The answer is tubulin cyclin and a
cyclin-dependent kinase
The two components that
constitute an active maturation-promoting factor (MPF) is tubulin cyclin and a
cyclin-dependent kinase. MPF stimulates the mitotic and meiotic phases of the
cell cycle. It has the ability to phosphorylate target proteins at a specific point
in the cell cycle and thereby control their ability to function.
Answer: Synaptic gap
A synaptic gap is the space between two neurons where the axon of a sending neuron communicates with the dendrites of a receiving neuron by using chemical messages.
Explanation:
Neurons are joined end to end in a special way, the axon of one neuron forms a junction with the dendrites of the next neuron. However, the two neurons do not touch, but leave a gap called synaptic gap.
Thus, synaptic gap is the answer.
Answer:
tagging the sharks
Explanation:
To learn their behavioral patterns researchers are tagging the sharks. Doing so allows the researchers to track their movements individually and gather data as to how they move, where they migrate to, how many migrate together, etc. All this information is extremely valuable and when pieced together can shed light on why they have certain behavioral patterns or traits.
<span>Yeast cells are the active ingredient to convert organic material into alcohol. Ethanol fermentation (production of alcohol) takes place when oxygen is not present in yeast cells and they still need to produce energy. The yeast cells well take monosaccarides such as glucose or fructose and break them down to form energy the by products are carbon dioxide and alcohol.</span>
As demonstrated by long-range mapping of restriction endonuclease recognition sequences and genomic cloning, we found that the human genes encoding interleukin 3 (IL 3) and granulocyte/macrophage colony-stimulating factor (GM-CSF) are tandemly arrayed on the long arm of chromosome 5, separated by 9 kilobases (kb) of DNA. This close physical linkage of genes with similar structure and biologic function suggests that these cytokines may have evolved from a common ancestral gene. This linkage in evolution of two relatively divergent genes further implies that some of the other lymphokine and cytokine genes that appear to share as much or more sequence similarity than do IL 3 and GM-CSF may be distantly related members of a cytokine gene family.
