What group is attached to the pyrimidine ring in thymine and is not present in uracil?

Nucleotides contain one or more phosphate groups that are usually attached to the:

‘AMP’ is used to refer to

Inside our cells, free nucleotides are almost always associated with

Humans typically recycle approximately of ATP each day.

Nucleoside triphosphates are useful for energy transfer because the phosphoanhydride bonds are relatively .

Nucleoside triphosphates carry energy in the form of

The major carrier of energy in the cell is:

By convention, the sequence of nucleotide residues in a nucleic acid is written starting with the end.

Chargaff’s rules state that:

The Watson and Crick model of a double-helical structure for DNA was based, in part, on evidence from

Knowledge about the tautomeric forms of the bases of nucleic acids is needed
