Shown below is a partial gene map for Drosophila melanogaster. In Drosophila, vermillion e are recessive (v) to red eyes (V) and the gene resides on chromosome 1; dumpy wings (d) recessive to normal wings (D); and speckled body (s) is recessive to normal body (S). The dur wing gene and the speckle body gene are linked on chromosome 2 and have 7 map units separa them. Assume that chromosome 1 and 2 are autosomal chromosomes and that there are no knc interactions between the genes. Ch 1 Ch 2 !! vermillion eye gene (v) dumpy wings gene (d) 7 m.u. speckled body gene (s) In an experiment, an undergraduate student crossed pure breeding males that have red e normal wings, and normal body with pure breeding females who have vermillion wings, and speckle body to obtain an F1. Using the Drosophila gene map, answer the follow questions: еyes, dun

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.
