Hi
Below are five major steps of DNA or gene cloning:
1: You chose the gene or specific piece of DNA you need to clone and cut the gene with restriction enzymes from the source organism.
2: You need to choose a vector for the process of cloning and you will cut the vector with same restriction enzymes through which you have cut your target DNA sequence to be inserted into the vector.
3: You place the target gene into the vector and join or seal the gene with vector by using an enzyme called DNA ligase.
4: You introduce the vector with your target gene into a suitable host organism such as yeast or bacteria through the process of Transformation. In this process host organism takes up the vector containing your target gene and starts replicating the target DNA along with their own DNA and thus creating millions of copies of target gene .
5: In the last step, the DNA or target gene is isolated from host organism and purified and is ready to be used since its quantity has been enormously increased through the process of cloning.
The cloning is also called as recombinant DNA technology and is the main process that is being used in the production of insulin for diabetes patients. You can see below image for better understanding.
Hope it help!
Maltose is produced instantly when amylase reacts with starch.
Starch is a polysaccharide molecule made of glucose units. The chemical formula of the starch is written as (C₆H₁₀O₅)ₙ. The starch consists of amylose and amylopectin. The glucose units in this starch are linked with the help of two kinds of bonds α 1,4 glycosidic linkages and α 1,6 glycosidic linkages.
This starch molecule is first hydrolyzed into shorter polysaccharides, dextrins, and maltose with a help of an enzyme called amylase. The maltose can be further hydrolyzed into glucose units with the help of the maltase enzyme.
Therefore, the blank can be filled with maltose.

Answer:the villi of the intestine
Explanation:like the cristae of the mitochondria which increase the surface area for the production of ATP,the villi of the intestine acts similarly.
In animals, digested food pass from the stomach to the intestine. In the intestine , enzymes acts on the food. Absorption of food takes place there and there are some structures that facilitates it. The walls of the intestine have numerous foldings , alongside the presence of finger like projection called villi. Microvilli are also presence from the cell walls of the intestine . These projections increase the surface area for the absorbing of food .they brush against food in the intestine and promotes absorption of nutrients.
