You have isolated a true-breeding fish strain that has blue scales. Then you isolate another true- breeding fish strain that that has orange scales. You know that each of the colors are caused by recessive alleles in 2 different genes. You cross a blue fish to an orange fish and find out that all of the offspring have orange looking scales. You cross the Fi progeny with each other and find 37 fish blue scales, 27 fish have green scales, and 98 fish have orange scales. a. You suspect that the inheritance pattern is due to recessive epistasis. Draw the order of the phenotypes controlled by this biochemical pathway that would be consistent with your hypothesis.
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.
