As far as I know, the polar sugar-phosphate backbones of each strand form the helical scaffold, with the nitrogenous bases in the interior of the molecule, their planes nearly perpendicular to the helical axis. However, I cannot sure that it always does. I am curious that there are some exceptional cases.
carbon 1
The four nitrogenous bases that can make up a nucleotide are adenine (A), thymine (T), guanine (G), and cytosine (C). A always pairs with T, and G always pairs with C in DNA. In RNA, thymine is replaced by uracil (U).
The structure of DNA contains nucleotides, which are made up of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The nucleotides are arranged in a double helix formation, with the nitrogenous bases pairing specifically (A with T, C with G) to form the genetic code.
In DNA, the nitrogenous base pairs are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs are essential for maintaining the DNA double helix structure and are crucial for genetic information storage and replication.
The nitrogenous base, Cytosine, pairs with the nitrogenous base, Guanine.In DNA:Cytosine - GuanineAdenine - ThymineIn RNA:Cytosine - GuanineAdenine - Uracil
The diagonals of a square are always perpendicular.
A rectangle always has perpendicular sides.
A rhombus has 4 equal sides and the diagonals are always perpendicular
In a kite geometric shape, the diagonals are always perpendicular.
Not always.
The diagonals of a rectangle are never perpendicular but the diagonals of a square are perpendicular
Yes they always do! They are not Perpendicular if they don't.
The negative reciprocal of the slope of the line to which it is perpendicular.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
yes
perpendicular
No.
