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.
The correct answer is "near the midpoint of the cycle". Ovulation is part of the menstrual cycle in women, wherein this is the stage where unfertilized ova or ovules are being discharged from the ovaries of the woman, which was supposed to be fertilized by a male's sperm, but since you haven't had intercourse, you would still have menstruation.
