Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
Chemogenomics Staubli robot retrieves assay plates from incubators. Chemogenomics, or chemical genomics, is the systematic screening of targeted chemical libraries of small molecules against individual drug target families (e.g., GPCRs, nuclear receptors, kinases, proteases, etc.) with the ultimate goal of identification of novel drugs and drug targets.

The first genome to be sequenced was that of the virus φX174 in 1977; [4] the first genome sequence of a prokaryote (Haemophilus influenzae) was published in 1995; [5] the yeast (Saccharomyces cerevisiae) genome was the first eukaryotic genome to be sequenced in 1996. [6]
It contains approximately 3.1 billion base pairs (3.1 Gb or 3.1 x 10 9 bp). [6] This represents the size of a composite genome based on data from multiple individuals but it is a good indication of the typical amount of DNA in a haploid set of chromosomes because the Y chromosome is quite small.

The term 'pangenome' was defined with its current meaning by Tettelin et al. in 2005; [2] it derives 'pan' from the Greek word παν, meaning 'whole' or 'everything', while the genome is a commonly used term to describe an organism's complete genetic material.
A genome is divided in coding and noncoding regions, and the last step of structural annotation consists in identifying these features within the genome. In fact, the primary task in genome annotation is gene prediction , which is why numerous methods have been developed for this purpose. [ 19 ]
The first type is a circular genome that has introns (type 2) and may range from 19 to 1000 kbp in length. The second genome type is a circular genome (about 20–1000 kbp) that also has a plasmid-like structure (1 kb) (type 3). The final genome type found in plants and fungi is a linear genome made up of homogeneous DNA molecules (type 5).
The paper examined the global distribution of SINEs in mouse and human chromosomes and determined that this distribution was very similar to genomic distributions of genes and CpG motifs. [12] The distribution of SINEs to genes was significantly more similar than that of other non-coding genetic elements and even differed significantly from the ...
