Bioinformatics uses biology, chemistry, physics, computer science, data science, computer programming, information engineering, mathematics and statistics to analyze and interpret biological data. The process of analyzing and interpreting data can sometimes be referred to as computational biology , however this distinction between the two terms ...
Memory transfer proposes a chemical basis for memory termed memory RNA which can be passed down through flesh instead of an intact nervous system. Since RNA encodes information [ 1 ] and living cells produce and modify RNA in reaction to external events, it might also be used in neurons to record stimuli.
Four fields in the microinstruction contribute to the new address. CA, 4 bits: Part of the next address, depending on the other fields. CB, 4 bits: Determines bit 1 of the next address. CC, 4 bits: Determines bit 0 of the next address. CD, 2 bits: Controls how the next address is assembled (except when the CB field contains 15).
DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.
Historically, sequencing was done in sequencing centers, centralized facilities (ranging from large independent institutions such as Joint Genome Institute which sequence dozens of terabases a year, to local molecular biology core facilities) which contain research laboratories with the costly instrumentation and technical support necessary. As ...
In a sequence of biochemical events, feedback would refer to a downstream element in the sequence (B in the adjacent image) affecting some upstream component (A in the adjacent image) to affect its own production or activation (output) in the future. If this element acts to enhance its own output, then it engages in positive feedback (blue ...
Cellular memory modules were discovered by François Jacob and Jaques Monod in 1961 at the Pasteur Institute in Paris. The discovery led to Jacob and Monod, along with André Lwoff, receiving The Nobel Prize in Physiology or Medicine in 1965 for their discoveries regarding genetic control of enzyme and virus synthesis. These experimental ...
In bioinformatics, sequence assembly refers to aligning and merging fragments from a longer DNA sequence in order to reconstruct the original sequence. [1] This is needed as DNA sequencing technology might not be able to 'read' whole genomes in one go, but rather reads small pieces of between 20 and 30,000 bases, depending on the technology used. [1]
