Biotechnology and Genetic Engineering Concepts

The video introduces biotechnology, focusing on genetic engineering and gel electrophoresis. It explains how genetic engineering alters DNA using artificial methods and describes gel electrophoresis as a technique to analyze DNA fragments. The video covers applications like comparing DNA from crime scenes and paternity testing, highlighting the importance of DNA in heredity and identification.

What is the primary goal of biotechnology?

• To improve quality of life

• To eliminate diseases

• To create new species

• To increase food production

How does genetic engineering differ from traditional breeding?

• It uses natural selection

• It relies on environmental changes

• It is slower than traditional breeding

• It involves artificial DNA modification

What is the purpose of gel electrophoresis in genetic engineering?

• To replicate DNA strands

• To destroy unwanted DNA

• To create new DNA sequences

• To separate and analyze DNA fragments

What role do restriction enzymes play in gel electrophoresis?

• They visualize DNA fragments

• They bind DNA fragments together

• They cut DNA at specific sequences

• They replicate DNA

Why is an electrical current used in gel electrophoresis?

• To cool the DNA

• To heat the gel

• To move DNA fragments based on charge

• To solidify the gel

Which of the following is NOT an application of gel electrophoresis?

• Comparing DNA genomes

• Matching DNA from crime scenes

• Identifying genes

• Creating new DNA sequences

What is required to compare DNA from a crime scene?

• DNA from a suspect and a random person

• DNA from the crime scene, a suspect, and a random person

• DNA from the crime scene and a suspect

• DNA from the crime scene and a random person

In paternity testing, what is compared to determine the biological father?

• The child's DNA with the mother's DNA

• The child's DNA with the suspected father's DNA

• The child's DNA with both parents' DNA

• The child's DNA with a random person's DNA

How much DNA does a child inherit from each parent?

• 25% from each parent

• 50% from each parent

• 75% from each parent

• 100% from one parent

Why is a random person's DNA used in paternity testing?

• To confuse the results

• To ensure the child doesn't match randomly

• To provide a backup sample

• To verify the mother's identity
