-
Polymerase Chain Reaction (PCR)
-
Microarray Analysis
-
Southern Blotting
A
Correct answer
Explanation
Karyotyping is a genetic testing technique that analyzes the number and structure of chromosomes to identify chromosomal abnormalities, such as deletions, duplications, or translocations.
Which molecular technique is commonly used to extract and analyze DNA from fossils?
-
Polymerase Chain Reaction (PCR)
-
Gel Electrophoresis
-
DNA Microarray
-
DNA Sequencing
A
Correct answer
Explanation
Polymerase Chain Reaction (PCR) is a molecular technique used to amplify specific regions of DNA. In molecular paleontology, PCR is employed to extract and amplify DNA fragments from ancient fossils, allowing for further analysis and sequencing.
