DNA is found in what two organelles  

• Nucleus and Ribosomes
• Ribosomes and Mitochondria 
• Nucleolus and Golgi Body
• Nucleus and Mitochondria

Mitochondrial DNA is different from nuclear DNA because

• it is inherited only from the mother
• It is inherited only from the father
• It is double helix in shape
• It is not useful in forensic science

The male determines the sex of the child

• True
• False
• sometimes

This type of DNA testing examines the number of repeats that occur at a particular locus

• karyotype
• PCR
• RLFP
• STR

This technique is used to copy target segments of DNA

• Gel electrophoresis

• PCR

• RLFP

• STR
