<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:
The answer is freedom.
Explanation:
All the others do not evoke positive feelings, but freedom does. it also says 'the answer is freedom' at the end of your post!
The first answer is the correct one. Osmosis is only water and diffusion is everything else across a semi-permeable membrane.
The importance of fat in the diets of our ancestors was mainly a result of its energy-storing properties.
Option B
Explanation:
Earlier ancestors or say, hominids ancestor were at the inception of the evolutionary world developed a trend on eating whatever they could find. The ancestors are believed to be scavengers rather than hunters as the evolutionary and nutrition biology suggests.
They had to travel and work for the food and as they were scavengers, it was not guaranteed to have food on a daily basis, so the fat has energy storing properties and for which its importance was realized in the diet. Later when they became hunters, protein became more important in their diet.
