognition occurs (non-initiating site again) which includes incoming tRNA with an anticodon that is complementary to the codon exposed in the A site binds to the mRNA.

Then peptide bond formation occurs between the amino acid carried by the tRNA in the p site and the A site. When the ribosome reads a stop codon, the process stops and the polypeptide chain produced is released and the ribosomal subunits dissociates.

What surface features does Comet Hale-Bopp have? Unless there is no surface features.
antiseptic1488 [7]

Answer:

  • The bright head of the comet Hale-Bopp, called the comma, is shown near the Sun. The combo is made up of dust and gas, concealing a solid comet nucleus made of rock, dust, and ice.
  • The solid nucleus or core of the hale bopp comet consists mainly of ice and dust coated with black matter, and ice formed mainly of frozen water but possibly other cold substances, such as ammonia, carbon dioxide, carbon monoxide and methane.

Hope it helps!

What role do receptor sites play in drug activity? What role do receptor sites play in drug activity? The receptor site removes
KATRIN_1 [288]

Answer: The receptor site is the location that a drug binds to, altering the function of a biomolecule.

Explanation:

The drug receptors site, are the sites where the sites where the drug molecules bind.  Basically, a low number of receptors exists and the extent to which the molecules occupy their sites differ with the concentration of drug.  The receptor site changes the conformation and function of the binding molecule of the drug.
