Bioinformatics


Bioinformatics is a fascinating field that bridges biology, computer science, and mathematics.

History:
             The term “bioinformatics” was coined in 1970 by Paulien Hogeweg and Ben Hesper. Initially, it focused on information processes in biotic systems, running parallel to biochemistry. Explosive growth occurred in the mid-1990s, driven by the Human Genome Project and advances in DNA sequencing technology .

                         Let’s delve into it:
                                                                        Definition:

"Bioinformatics is an interdisciplinary science that develops methods and software tools for understanding biological data, especially when dealing with large and complex datasets. It involves analyzing and interpreting biological information using techniques from biology, chemistry, physics, computer science, and statistics"
 
Applications:

Genomics: Bioinformatics aids in sequencing and annotating genomes, identifying genes, and understanding genetic mutations.

Proteomics: It explores the organizational principles within nucleic acid and protein sequences.

Drug Designing: By analyzing biological data, bioinformatics contributes to drug discovery and development.

Microbial Studies: It helps unravel microbial genomes and their functions.

Evolutionary Aspects: Bioinformatics sheds light on the evolutionary processes in molecular biology.

Structural Biology: It simulates and models DNA, RNA, proteins, and biomolecular interactions 134.

Tutorial Blast (NCBI)

  Object:   Starting with an organism and a protein, find a protein sequence and gene coding region.   Example:  Find the protein sequence and gene coding region for pathogenicity factor   listeriolysin O  from the bacterium  Listeria monocytogenes .     Searching for gene and protein information   Begin the search in  Gene , because it has less redundancy than Protein (this same search in Protein retrieves over 1000 records).   Search:   Listeria monocytogenes[organism] AND listeriolysin O[ protein name]   (see  Searchable fields in Gene )     One record, for gene symbol  hly , is retrieved. It is associated with an NC_ accession number (specifying a complete genomic molecule that is usually a reference assembly; see  RefSeq accession numbers and molecule types ).   To find the  gene coding sequence , look at the  Genomic regions, transcripts, and products  section or th...

Genetic Mutations

  GENETIC MUTATIONS Genetic mutations  are spontaneous changes occurring in the genetic material, (DNA) of an individual. Mutations can be passed to the next generations or may not, depending upon the type of cell in which they occur.       They can be harmful, beneficial or even neutral. Usually these are caused naturally but they can be caused by harmful radiations or chemicals or drugs etc. Somatic cell’s mutations do not pass to the offspring. While the mutations in germ line cells are hereditary. The term mutation was given by Devries in 1909. Types of Mutations Two most basic categories of mutations are: Point mutations These mutations are those occurring only at certain points in chromosomes or the genes if it. For example, insertion, deletion etc. Chromosomal mutation More sever class of mutations is chromosomal mutations. It includes deletion of one or set of chromosome, or may be more number of chromosomes is present in genome than normal numbers....
molecules Cell Cycle Phases and Checkpoints The cell cycle is a set of steps cells go through to grow, replicate, divide, and start the process again. The  cell cycle  is a series of events that cells go through to grow, replicate their  DNA , and divide. This process is vital for the growth, development, repair, and maintenance of living organisms. A consistent and regulated progression through the cell cycle ensures the proper duplication and distribution of a cell’s genetic material. Overview of the Cell Cycle Phases The two broad phases of the cell cycle are interphase and  mitosis . During interphase, cells grow, replicate their DNA and  organelles , and prepare for division. Interphase steps are the first gap phase (G 1 ), the synthesis phase (S), and the second gap phase (G 2 ). Cells divide during mitosis (M). The final step of mitosis, or the following step (depending on your source) is cytokinesis. Cytokinesis is the division of the cell’s cytoplasm, w...
