When we cut a gene out of a strand of DNA and paste it into another strand of DNA, we have:
|
|
Ribosomes.
|
|
|
Message DNA or RNA.
|
|
|
Lycopene.
|
|
|
Recombinant DNA.
|
Explanation:
Detailed explanation-1: -The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragments at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends.
Detailed explanation-2: -The process of DNA ligation occurs when DNA strands are covalently joined, end-to-end through the action of an enzyme called DNA ligase. Sticky-ended molecules with complementary overhanging sequences are said to have compatible ends, which facilitate their joining to form recombinant DNA.
