DNA is a double stranded nucleic acid which forms a double-helix structure made up of two chains of nucleotides, quite similar to that of a twisty ladder. RNA is only made up of a single strand of amino acids and therefore only forms a single stranded helix structure.
Answer:
Endangered species can be described as the species of animals or plants which are at the verge of extinction. Scientists tend to recognize the importance of every species in an ecosystem and make the world aware of the species which might go extinct. Nowadays, governments and citizens of a country pay much more attention to protect the endangered species.
Although, the wolves were a threat to some ecosystems but scientific researches have shown that these organisms can be beneficial in a number of ways. Hence, measures should be taken to protect these species. However, we can introduce species of wolves where the number of preys is more so that the ecosystem can be balanced.
Answer:
True
Explanation:
Hydrophobicity is the aversion to the water of a molecule (or part of it). Amino acids with a hydrophobic R group (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan) <em>will fold with the R groups in the interior to avoid water. This behavior is one of the most important forces in protein folding. </em>You can see it exemplified in the image I added.
