11 Questions
What is the function of restriction enzymes in gene cloning and recombinant DNA technology?
Restriction enzymes are used to cut DNA at specific recognition sites, creating fragments with sticky ends that can be easily joined with other DNA fragments.
What role do DNA ligases play in genetic engineering?
DNA ligases play the role of genetic glue by catalyzing the joining of DNA fragments through the formation of phosphodiester bonds between the sugar phosphate backbones of adjacent DNA strands.
What is the primary responsibility of DNA polymerases in genetic engineering?
DNA polymerases are responsible for DNA replication, copying the genetic material during cell division. They are also used for processes like polymerase chain reaction (PCR) and DNA sequencing.
What is the significance of the single-stranded overhangs created by restriction enzymes?
The single-stranded overhangs created by restriction enzymes allow for the easy joining of DNA fragments with other DNA fragments.
What is the function of reverse transcriptases in genetic engineering?
Reverse transcriptases are used to create complementary DNA (cDNA) from RNA templates, a crucial step in many molecular biology techniques.
Restriction Enzymes (Endonucleases) - are used to cut DNA at specific recognition sites known as restriction sites - they cleave the DNA at these sites creating fragments with sticky ends single stranded overhangs that can be Easily joined with other DNA fragments - restriction enzymes are crucial for gene cloning and recombinant DNA technology after DNA has been cut by restriction enzymes DNA ligases - play the role of genetic glue - they catalyze the joining of DNA fragments by forming phosphodiester bonds between the sugar phosphate backbones of adjacent DNA strands - DNA ligases are essential for Creating recombinant DNA molecules DNA polymerases - are enzymes responsible for DNA replication copying the genetic material during cell division - in genetic engineering DNA polymerases are used for processes like polymerase Chain Reaction PCR which amplifies specific DNA sequences and DNA sequencing allowing researchers to read the genetic code Reverse Transcriptase’s - are used to creat.
