Answer:
Control of both RNA splicing and chromatin remodeling control of RNA splicing.
Explanation:
RNA is present as genetic material but in case of some viruses only. RNA contains the nitrogenous base ( adenine, guanine, uracil and cytosine), oxyribose sugar and phosphate group.
The bacteria do not have well developed nucleus so no chromatin remodification occurs in case of bacteria. Bacteria is devoid of introns and contains only exons in its RNA structure. The splicing process is not required in case of bacteria.
Thus, the correct answer is option (4).
Answer:
According to the characteristics given and what the image shows, the species to which the frog corresponds is Bufo boreas.
Explanation:
Options for this question are:
- <em>Bufo marinus
.</em>
- <em> Litoria caerulea
.</em>
- <em>
</em><em>Bufo boreas.
</em>
- <em>
Acris crepitans.</em>
Bufo boreas is a species belonging to the family Bufonidae, very common in North America, constituting an anuro amphibian.
The appearance of B. boreas is that of a thickened and irregular skin, due to multiple warts found on its surface. Additionally it has a stripe or line in its dorsal region, which extends from the head to the tail.
These characteristics, together with the description given, make it possible to establish that B. boreas is the species that can be observed in the picture (see image).
