The answer would be "<span>Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate </span>transcription of RNA and process mRNA during mitosis.
I’m not exactly sure, but I’m thinking it may be A . I just learned about this unit previously .
The amount of p-nitrophenol relates to the cellobiase activity - The change in amount leads to a change in the yellow color of the reaction that presents only in presence of p-nitrophenol.
Cellobiase is an enzyme that catalyzes the hydrolysis of β1-4 glycosidic bonds found in cellulose. Organisms like fungus and some bacteria are able to break down cellulose with help of this enzyme. The substrate is cellulose and the product is glucose catalyzed by cellobiase. It is clear/colorless, and therefore difficult to detect quantitatively.
Enzymatic Activity of Cellobiase
- p-nitrophenyl glucopyranoside is used as a substrate which is an artificial substrate that binds to the Cellobiase and is broken down similarly to cellulose and produces glucose and p-nitrophenol.
- This p-nitrophenol reacts with a basic solution called stop solution that stops the reaction and turns the solution yellow.
- The amount of yellow color is proportional to the amount of p-nitrophenol present which means this color help in knowing the Cellobiase activity.
Thus, the change in amount leads to a change in the yellow color of the reaction that presents only in presence of p-nitrophenol.

<span>It's simple. There's creal definition of gene isolation technique. So the answer is: The type of genetic engineering that often involves isolating genes from one species and introducing them into another is called gene isolation technology.</span>
Answer:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female.
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease.
Explanation:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female. This disorder is never transmitted to male child by the father or in other way we can say that there is no male to male transmission. For example Fragile X syndrome
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease. Males are more affected by this disorder as compared to females. For example - hemophilia
. This disorder is never transmitted to male child by the father just like the X linked dominant disorder or in other way we can say that there is no male to male transmission.
