Q

How does DNA replication occur?

A

• Double helix DNA unwinds
• Weak hydrogen bonds break
• Two DNA strands unzip/ separate
• Each original DNA strand severs as a template to form a new strand

• Complementary strands form
• The result is two genetically identical DNA molecules

Q

What are the uses of DNA profiles?

A

• Diagnosis of inherent Disorders
• Developing cures for inherent disorders

• Biological Evidence
• Identification of Relatives

17
Q

Why is DNA profiling sometimes unreliable?

A

• DNA profile may not be unique to an individual.
• May not follow uniform testing standards and quality controls.
• Human error could lead to false results.
• DNA profiling is expensive
• HIV / AIDS

18
Q

What are Somatic Cells

A

Body cells

19
Q

What are Gametes?

A

Sex Cells

20
Q

What is a DNA Profile?

A

•DNA Profiling is a method of identifying an individual by comparing his/her DNA Proflie with another known DNA “Fingerprint”.

21
Q

What are some debates around DNA profiling?

A

• Small piece of DNA is analyzed, so a DNA profile may not be unique to an individual.

• May not follow uniform testing standards

• Human error

• DNA profiling is expensive, so people might not be able to defend themselves against charges based on DNA evidence.

22
Q

Why is DNA Replication necessary?

A

° Produce another molecule that is exactly the same
° Pass on Genetic code
° Needed for Cellular Replication

23
Q

Gonosome

A

° Sex chromosomes ( Determine your sex/ gender )

24
Q

The division of cytoplasm after nuclear division

A

° Cytokinesis
