Nucleotides polymerize via condensation reactions. The reaction forms a new covalent bond—a phosphodiester linkage, or a phospho
Finger [1]

Answer:

The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide

Explanation:

The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.

The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.

The phosphodiester bond binds a C3` with a C5` in both DNA and RNA

          (base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2   ------>

------>   (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2  

During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.

A gas occupies a volume of 72 ml at 400 k and 800 torr. if the temperature drops to 200 k and the pressure changes to 400 torr,
satela [25.4K]
We are tasked to solve for the volume of the gas that occupies when pressure and temperature changes to 400 Torr and 200 Kelvin from Torr and 400 Kelvin. We can use ideal gas law assuming constant gas composition and close system. The solution is shown below:
P1V1 / T1 = P2V2 / T2
V2 = P1V1T2 / T1P2
V2 = 800*72*200 / 400*400
V2 = 72 ml

The answer for the volume is 72 ml.
