Answer:

The answer is S-phase

Explanation:

Phases of the cell cycle. The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs

I can’t see your answer choices, but igneous rocks are made from cooled lava or magma. This is why these rocks are so brittle and grainy. I’ve attached a helpful image to better explain! Good luck!!!

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.
