PCR is a technique used to amplify trace amounts of ______ to be used in scientific and forensic analyses.Multiple choice question.stem cellsDNAproteinRNA

Break Down the Problem

1. Identify what PCR stands for and its primary function.
2. Understand the materials that PCR amplifies in scientific and forensic analyses.

Relevant Concepts

• PCR (Polymerase Chain Reaction) is a molecular biology technique used to amplify specific segments of DNA.
• The technique involves repeated cycles of denaturation, annealing, and extension, allowing for the exponential increase of the DNA segment of interest.

Analysis and Detail

1. Trace Amounts: PCR is specifically designed to work with very small quantities of DNA.
2. Applications: It is widely used in various fields, including genetics, forensics, and medical diagnostics, making it crucial for amplifying DNA for testing and analysis.

Verify and Summarize

• Among the given options—stem cells, DNA, protein, and RNA—DNA is the most pertinent as PCR primarily targets and amplifies DNA sequences.

Final Answer

PCR is a technique used to amplify trace amounts of DNA to be used in scientific and forensic analyses.
