The correct answer is option A. Carrying the genetic code and determining an organism's structure and function are the functions of DNA. It is the hereditary material in almost all other organisms. The information in a DNA is stored as codes that is composed of chemical bases.
A. multiply the chance that it will be a boy x the chance he will have PKU (1/2 x 1/4)
<span>B. chance of having PKU + chance of albinism </span>
<span>C. chance PKU x chance albinism</span>
Answer:
1 day.
Explanation:
From the given information:
The rate of mutation induced by RNA polymerase is:

Since the genome comprise of 19000 bp;
To complete a single replication, the viral cycle induce: 

However, in a single day; 10,000,000,000 viruses are reported to be replicated.
Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

Explanation:
Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
