Answer:
Oxidation of pyruvate to produce Acetyl CoA
Cells grow during both Gap 1 and 2, but since we've to choose a proper answer, I'd go for A, the G1
Answer:
The correct answer will be option-A.
Explanation:
During anaphase, the spindle microtubules help the segregation of the chromosomes from the center of the cell at the metaphase plate.
These microtubules get attached to the chromosomes at kinetochore which helps in pulling of the chromosomes to opposite poles. The microtubules pull apart the sister chromatids when cohesin proteins degenerate.
The chromosomes do not show jiggling movement at the metaphase plate and thus, option-A is the correct answer.
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

A
