Determine the most stable secondary structure that can be formed from the RNA oligonucleotide 5’-GAGUGCGCGAGCCUCU-3’. Consider only Watson-Crick base-pairing

Answers

Answer 1
Answer: Complementarity is achieved through interactions between nucleobases. In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). RNA secondary structure is achieved when two regions of one strand base pair and form a double helix.
Respecting the rule of complementarity and base-pairing, some of the bases will pair and some will not, as it can be seen on the image. The stability depends on helix length, base composition, and the number of mismatches.

What is genetic variation?

Genetic variation refers to differences in the genetic material (DNA) among individuals within a species. This can arise due to several mechanisms, including mutation, recombination, and genetic drift. Genetic variation provides the basis for evolution by natural selection, as it allows for populations to adapt to changing environments and helps to ensure the survival of the species over time.

Genetic variation can also play a role in disease resistance, as some individuals may carry genetic variations that protect them from certain diseases. Additionally, genetic variation can impact physical and behavioral traits, such as eye color, height, and intelligence.

Nope. A is a correct answer. A mouse simply learns how to avoid a trap, there is no genetic change responsible for that
