Researchers test a group of cells for DNA content immediately following mitosis and find the average to be 12 picograms of DNA p

er nucleus. Based on this information, how many pictograms of DNA would they expect to find at the end of the S phase and at the end of the G2 phase

Answer:

The correct answer is - 24, 24

Explanation:

In any type of cell division, there is an interphase stage before the actual process of division which is a preparatory process or stage that includes different substages like G1, S, and G2. S phase is a synthesis of the cell cycle responsible for duplication or replication of the DNA.

So, at the end of the S phase, the DNA amount becomes double its initial amount and remains the same in the G2 phase. So, if the initial amount is 12 picogram then it will be double in the S phase and remain 12 in G2 as well.

Explain what a mosaic is and then explain why the term fluid mosaic model is used to describe the plasma membrane
zalisa [80]
Fluid mosaic is a term used to describe the current model of the cell membrane. Cell membranes are basically double layers (bilayers) of molecules called phospholipids.A mosaic is a structure made up of many different parts.<span> Mainly because of the way the plasma membrane is made up. It is fluid because it can wave and wobble like fluid, a bit sticky though. Due to the phospholipids sticking together. It is called mosaic because there are various proteins stuck inside the fluid creating a kind of patchwork or mosaic </span>

DNA ___________ is important because it ensures that when a cell divides, the two resulting cells have the same genetic code. Pl
slega [8]

Answer: Replication

Explanation: When the cell is preparing to divide it will <u>replicate</u> its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)

What is food energy in the form of glucose?
tiny-mole [99]
<span>Glucose is the human body's key source of energy as it provides energy to all the cells in our body. Glucose also is critical in the production of proteins, lipid metabolism and is a precursor for vitamin C production.</span><span><span>Glucose is the sole source of fuel to create energy for all brain and red blood cells.</span> The availability of glucose influences many psychological processes. When glucose levels are low, psychological processes requiring mental effort l(self-control, critical thinking and decision-making) become impaired.
