In general every human ailment has some basis in our genes. recently, doctors were able to take the study of genes, or genetics, into consideration only in cases of birth defects and a limited set of other diseases. These were conditions, such as sickle cell anemia, which have very simple, predictable inheritance patterns because each is caused by a change in a single gene. Genomics is a discipline in genetics that applies recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyze the function and structure of genomes (the complete set of DNA within a single cell of an organism). The field includes efforts to determine the entire DNA sequence of organisms and fine-scale genetic mapping. The field also includes studies of intragenomic phenomena such as heterosis, epistasis, pleiotropy and other interactions between loci and alleles within the genome. In contrast, the investigation of the roles and functions of single genes is a primary focus of molecular biology or genetics and is a common topic of modern medical and biological research. Research of single genes does not fall into the definition of genomics unless the aim of this genetic, pathway, and functional information analysis is to elucidate its effect on, place in, and response to the entire genome's networks.
Impact factor of a particular journal will give complete picture of the quality and standards of the journals. For example, if a journal has an impact factor of 5 in 2011, then its papers published in 2009 and 2010 received 5 citations each on average in 2011. The 2011 impact factor of a journal would be calculated as follows:
X = Number citation for the articles published during 2009 and 2010.
Y = the total number of articles published by that journal in 2009 and 2010
2011 impact factor = X/Y.
