Answer:
The correct answer would be (c)[m phase].
M phase or mitotic phase is the phase of the cell cycle in which the actual division of chromosomes (karyokinesis) into two daughter nuclei takes place.
It can be divided into four stages namely prophase, metaphase, anaphase, and telophase.
During anaphase, the sister chromatids of each replicated chromosomes are separated from each other and are pulled in opposite side with the help of mitotic spindle.
Then during telophase (last stage of M phase), the separated chromosomes reach either pole of a dividing cell. In addition, nuclear membranes are reformed around each chromosome set which forms the two daughter nuclei.
M phase is followed by cytokinesis which divides the cytoplasm, cell organelles, cell membrane, and two daughter nuclei into two daughter cells.
Note: Chromosome duplication or replication takes place in S phase while the division of the replicated chromosomes takes place in M phase.
Rosalind Franklin was the one who pioneered the structure of DNA through his X-ray diffraction images at King's College. His failure to explain the double helix structure was the reason why Watson and Crick were the person who were accounted by the discovery. The huge model by Cirick and Watson proved the theory of Franklin who failed to give an evidence.
A monomer can be defined as the molecule that is capable of binding in long chains. The monomers bind together to form different polymers by the process of polymerization.
The monomer of carbohydrate is monosacchride. The monomer of proteins is amino acid, and that of lipids is glycerol and fatty acids. These three macromolecules are wrongly paired in the question.
The monomer of nucleic acids is nucleotide. This is correctly matched.
Hence, the correct answer is 'Option B - nucleic acids - nucleotides'.
Answer:
In the first reaction, energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product. In the reactions of the second stage, the hydrogen is combined with carbon dioxide to make glucose.
