What holds amino acid chains within a protein in shape?​

Answers

Answer:

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they serve as the catalysts for virtually every biochemical reaction that occurs in living things. This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.

After cell division each daughter cell hasa.a lower surface area/volume ratio than the parent cell
b.a higher surface area/volume ratio than the parent cell
c. more DNA in its nucleus than the parent cell
d.less DNA in its nucleus than the parent cell

Answers

The surface area to volume ratio will be higher as compared to the parent cell after cell division. Hence, option B is correct.

Further Explanation:

Cellular division is known to be the process through which the parental cell segregates into two or more daughter cells. This process generally occurs as a segment of a larger cell cycle. It comprises of 2 main stages, interphase and M-phase. Interphase is further segregated into:

  1. G1 phase wherein the cell prepares itself for the upcoming events.
  2. S phase is the phase where DNA synthesis occurs
  3. G2 phase is the phase wherein the cell gets ready for the M phase.  

M phase or mitotic phase is the next stage after interphase and is segregated into 4 phases:

  1. Prophase is the first event which occurs and in this the nuclear envelope disappears, mitotic spindle formation starts, and chromosome condensation begins.  
  2. Metaphase is wherein the alignment of chromosome occurs on the equatorial plate.  
  3. Anaphase is the phase wherein the chromosomes segregate towards the opposite ends
  4. Telophase is the final stage and division of the two daughter cells is completed.  

During cellular division, the cell segregates into 2 daughtercells and as the cell becomes larger, the volume elevates rapidly as compared to its surface area. Hence, option B is correct. The reduction in the cell’s ration of the volume to surface area makes it difficult for the cell to transport the required substances in and move out the waste products quickly enough for the cell to survive.

Final answer:

OPTION A.

After cell division, each daughter cell has a higher surface area/volume ratio than the parent cell. This is due to the division resulting in two smaller cells with same DNA content. This increased ratio is beneficial for the exchange of material across cell membrane.

Explanation:

After cell division, each daughter cell has a higher surface area/volume ratio than the parent cell. When a cell divides, it splits into two smaller cells, reducing the volume but not reducing the surface area in the same proportion. This results in each daughter cell having a larger surface area relative to its volume. This increased ratio is important because it allows for more efficient exchange of nutrients and waste products across the cell membrane.

The amount of DNA in each daughter cell is the same as in the parent cell because during cell division, the DNA is copied and then distributed evenly between the two resulting cells. Therefore, option c and d are incorrect.
