Chargaff’s rule, which one of the answer choices would be complementary to this strand? ** TATGCA
The Lewis Theory describes a base as a compound that donates an electron pair. By donating the electron pair there is a covalent bond.
An acid base pair which differ from each other by a single proton(H+ ion) is called a conjugate pair. Eg. Acid Base HCl Cl- NH3 NH4+ H2O H3O+
HCL is the conjugate acid pair of Cl. And Cl is the conjugate base pair of HCl.
NH3 is a bronsted base. It has a lone pair.
An acid accepts an electron pair from a base.
base pairing rules
Adenine
Erwin Chargaff
A and T go together C and G go together
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base pairing rules means that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
The percentage of the nucleotide adenine = the percentage of thymine. The percentage of guanine = the percentage of cytosine.
Guanine
c bonds to g and t bonds to a
The base pairing-rules for DNA are that, only the Nitrogen Bases of DNA which are; Adenine "A"-which only pairs with-Thymine "T", and Cytosine "C"-which only pairs with-Guanine "G" can only pair to one another within that sequence.Posted By; JoelBaum24

Chargaff's rules stated that the number of adenine units in a DNA segment were equal to the number of thymine units.
Every guanine has to pair with cytosine and every adenine has to pair with a thymine. If this wasn't a rule then DNA can't replicate itself and mutations would occur.
