What is the function of DNA polymerase in a polymerase chain reaction?

Answer 1

Invented by Kary Mullis in 1983, the polymerase chain reaction (PCR) has grown to become a core technology in modern genetics. In genetic engineering PCR is typically used to amplify a marker for diagnostic applications or a gene of interest for insertion into an expression vector.

Answer 2

Gel electrophoresis in genetic engineering is separate fragments of DNA by their length and electrical charge. Transgenic bacteria have been suicide genes that cause them to self destruct when the job for which they are engineered has been accomplished.

Answer 3

It adds nucleotides to the denatured single stranded template DNA strand.

Answer 4

PCR (polymerase chain reaction) is used to amplify the DNA or gene of interest in a test tube (in vitro or lab environment)
