Question

Quizplus · Accepted Answer

Electrophoresis is the technique that separates DNA fragments by size by using an electric field to move the negatively charged DNA through a gel matrix.

Answer: A
 Polymerase chain reaction (PCR) is a technique used to amplify a specific section of DNA, allowing for large amounts of identical DNA to be produced from a small sample.

Answer: C
 DNA sequencing is the process of determining the precise order of nucleotides in a DNA molecule.

Answer: D
 DNA profiling is a forensic technique used to identify individuals based on their unique DNA profile, which is generated by analyzing specific regions of their DNA.

Answer: F
 A probe is a small piece of DNA or RNA that is designed to bind to a specific target sequence, allowing for the identification or detection of that sequence. It is often used in molecular biology techniques such as DNA hybridization and Southern blotting.

Answer: G
 Transgenic refers to an organism that has been genetically modified by the insertion of one or more genes from another species, typically for the purpose of introducing a desirable trait or characteristic.
