What is gel electrophoresis?

Back

A laboratory technique used to separate DNA, RNA, or proteins based on their size and charge.

Front

What does a banding pattern in gel electrophoresis indicate?

Back

The presence and size of specific DNA fragments in a sample.

Front

What is the purpose of Polymerase Chain Reaction (PCR)?

Back

To amplify a small sample of DNA to sufficient levels for analysis.

Front

What does it mean if a DNA sample has a band pattern identical to a control sample?

Back

The DNA sample is identical to the control.

Front

What information can gel electrophoresis provide in genetic engineering?

Back

It can show the presence and size of DNA fragments containing the introduced gene.

Front

What is the role of DNA in genetic engineering?

Back

DNA carries the genetic information that can be modified to alter traits in organisms.

Front

What is a genetic disorder?

Back

A disease caused by abnormalities in an individual's DNA.

Front

What is the significance of detecting specific genes in genetic research?

Back

It helps identify genetic disorders and understand gene functions.

Front

What is the difference between DNA sequencing and gel electrophoresis?

Back

DNA sequencing determines the exact order of nucleotides, while gel electrophoresis separates DNA fragments by size.

Front

What is contamination in a DNA sample?

Back

The presence of unwanted DNA or substances that can affect the results of an experiment.
