The correct answer to the question is option E

THE STATEMENT IS TRUE FOR MITOSIS AND MEOSIS II

In mitosis and meosis II,chromatids are seperated from each other.

Explanation: During the metaphase,chromosomes are attached to spindle fibres and they move to the centre of the cell while the CHROMATIDS(duplicated chromosomes known as sister chromatids) are pulled apart to the opposite poles of the cell.seperate into two daughter nuclei and the cells divide into two daughter cells each with a full copy of DNA.

In Meiosis II, The two cells produced in meiosis I go through the events of meiosis II in synchrony. During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.

Mitosis is a cell division of the nucleus for the main purpose of repair, growth and production of new somatic cells.the cells produces by mitosis are considered as diploid cells because they have a paired set of chromosomes.

While meosis is cell division of the nucleus creating 4 haploid gamete cells from a diploid cell.

Answer from: Quest

a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of amino acids , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in genes . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called transcription ), and the mrna is transported to the ribosome . protein synthesis, also called translation , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the nucleotides of mrna three by three, in units called codons , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the amino acid chain goes on to be processed and folded to make the final, functional protein
