Summary Introduction

Introduction: An organism which has the characteristic feature to reproduce inside the living cell is called “virus”. They can survive without the host for a long period of time. When they infect the host cell they use the cell machinery of the host to reproduce. The size of the virus is extremely small and varies from 20 to 300 nm. The wide area of Earth is occupied by the viruses.

Answer to Problem 1TYU

Correct answer: The viral genome consists of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Hence, the correct answer is option (e).

Explanation of Solution

Reason for correct answer:

Viral genome can be DNA or RNA, but it cannot be both at the same time. The virus can have single stranded or double stranded genome. This makes the virus classified into four categories: ss DNA, ds DNA, ss RNA, and dsRNA. Viruses can possess only a single type of genome at a time. Thus, the virus consists of either DNA or RNA.

Option (e) is given as “DNA or RNA”.

The virus can have either “DNA or RNA” as its genome. Hence, the correct answer is option (e).

Reason for incorrect answer:

Option (a) is given as, “DNA”.

Some of the viruses also possess RNA as their genetic material. This means some of the viruses still carrying RNA as their genome. Hence, option (a) is incorrect.

Option (b) is given as, “RNA”.

There are a variety of species still exists which consist of DNA as their genome. This signifies that the variety of viruses are having different genetic material other than RNA Hence, option (b) is incorrect.

Option (c) is given as, “prions”.

A prion is an organism which does not affect by any radiation and the presence of either DNA or RNA was not found in them. Thus, such a structure cannot be considered as the genome. Hence, option (c) is incorrect.

Option (d) is given as, “DNA and RNA”.

Viruses cannot possess both DNA and RNA as their genome at the same time. They can have either DNA or RNA in their genome. Thus, both of these genomic materials cannot be considered as genetic material in viruses. Hence, option (d) is incorrect.

Hence, the options (a), (b), (c), and (d) are incorrect.

Conclusion

The genome of the virus can have either “DNA or RNA” at a time.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?   Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions.   Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
