Shotgun sequencing. In genetics, shotgun sequencing is a method used for sequencing random DNA strands. It is named by analogy with the rapidly expanding, quasi-random shot grouping of a shotgun . The chain-termination method of DNA sequencing ("Sanger sequencing") can only be used for short DNA strands of 100 to 1000 base pairs.
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. [9] It is mainly used as a eugeroic ( wakefulness promoter) or as a mild cognitive enhancer to increase alertness and attentional performance. [10] [11] Caffeine acts by blocking binding of adenosine to the adenosine A 1 receptor, which enhances release of the ...

The general form of its probability density function is. The parameter is the mean or expectation of the distribution (and also its median and mode ), while ...
Positive and zero values have been highlighted. In bioinformatics, the BLOSUM ( BLO cks SU bstitution M atrix) matrix is a substitution matrix used for sequence alignment of proteins. BLOSUM matrices are used to score alignments between evolutionarily divergent protein sequences. They are based on local alignments.
