<span>siRNA guides the RISC that cleaves the target mRNA. siRNA binds to its target mRNA due to its complementarity.</span> <span>Small interfering RNA (siRNA) has a function in RNA interference, which means it causes gene silencing through repression of transcription. siRNA together with some proteins (like Argonaute) form the RISC. When siRNA recognize the target mRNA it causes degradation of mRNA and thus silencing the gene that encodes that mRNA.</span>
Answer:
C). Buffers
Explanation:
The given analogy can best be completed with 'buffers' as it similarly compares with the 'solution pH' like the comparison between 'shock absorbers' and 'vehicle movement.' <u><em>Like the 'shock absorbers' function to help in improvising the vehicle movement and ride quality by lowering the effect reverberations of traveling on a rough platform, similarly, the 'buffers' help in regulating the 'pH of a solution.</em></u>' Thus, <u>option C</u> is the correct answer.
Answer:
B)attach specifically to host cell receptors
Explanation:
Viral spikes are one of the envelope proteins. These proteins are coded for by viral genes. Viral spikes project from the envelope surface. They are also called peplomers. One of the functions of these spikes is to specifically interact with the receptors present on the surface of the host cell to mediate the attachment of the virus to the host cell surface. Viral spikes and the host cell surface receptors are complementary to allow their specific binding. For example, the spike protein of the SARS-coronavirus bind specifically to the human host cell receptor ACE2.
Isotonic cells stay the same hypertonic the cells shrink and hypotonic the cells grow or swell
