Matriculation number
Question 1 [2.5 marks]
a. Cubs of tamed mothers were raised by aggressive mothers and cubs of aggressive mothers were raised by tamed mothers only to prove that the mother’s behaviour does not influence that of the cubs’. Another method used was when they took the embryos of the aggressive mothers and planted it to tame mothers and they got the same results. It shows that You cant change the gene of aggressiveness and it is preserve until the next generation
b.
i) Haemoglobin – a gene that is useless will eventually be lost and the mutation will erase it.
ii) Anti-free protein – gene mutation; the fishes needed this to survive the freezing waters of their environment
c. What DNA tells us is that our lineage goes back several years ago. What DNA can’t tell us is where and when traits that distinguish us such bipedality first emerge.

b. & c
Extracted DNA
Primer 1 - primers attach to sites in the DNA strands that are at either end of the segment you want to copy.
Primer 2- that will attach to the second site
Nucleotides are the A’s c’s g’s and t’s that make up the DNA code
DNA Polymerase molecules act like tiny machines that read the DNA code and then attach the matching nucleotides to t create DNA copies
