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 diagram of a prokaryotic replication fork is shown. As in class, RNA primers are represented by a wavy line and DNA represented by a straight line. From the list below pick all the statements that are TRUE of this replication fork. (Multiple answers possible)
A.Primer sequences are not correct.
B. DNA being synthesized is not complementary and antiparallel to the template.
C. Direction of DNA synthesis is not correct (not 5' to 3').
D. At least one protein in the diagram is mislabeled.
