To answer:
The reason of two cells produced by the cell cycle is genetically identical.
Introduction:
Cell cycle is the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cell and mitosis is the part of the cell-division cycle.

Explanation of Solution
Actively dividing eukaryote cells pass through a series of stages collectively called as the cell cycle: two gap phase or growth phase (G1 and G2); and S phase (for synthesis), in which the genetic material is duplicated; and an M phase in which mitosis partitions the genetic material and the cell divides. The period between mitotic divisions that is G1, S and G2 is phase is known as interphase.
From a single cell, the cell cycle produces two cells that contain the same genetic information. The resulting daughter cells are genetically identical with each other and with their parent cell because DNA synthesis in the S phase of the cell cycle creates an extra copy of each DNA molecules, giving rise to two genetically identical sister chromatids.

- Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forward

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
