6. Annealing Temperature (Ta): • The primer melting temperature is the estimate of the DNA-DNA hybrid stability and critical in determining the annealing temperature. Depends directly on length and GC composition of the primers. . • Too high Ta - produce insufficient primer-template hybridization. • Too low Ta - lead to non-specific products caused by a high number of base pair mismatches. 47/49 Now you should be able to answer the following questions >> How the amplification will be done? » How you will determine your target sequence? >> How the amplification will be specific for certain segment? >> What are the requirements to carry PCR?

A single strand of DNA, 24 nucleotides long, with the sequence 5'-TTTCCCgggAAAgggTTTAAAggg-3' is in a test tube. (Note that G's are shown in lowercase, so that your eye can better distinguish them from C's) Other than the appropriate buffer solution, what else needs to go in the test tube to so that we end up with a piece of double stranded DNA, 24 base pairs long, with the above sequence comprising one of the two strands?
What is the role of alcohol in extracting DNA? 1.DNA is a polar molecule with an overall negative charge, and as such is not soluble in alcohol, and therefore precipitates. 2.DNA is a polar molecule with an overall positive charge, and as such is not soluble in alcohol, and therefore precipitates. 3.DNA is a non polar molecule with an overall negative change, and as such is soluble in alcohol, and therefore precipitates. 4.DNA is a polar molecule with an overall positive change, and as such is soluble in alcohol, and therefore precipitates.
