Question 1

What is the formula for calculating GC content?

Accepted Answer

GC Content (%) = [(Count of G + Count of C) / (Total Count of A + T + G + C)] * 100.

Question 2

Why does high GC content increase DNA melting temperature?

Accepted Answer

Guanine and Cytosine bind with three hydrogen bonds, whereas Adenine and Thymine bind with only two, requiring more thermal energy to denature.

Question 3

What is a typical GC content percentage in the human genome?

Accepted Answer

The average GC content of the human genome is approximately 41%.

Question 4

What is ideal GC content for PCR primers?

Accepted Answer

Optimal PCR primers typically have a GC content between 40% and 60% with a melting temperature between 52°C and 65°C.
