Question

All of the following techniques are correctly matched with their purpose, except one, which one is FALSE?

a) Single Gene DNA Sequencing: Determine the exact sequence of a 1000 nucleotide piece of DNA and identify variations in that specific region of the DNA
b) Gel Electrophoresis: Separate DNA molecules based on their size and can help identify insertions and deletions
c) PCR: Make many full-length copies of the entire set of chromosomes in a human
d) SNP Chip: Identify thousands of single nucleotide polymorphisms at a time using hybridization
e) Whole Genome Sequencing: Determine the exact sequence of all the nucleotides for all DNA in a person to help identify any sequence variations

Answer 1

PCR does not make full-length copies of the entire set of chromosomes in a human. The other techniques listed are correctly matched with their purposes.

Step-by-step explanation:

Among the techniques listed, the one that is FALSE is c) PCR: Make many full-length copies of the entire set of chromosomes in a human. PCR (Polymerase Chain Reaction) is a method used to amplify a specific segment of DNA, not the entire set of chromosomes. It is commonly used in DNA sequencing, and it enables the generation of many copies of a particular DNA segment for further analysis.

The other techniques mentioned are all correctly matched with their purposes:

1. a) Single Gene DNA Sequencing: This technique is used to determine the exact sequence of a specific region of DNA, as well as identify any variations in that region.
2. b) Gel Electrophoresis: Gel electrophoresis is used to separate DNA molecules based on their size, allowing for the detection of insertions, deletions, and other variations.
3. d) SNP Chip: SNP (Single Nucleotide Polymorphism) chip is used to identify thousands of single nucleotide polymorphisms simultaneously, aiding in the study of genetic variations.
4. e) Whole Genome Sequencing: This technique involves determining the exact sequence of all nucleotides in an individual's DNA, helping to identify any sequence variations across the entire genome.
