<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:
b. <em>Homo neanderthalensis</em>
Explanation:
<em>Homo neanderthalensis </em>are extinct species of the Homo genus which lived in Eurasia until 40000 years ago. They initially lived in Europe and then migrated to Central and Southwest Asia. Compared to modern humans, they had shorter legs and bigger bodies.
They have been known to construct huts out of mammoth bones. Archaelogists discovered a Neanderthal hut structure made of mammoth bone which is considered to be 44000 years old. This structure was 26 feet wide and mostly used for domestic purposes. Previously <em>Homo neanderthalensis </em>were considered primitive creatures who lived in natural caves but after this discovery it has been accepted that they were also advanced.
