1. List the names of the 9 hydrophobic "R" groups. a) What are the two most common atoms across these 9 "R" groups? b) Look at the hydrophilic side chains. Besides carbon & hydrogen, what are the two the most common atoms in this group? 2. On the chart, locate the two acidic side chains. They both have a carboxylic acid functional group. What charge do these side chains have? a) On the chart, locate the two basic side chains. They both have an amino functional group. What charge do these side chains have? b) Locate cysteine on the chemical properties circle. What atom is found in this side chain that is not found in most of the others (except methionine)?
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.
