Answer:
Explanation:
B) The pentose in the hairpin adopts only the C-3\' endo pucker conformation.
C) The hairpin adopts a right-handed helix with a diameter of 26 Å .
D) The hairpin contains G:C, A:U, and sometimes G:U base pairs.
DNA and RNA are both nucleic acids. Aside the structural difference of DNA being double stranded and RNA being single stranded, in DNA, the nucleotide bases adenine (A) is paired with thymine (T); while cytosine (C) is paired with guanine (G); howerver in RNA, thymine is replaced with uracil.; thus in RNA, the base pairs are - A:U and G:C
RNA however sometimes take on a dynamic structure, called the wobble case pair where guanine and uracil pair - G:U.
The diameter of RNA is 26 Å, while that of DNA is is 20 Å
The ribose in RNA with a helical structure has a C3’ endo conformation.
If we were to differentiate anthroprocentric and biocentric views of the environment you could say that anthroprocentric is more holistic than biocentric. They consider the importance of the environment to human beings. Biocentric sees humans as an individual part of the environment.
Also Biocentric views tend to focus more on biotic factors (living things) and anthroprocentric veer towards the abiotic factors (non-living things).
Answer:
The correct answer is would be - geographic isolation.
Explanation:
The geographic isolation is also known as the speciation in which biological species experience genetic changes and on the basis of the genetic changes that experienced this separated with other organisms of the species.
It is physical separation or speciation of the biological organisms on the basis of geographical barriers of two population of the same species that keep them from interbreeding and reproducing.
Thus, the correct answer is - geographical barriers.
