(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.

Solution

(a) Y stands for Yeast in YAC (Yeast artificial chromosome) and
B stands for Bacteria in BAC (Bacterial artificial chromosome)
YAC and BAC are used as vectors in the Human genome project.
(b) Less than 2% of the genome codes for proteins. 21.4% is discovered genes whose functions are known as observed during HGP.
(c) SNP stands for Single Nucleotide Polymorphism.
