Answer:

The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.

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.

If mitotic cell division is the only way a particular species of single-celled organism can reproduce, it is most likely that
leva [86]
If mitotic cell division is the only way a particular species of single-celled organism can reproduce, it is most likely that the rate of evolution in this species is slower than in one that reproduces sexually. This is asexual reproduction, which causes mutations in a population to accumulate and combine more slowly than sexual reproduction in a cell line, as the mutations would have to arise multiple times in one line, rather than a few separate times and then be allowed to combine sexually for the descendants to have those traits.
