What is the significance of a recombinant plasmid?
drek231 [11]

Answer:

recombinant DNA

A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA

Explanation:

Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.

Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.

This single DNA is known as Recombinant DNA

Reactant product
gogolik [260]

Answer:

4 grams

Explanation:

If in an experiment, we have 4g of reactants, the mass of the products will also be 4g.

This is in compliance with the law of conservation of mass in a chemical reaction.

According to this law,

  "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

If:

      A + B →  C

         4g        4g

mass of A and B must be equal to the mass of the product according to the law of conservation of mass.
