Biological processes are made up of many chemical reactions or other events that are involved in the persistence and transformation of life forms. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.

Course Overview (in Hindi)

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance.

Replication: Quick Revision (Part-2) (in Hindi)

Genetic recombination is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.

Recombination: Quick Revision (in Hindi)

biology, a mutation is the alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA.

Mutations result from errors during DNA replication(especially during meiosis) or other types of damage to DNA (such as may be caused by exposure to radiation or carcinogens), which then may undergo error-prone repair (especially microhomology-mediated end joining.

Mutation: Quick Revision (in Hindi)

DNA repair is strictly defined as the cellular responses that are associated with the restoration of the normal base-pair sequence and structure of damaged DNA.

DNA Repair:Quick Revision (in Hindi)

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

Transcription : Quick Revision (Part-1) (in Hindi)

Transcription: Quick Revision (Part-2) (in Hindi)

All classes of RNA transcripts must be processed into mature species. The reactions include several types: Nucleolytic cleavage, as in the separation of the mature rRNA species from the primary transcript of RNA polymerase I action; Chain extension (non‐template‐directed), as in the synthesis or regeneration of the common CCA sequence at the 3′ end of transfer RNAs or of PolyA at the 3′ end of mRNAs; and Nucleotide modification, for example, the synthesis of methylated nucleotides in tRNA or rRNA. These reactions are a feature of both prokaryotic and eukaryotic gene expression, and the biological consequences are diverse. For example, modified nucleotides can affect the way in which a tRNA recognizes different codons.

The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria.

Prokaryotic Gene Regulation: Lac operan (in Hindi)

The trp operon is an operon—a group of genes that is used, or transcribed, together—that codes for the components for production of tryptophan. The trp operon is present in many bacteria, but was first characterized in Escherichia coli.

Prokaryotic Gene Regulation: Trp Operon (in Hindi)

The mechanism of action of both siRNAs and mIRNAs is mediated by Dicer and RISC complex. Dicer will cleave either pre-miRNAs or dsRNA to generate the final active molecules. As already pointed out when the complementarity between the acting RNA and the target is complete, we have a mRNA degradation (siRNA) induced by Ago2 that harbors endonuclease activity. In the case of miRNAs the complementarity is only partial with the target and we got translational repression mediated by RISC. Interestingly in plants miRNA are different from a animals, showing almost perfect matching with their targets and in this case they act as siRNAs.

Eukaryotic Gene Regulation (in Hindi)

Translation is a universal process occurs in both prokaryotes and eukaryotes. The fundamental process of translation is same inprokaryotes and eukaryotes. Members of both groups uses information present in mRNA, which is came from the DNA by transcription, to synthesize proteins with ribosome as the machinery.

Translation: Quick Revision (Part-1) (in Hindi)

Translation: Quick Revision (Part-2) (in Hindi)

Puromycin is an aminonucleoside antibiotic derived from Streptomyces alboniger which causes premature chain termination during translation in the ribosome.
