Why do we classify viruses as obligatory intracellular
Expert Solution & Answer
Summary Introduction
To explain:
Why viruses are classified as obligatory intracellular parasites.
Introduction:
Viruses are small organisms which contain the DNA or RNA as its genetic materials. The genetic materials are composed of nucleic acid and proteins. It multiplies in all living cells, such as humans, animals, bacteria, and plants. Viroid and prion are diseases causing organisms that are composed of nucleic acids and proteins respectively.
Explanation of Solution
Viruses are considered as obligatory intracellular parasites because it multiplies by using synthesizing machinery of host cells to cause the synthesis of specialized elements that can transfer the viral genetic material and to other cells.
Conclusion
Viruses are obligate intracellular parasites that require living host cell for multiplication and metabolic activities.

However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

- From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?arrow_forwardWhat experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?arrow_forwardYou’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.arrow_forward
