Concept explainers

Nucleotides

It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Nucleic Acids

Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

A student was asked to draw the structure of the amino acids serine (R group is -CH₂OH) and glycine (R group is -H) linked by a peptide bond. The student was asked to place glycine at the N terminus and serine at the C terminus, label the peptide bond, and label the N- and C-termini. The student's drawing is shown below. Which of the following errors need to be corrected in the student’s drawing? Check all that apply. Don’t get overwhelmed by the number of options; just consider them one at a time.

[Image: Diagram of the peptide bond between glycine and serine]

- **Peptide Bond**: The peptide bond is indicated in the drawing between the carbon and nitrogen of the amino acids.

- **N Terminus and C Terminus**: The drawing includes labels for the N terminus (left) and C terminus (right).

Options for correction:
- [ ] The nitrogen flanking the peptide bond should be connected to hydrogen via a single bond as opposed to oxygen via a double bond
- [ ] The positions of the N and C flanking the peptide bond should be swapped
- [ ] The labels on the N and C termini need to be swapped
- [ ] A positive charge should be added to the N terminus
- [ ] The alpha carbon of glycine is missing a proton
- [ ] The peptide bond should be shifted one bond to the right
- [ ] The positions of glycine and serine should be reversed
- [ ] The alpha carbon of serine is missing a proton
- [ ] The carbon next to the peptide bond should be connected to oxygen via a double bond as opposed to hydrogen via a single bond
- [ ] A negative charge should be added to the C terminus

A beginning genetics student is attempting to complete an assignment to draw a base pair from a DNA molecule. The drawing is incomplete, and the student does not know how to finish. He asks for your advice. The assignment sheet shows that the drawing is to contain three hydrogen bonds, a purine, and a pyrimidine. From your knowledge of the pairing rules and the number of hydrogen bonds in A/T and G/C base pairs, what base pair do you help the student draw?

Note: for simplicitys sake, analyze only this one strand of the DNA double helix, reading from left to right, so you will only be analyzing three of the six reading frames shown in Figure 19.4.
