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
NH3 with N in top of the (teraedral) pyramid (3 H at base)
DNA contains 4 nitrogenous bases that pair with each other. Thymine always pairs with Adenine, and Cytosine always bonds with Guanine. DNA also contains the sugar deoxyribose.
The nitrogenous base, Cytosine, pairs with the nitrogenous base, Guanine.In DNA:Cytosine - GuanineAdenine - ThymineIn RNA:Cytosine - GuanineAdenine - Uracil
The pairing sequence is: (A) Adenine - (T) Thymine (C) Cytosine-(G) Guainine
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
how can you create a memory device to help you remember how the nitrogenous bases are always paired
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.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
The negative reciprocal of the slope of the line to which it is perpendicular.
