Which of the following statements about viruses Could be true? (Watch the wording carefully) A. Viruses are living because they can reproduce themselves. B. Viruses are not living because they don't evolve. C. Viruses are not living because they are ce ...
The prime directive of all organisms is to reproduce and survive and this also applies to viruses. Apparently, viruses are considered a nuisance to humans. Viruses – An Overview Virusespossess both living and non-living characteristics. The unique characteristic that differentiates viruses from other...
Poxviruses represent the family of viruses that are physically the largest viruses and that possess the largest genomes. Much of the poxvirus genome encodes gene products that serve to evade host immune responses, and that are not required for virus replication in tissue culture. Further, facile ...
Viruses belonging to the other three families, the Arenaviridae, Bunyaviridae, and Orthomyxoviridae, possess segmented genomes with two, three, and six to eight segments, respectively. Regardless of whether the genome is one RNA molecule or is segmented, the genomes of all (−)RNA viruses ...
Human T-lymphotropic viruses (HTLVs) are deltaretroviruses that possess a distinctive capacity to transform primary T cells in vivo and in vitro, despite the absence of a proto-oncogene in their genome. HTLV-1, the most prevalent of the HTLVs, has infected ~10 million individuals worldwide,...
Nevertheless, apparently viruses possess an inherent capacity that enables them to cross this invisible dividing line in order to link up with the ATP molecule through which they sustain their activities. The following presents a review of these issues with regard to microbiology, biochemistry and ...
I. Molluscs possess cellular level of organisation. II. Arthropods are true coelomates. III. Platyhelminthes are pseudocoelomates. IV. Ctenophores have bilateral symmetry. Choose the correct option. View Solution Which of the following statements are correct about penicillin?
In an alignment of sequences of human, avian, swine and bat IVs we found that almost all viruses do possess the serine resi dues 269 and 392 (Table S3), which were described as phosphorylation sites of RSK1, the downstream kinase of MEK/ERK [22]. This high level of conservation ...
Cancer cells that are pluripotent and have self-renewal capacity and, thus, possess stem-cell-like characteristics. Neuroendocrine tumours Tumours that arise from neuroendocrine cells, which are specialized cells that often produce hormones under neuronal control. T cell anergy A state in which T cell...
