Major General Jahangir Alam Chowdhury, the Director General of the Bangladesh Rifles (BDR), in a talk with the Director General of the Border Security Force (BSF) Ajay Raj Sharma in 2004 said that the extremist group Banga Sena was carrying out terrorist and secessionist activities against Bangladesh from its bases in the Indian state of West Bengal.

TILLING (Targeting Induced Local Lesions in Genomes) is a method in molecular biology that allows directed identification of mutations in a specific gene.TILLING was introduced in 2000, using the model plant Arabidopsis thaliana, and expanded on into other uses and methodologies by a small group of scientists including Luca Comai.
dbSNP is an online resource implemented to aid biology researchers. Its goal is to act as a single database that contains all identified genetic variation, which can be used to investigate a wide variety of genetically based natural phenomena.
The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.The biomolecular data used for such calculations are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins.
An indel inserts or deletes nucleotides from a sequence, while a point mutation is a form of substitution that replaces one of the nucleotides without changing the overall number in the DNA. Indels can also be contrasted with Tandem Base Mutations (TBM), which may result from fundamentally different mechanisms. [ 4 ]
RFLP analysis is now largely obsolete due to the emergence of inexpensive DNA sequencing technologies, but it was the first DNA profiling technique inexpensive enough to see widespread application. RFLP analysis was an important early tool in genome mapping , localization of genes for genetic disorders , determination of risk for disease, and ...
For example, a specific type of mutation in one specific area of mtDNA was found to be in several different tumor types. [ 9 ] Mitochondria often undergo fission and fusion , which means that different organelles in the same cell can fuse together to become one mitochondria, or can break apart and become two. [ 10 ]
