Document Summary
Dna profiling (multiple short answers) - list procedure etc. What is the effect if you have a missense mutation. Then you end up many copies of the dna. Inheriting genetic factors increases risk but does not guarantee disease. You start with 2 original strands, but you end up with parental(original) strand and a complementary strand a. b. Revise frameshift there are many "tricky" questions on it i. ii. Imagine, dna[atgt cag tta]; a changes to t, and t is added after atg. Now, dna{atg tca gtt]; now everything has changed! ; the same occurs when deletion occurs --> this is frameshift a. This one is only for single nucleotide a. b. Outside of dna is the backbone, it has phosphate & sugar. Nucleotide is the ladder (inside) - nitrogenous base pairs. And initially it is 1/4 for any child, and with addition of boy constrain makes it 1/8 because there is a 50% chance of boy/girl [1/4 * 1/2]
