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

A template DNA strand (top) and a coding DNA strand (bottom) are shown below:

3' TACCATATACCGACT 5'
5' ATGGTATATGGCTGA 3'

Label the following point mutations:

1.

3' TACCCATATACCGACT 5'
5' ATGGGTATATGGCTGA 3'

2.

3' TACCATATACCGCCT 5'
5' ATGGTATATGGCGGA 3'

3.

3' TACCATAGACCGACT 5'
5' ATGGTATCTGGCTGA 3'

1. conservative missense 
2. a stop codon mutation? idk what its called maybe antimissense
3. non conservative missense 
I thinks that's what you meant?

For #1, I was looking for frameshift. The other two look good, your turn!

A newly found isolated population in South America which theoretically is in Hardy-Weinberg equilibrium has been discovered. 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?

All correct, though for 2 and 3 I was looking for a number of people not a percent, sorry bout that. Your turn!

List the three steps in post-transcriptional modification, and, if applicable, which end of the mRNA is altered by them.

1. Splicing of all the introns 2. Polyadenylation on the 3' end 3. Adding of the 5' cap
