The organization of nucleotides into DNA triplets; how these relate to but differ from the codons of mRNA; the number of codons; and stop codon and their function. Introduction: The entire genetic code of an organism is encoded on the DNA. But DNA is made of nucleotide bases of only four types, adenine (A), thymine (T), guanine (G), and cytosine (C). So the entire genetic code is written as a combination of these 4 nucleotide base pairs. This genetic code controls the entire functioning of the body through formation of proteins. There are millions of proteins in the body that run an organism. But all of them are made of 20 basic amino acids. The genetic code on a DNA codes for these 20 amino acids. The 4 nucleotide bases code for these 20 amino acids by arranging in different combinations of 3. That produces 64 possible combinations. This combination of 3 nucleotide bases is called the DNA triplet. DNA triplets code for the formation of mRNA strands that serve as the mirror image of the DNA triplets. This process is called transcription. The triplet nucleotide code transcribed on the mRNA is called a codon.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
