1. What does RFLP stand for and what is it primarily used for?
2. Who developed DNA fingerprinting?
3. What is the prokaryotic promoter at the -35 element?

1. Restriction Fragment Length Polymorphisms, they are used as genetic markers for DNA cutting
2. Alec Jeffreys
3. TTGACA

3' TACCATATACCGACT 5'

Label the following point mutations:

1.

3' TACCCATATACCGACT 5'
5' ATG GGT ATA TGG CTG A 3'

2.

3' TACCATATACCGCCT 5'
5' ATG GTA TAT GGC GGA 3'

3.

3' TACCATAGACCGACT 5'
5' ATG GTA TCT GGC TGA 3'

1. conservative missense 

2. a stop codon mutation? idk what its called maybe antimissense

3. non conservative missense

A scientist takes a survey of the 3562 pop. group to find that the group suffers from malaria. The population also suffers from sickle cell anemia, as the recessive allele for sickle cell has a frequency of 46% in the population (sickle cell is a autosomal recessive disease).

1. How much (%) of the population actually has sickle cell anemia?

2. How many people have resistance to malaria?

3. How many people are immune to malaria and are free from sickle cell anemia?
