As a ribosome translocates along an mRNA molecule by one codon, which of the following occurs? a. The polypeptide enters the E site. b. The tRNA that was in the A site departs from the ribosome via a tunnel. c. The tRNA that was in the P site moves into the A site. d. The tRNA that was in the A site moves to the E site and is released. e. The tRNA that was in the A site moves into the P site.

Answer 1
Answer:

Answer:

e. The tRNA that was in the A site moves into the P site.

Explanation:

Translation comprises 3 steps :

1) Translation initiation

2) Translation elongation

3) Translation termination

Translocation step is a part of translation elongation step which is followed by the peptidyl transferase activity of ribosome. Due to the peptidyl transferase activity of ribosome, the N terminal of newly entered amino acid (amino acid attached with tRNA i.e. aminoacyl tRNA or charged tRNA) at 'A site' attacks the C terminus of amino acid which is already present in the 'P site' of complex and amide bond is formed between amino acids leading to elongation of peptide chain. Then after, the uncharged tRNA which is present in the 'P site' is expelled out the complex via 'E site' while the tRNA that was in 'A site' moves into the 'P site'.

What happens to a cell during INTERPHASE?

Answers

What happens to a cell during interphase is when Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.

In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.a. True
b. False

Answers

It is true that in the DNAisolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

What is DNA isolation?

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellularcomponents using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensicscience, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.
