WHAT IS GENOMICS? How is Genomics different from Genetics? Genetics looks at single genes, one at a time, like a picture or snapshot. Genomics looks at the big picture and examines all the genes as an entire system .

HISTORY OF GENOMICS Genomics can be said to have appeared in the 1980s, and took off in the 1990s with the initiation of genome projects for several biological species. The most important tools here are microarrays and bioinformatics .

HISTORY OF GENOMICS cont… Without a doubt, the introduction of the computers into molecular biology laboratories was one of the key factors in the development of the genomics. Laboratory automation led to the production of large amounts of data, and the need of analysis ,combine and understand these resulted in development of “Bioinformatics”

RELATED DEVELOPMENTS Bioinformatics and computational biology involves the use of techniques including applied mathematics, informatics, statistics, computer science, artificial intelligence, chemistry and biochemistry, to solve biological problems usually on the molecular level.

WHAT IS A GENOME? The genome broadly refers to the total amount of DNA of a single cell (haploid cell in the case of a diploid organism) of an organism, including its genes. “The whole hereditary information of an organism that is encoded in the DNA”

WHAT IS A GENOME? Genes provide the information for making all proteins that are necessary for the expression of characters. Gene Protein Character Characters refers to how an organism looks, its physiology, its ability to fight infections and even its behavior.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
