DNA Profiling and Ethical Concerns

The video tutorial covers DNA profiling, focusing on electrophoresis and its application in forensic science. It explains the process of DNA sequencing, the use of electropherograms, and the role of short tandem repeats (STRs) in genetic comparison. The tutorial also discusses ethical and economic considerations in genetics, such as privacy concerns and the potential for designer babies.

What is the primary purpose of DNA profiling?

• To create identical copies of DNA

• To identify unique genetic markers in individuals

• To alter genetic sequences for medical purposes

• To map the entire human genome

How does gel electrophoresis separate DNA fragments?

• By their weight

• By their length

• By their color

• By their charge

What is the role of restriction enzymes in DNA profiling?

• To amplify DNA sequences

• To cut DNA at specific sequences

• To sequence the entire genome

• To label DNA with fluorescent dyes

What technological advancement allows for faster DNA sequencing?

• Restriction enzyme cutting

• PCR amplification

• Electropherograms

• Gel electrophoresis

What are STRs and how are they used in DNA profiling?

• Short Tandem Repeats used to identify genetic similarities

• Single Tandem Repeats used to sequence genomes

• Short Tandem Repeats used to amplify DNA

• Single Tandem Repeats used to cut DNA

How can DNA sequence comparison be used in paternity testing?

• By matching the entire genome

• By comparing the number of specific repeats

• By identifying unique mutations

• By sequencing mitochondrial DNA

What is a potential ethical issue with DNA profiling?

• It can lead to the creation of designer babies

• It is too expensive for widespread use

• It cannot be used in forensic science

• It is not accurate enough for paternity testing

How might life insurance companies misuse genetic information?

• By sharing it with medical researchers

• By using it to improve healthcare

• By offering lower premiums to everyone

• By denying coverage based on genetic predispositions

What is a cultural concern related to DNA profiling?

• It is too complex for the general public

• It is not accepted by all cultures

• It may infringe on individual privacy

• It can lead to cultural homogenization

What is a potential economic issue with DNA sequencing?

• It requires expensive equipment and resources

• It is too cheap to be profitable

• It is not useful for medical research

• It cannot be automated
