Question 1

The 6 important goals of HGP are

Answer 1

• Identify all the approximately 20,000-25,000 genes
• Determine the sequences of the 3 billion chemical bp
• Store this info in databases
• Improve tools for data analysis
• Transfer related tech to other sectors, such as industries
• Address ELSI that may arise from the project

Question 2

Why did Mendel choose garden pea for his experiments?

Answer 2

• Pea flowers are bisexual so they can be self pollinated and also cross pollinated by emasculation.
• Many contrasting characters are found which are easily identifiable.
• They are easy to cultivate.
• They have a short lifespan.

Question 6

Salient features of genetic code

Answer 6

• The codon is triplet. 61 codons code for amino acids, 3 are stop codons
• The code is degenerate.
• The codon is read in mRNA in a continuous fashion.
• The codon is nearly universal.
• AUG has dual functions. Codes for Methionine and acts as initiator codon.
• UAA, UAG and UGA are the stop codons.
