Which one of the following pairs of nitrogenous bases of nucleic acids, is wrongly matched with the category against it?

Name the nitrogen base that replaces thymine in RNA.

While analysing the DNA of an organism a total number of 5386 nucleotides were found out of which the proportion of different bases were: Adenine = 29%, Guanine = 17%, Cytosine = 32%, Thymine = 17%. Considering the Chargaffs rule it can be concluded that.

he Chargoff’s rule says that DNA contains equal amounts of guanine and cytosine and also equimolar amounts of adenine and thymine as: G= C and A= T Does Chargoff’s rule imply that equal amounts of guanine and adenine are present in DNA?

he Chargoff’s rule says that DNA contains equal amounts of guanine and cytosine and also equimolar amounts of adenine and thymine as: G= C and A= T Does Chargoff’s rule imply that the sum of purine residues equals the sum of pyrimidine residues i.e. does A+G =C+T ?

A biologist studying the genetic code is interested to know the number of possible arrangements of 12 molecules in a chain. The chain contains 4 different molecules represented by the initials A (for Adenine), C (for Cytosine). G (for Guanine) and T (for Thymine) and 3 molecules of each kind. How many different such arrangements are possible in all ?
