Question

Use human genetics to answer the following questions (please print)

1. (10 pts) Given this equation D_t = (1-r)^t x D₀  we can see that D is changing every generation.

What is D?

What is r?

What is the range for D?

What is happening to D?

What determines the speed at which D changes?

What kind of an event happened to cause a D close to the upper range?

2. (10) How much of the human genome is transcribed? Give a rough percentage…. What does that mean?

Answer 1

1. For the first part, please give some reference as to what concept of genetics is the equation related to. Not enough information is provided so as to conclusively deduce the equation.
2. Around 2% of the human genome is transcribed. Rest 98% is either non- coding for any RNA or we do not know its function yet. Protein coding genes account for approximately 1.5% of this 2% transcribed region of the genome. Rest 0.5% is coding tRNA, rRNA, LINES, SINES and other small and regulatory RNAs. This means that we do not yet know about a lot of our genome. A whole lot has to be studied. We know genes whose functions are yet to be disclosed. The large chunk of DNA about which we do not know a lot (98%) is being studied and its roles in gene regulation are important for cell survivability.
