(a) What do 'Y' and 'B' stand for in 'YAC' and 'BAC' used in Human Genome Project (HGP) ?
Mention their role in the project.
(b) Write the percentage of the total human genome that codes for proteins and the percentage of
discovered genes whose functions are known as observed during HGP.
(c) Expand 'SNPs' identified by scientists in HGP. (3 marks)
(a) Y = Yeast;
B = Bacterial
Role in Human Genome Project. They are used as vectors for cloning of foreign DNA.
(b) Less than 2% of the genome codes for proteins.
Percentage of discovered genes whose functions are known as observed during HGP is less
(c) SNPs - Single Nucleotide Polymorphism
