Why must each chromosome make a copy of itself before the m phase begins

1 answer:

3 0

The each chromosome makes the copy of itself before the M Phase in mitosis because the resultant daughter cell the chromosomes is genetically identical.

Explanation:

The parent cell in the chromosomes make the copy before mitosis. The copy is occurred during the S phase of inter phase. During the mitotic M phase, the cell divides the copied DNA and cytoplasm to make two new cells.

M phase involves two distinct related processes which is mitosis and cytokineses ;the cell growth steps into the new stage and cellular energy is developed on the division in the phase .

In humans, what is the only homologous chromosome pair that isn't the same?

Katen [24]

Answer;

-23 in males

In humans, 23 in males is the only homologous chromosome pair that isn't the same.

Explanation;

-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.

The ________ plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking

Anna11 [10]

The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.

The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

Why is ATP known as the energy currency? 5 line answer plz

guapka [62]

Answer:

ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
