What is genetic engineering?

Back

Genetic engineering is the manipulation of the genetic material of organisms to alter their characteristics.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is primarily used for separating DNA fragments based on size.

Front

What type of mutation is a substitution?

Back

A substitution mutation is a type of mutation where one base pair in the DNA sequence is replaced by another.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotide base pairs are added into a DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation is when one or more nucleotide base pairs are removed from a DNA sequence.

Front

What is a translocation mutation?

Back

A translocation mutation involves the rearrangement of parts between nonhomologous chromosomes.

Front

What is the effect of a stop codon in translation?

Back

A stop codon signals the termination of protein synthesis, causing translation to stop.

Front

What is PCR (Polymerase Chain Reaction)?

Back

PCR is a technique used to amplify specific DNA sequences, making millions of copies of a particular segment.

Front

What is the role of DNA in genetic engineering?

Back

DNA serves as the blueprint for genetic engineering, allowing scientists to modify genes to achieve desired traits.

Front

What is the significance of DNA sequencing?

Back

DNA sequencing determines the exact order of nucleotides in a DNA molecule, which is crucial for understanding genetic information.
