Gene Expression/ Micro RNA/ PAN Genome/ Alternative Splicing/ Chip-on-Chip

@

A) Gene Expression:

Gene Expression is the Activity by which the Commands in Our DNA are Transforms into a Functional Product, Like Protein.

The Human Genome Contains Entire Genetic Information of the Organism As DNA Sequences Save in 23 Chromosomes, Design That Are Arranged From DNA & Proteins. DNA Molecule has Composed 2 Edges That From The Ionic Double-Helix "Twisted Ladder", Whose Backbone, Which is Created by Sucrose & Phosphate Molecules, is Attached by Horizontal of Nitrogen-Consisting Bases.

DNA is Made of Four Various Bases: 1) Adenine 2) Thymine 3) Cytosine 4) Guanine.

The Bases Are Everytime Paired Such as Adenine Joins Thymine & Cytosine Joins Guanine.

The Representation of DNA Sequence on a Computer, We Require to be able to Denote all Four Bases Pair Probabilities in Binary Format i.e. 0 & 1. Four DNA Base pairs Illustrate One Byte or 8 bits.

A Gene is a Strain Of DNA Which Encodes Data or Information. Genomic DNA Contains Two Reverse Complementary & Antiparallel Strands, Every One Having ‘5’ & ‘3’ ends.

B) Micro RNA:

A Micro RNA is Tiny Non-Coding RNA Unit Occurs in Animals, Plants & in Some Viruses, it Contain 22 Nucleotides. A cancellous RNA chip That Blocks the Making of Specific Protein by Building and Destructing the Traveler RNA That Would Have Created Protein. Commonly Micro-RNA is Used For Gene Silencing.

MicroRNA, First Found in Caenorhabditis Elegans, is Discovered in Most Eukaryotes, Accept Humans.

miRNA Have Important Function in Regularization of Various Actions in Mammals. They Serve a Key & Strong Tool in Gene Regulation & Thus a Prospective Novel Class of Therapeutic Aim. Micro-RNA Perform Radically Preserved Improvement Role & Different Physiological Role in Animal. MiRNAs Mostly Possess Restricted complementarity With Ther Aim mRNAs in Animals, But Yet Adequate to Adjust Various Physiological Actions. It Has Been Recommended That They Reduce The Primary Step of the Transformation Process, Which May Followed by Micro RNA Degeneration.

C) PAN Genome:

A PAN Genome or Supra-Genome Explains the Entire Complement of Gene's ina Clade, Which Can Have Huge Changes in Gene Content Among Nearly Related Ecotypes & Strains.

OpenPan Genome:

Number of Genes of Pngenome Grow with the Number of Plus Sequenced Strains.

Usually, Class That Live in More Than One environment of Hybrid Microbial Family Have Multiple Routes to Interchanging Genetic Material, and Hence Constantly Increase Their Total Group of Genes.

Example: Escherichia Coli.

Closed Pangenome:

After Given Sequenced Strains, Plus Strains Don’t Serve New Genes to The Categories Pangenome.

A cease Pangenome is Usually for Class That Lives in Rare With Limited liberty to The Universal Microbial Gene Pool. For Those Class, a Little Number of Sequenced Strains Already Cover The Full Pangenome.

Example: Bacillus anthracis

Advantages if Pan Genome:

1. It Represents Strains by Their Separate Gene Group.
2. Invent vaccines Verses Pathogenic Strains.
3. Find, Searching, Identification & tacking of New Strains in Metagenomics Samples.

D) Alternative Splicing:

Differential Splicing or Alternative Splicing is a Keep Action During Gene Expression That OutComes in One Gene Coding For More Than One Proteins. In This Action, Specific Exons of a Gene May be Contained Within or Closed Out From the Final, Actions Messenger RNA (mRNA ) Created From Thet Genes.

Functions of Alternative Splicing:

1. The Most Important Function of Alternative Splicing is to Improve the Diversity of mRNAs Definite From the Genome.
2. Alternative Splicing Modify Proteins Encoded by mRNAs, Which Has Deep Functional appearances.
3. observational deconstruction of These Proteins Isoforms Showed That Choice Splicing Regulates Building Between Proteins & NucleicAcid as Well as Between Proteins & Membranes.

E) Chip-on-Chip:

Chip-on-chip is Application That Unites Chromatin immunoprecipitation with Microarray. Chip-on-chip is Used to Examine Relation Between Protein & DNA Vivo. Usually, It Permits The Searching of The Cistrome, The Sum of Building Sites, For DNA-Building Proteins on a Genome-Wide Basis. Complete Genome Analysis Can be accomplished to Know the Place of Building Sites for Almost Any Protein of Interest.

F) DNA methylation:

DNA Methylation is Action by Which Methyl Sets Are Added to DNA Molecule. Methylation Can Modify the Action of DNA Section Without Modify Sequence.

There Is Number of Routes That Gene Expression is Controlled in Eukaryotes, But Methylation of DNA is a Regular Epigenetic Signaling Tool That Cells Usage to Seal Genes in The "Off" Place.
