Gene prediction. In computational biology, gene prediction or gene finding refers to the process of identifying the regions of genomic DNA that encode genes. This includes protein-coding genes as well as RNA genes, but may also include prediction of other functional elements such as regulatory regions. Gene finding is one of the first and most ...
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. Translation is accomplished by the ribosome , which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA ...
DNA and RNA codon tables. The standard RNA codon table organized in a wheel. A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs ...
Codon degeneracy. Degeneracy or redundancy [1] of codons is the redundancy of the genetic code, exhibited as the multiplicity of three-base pair codon combinations that specify an amino acid. The degeneracy of the genetic code is what accounts for the existence of synonymous mutations. [2] : . Chp 15.
Code construction via a Binary Mapping. Perhaps a simpler approach to building/designing DNA codewords is by having a binary mapping by looking at the design problem as that of constructing the codewords as binary codes. i.e. map the DNA codeword alphabet onto the set of 2-bit length binary words as shown: , , , .
Synaptosomal-Associated Protein, 25kDa ( SNAP-25) is a Target Soluble NSF ( N -ethylmaleimide-sensitive factor) Attachment Protein Receptor ( t-SNARE) protein encoded by the SNAP25 gene found on chromosome 20p12.2 in humans.
By convention, the coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction . Wherever a gene exists on a DNA molecule, one strand is the coding strand (or sense strand ), and the other is the noncoding strand (also called the antisense strand, [3] anticoding strand, template strand or ...
Human mitochondrial genetics is the study of the genetics of human mitochondrial DNA (the DNA contained in human mitochondria ). The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to ...
