Answer #1

A gene family indicates a set of many similar genes which are formed by duplication of a single original gene and generally having similar biochemical functions.

Example of such gene family is the genes for human hemoglobin subunit. There are ten genes in this family. The ten genes are present in two clusters on different chromosome. These two loci on the chromosome are the α-globin and β-globin loci. The position of the genes of this gene family are as follows:

HBA1 - 16p13.3

HBA2 - 16p13.3

HBB - 11p15.4

HBD - 11p15.4

HBE - 111p15.4

HBG1 - 111p15.4

HBG2 - 11p15.4

HBM - 16p13.3

HBQ1 - 16p13.3

HBZ - 16p13.3

Protein functions: These genes are responsible for the production of globin protein which is essential for the formation of hemoglobin as a part of RBC. These hempglobin in RBC binds with oxygen and carry the oxygen atom to whole body and thus perform respiration process.

Eukaryotic genes can be introduced into bacteria by recombinant DNA techniques. If the introduced gene encodes a protein that is also found in bacteria - for example, a universally used glycolysis enzyme - then, expression of the eukaryotic gene may produce a protein that functions in the bacterial cell. The mouse gene for a glycolysis enzyme is introduced into an E. coli cell that has a mutant gene for the bacterial version of the same enzyme. Even though the mouse...

Case Scenario LSS is engaged in flood relief support nationally and has been asked to do several international Camp Noah projects. Last year the French government asked for resources for children in Southeastern France who had been affected by floods; LSS responded within 15 weeks with a French Camp Noah curriculum that met many of the project objectives. The Board of Directors of LSS commended the effort; international expansion was added to this year’s strategic objectives for the LSS organization....
