Identifying the network (regulatory) of genes. Learning evolutionary relationships by constructing phylogenetic trees. Classifying and predicting protein ...
A second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965). Watson's version differs from Crick's because Watson describes a two-step (DNA → RNA and RNA → protein) process as the central ...
Differential display (also referred to as DDRT-PCR or DD-PCR) is a laboratory technique that allows a researcher to compare and identify changes in gene expression at the mRNA level between two or more eukaryotic cell samples. [1] It was the most commonly used method to compare expression profiles of two eukaryotic cell samples in the 1990s. [1]
Three-dimensional structure of a protein. Structural bioinformatics is the branch of bioinformatics that is related to the analysis and prediction of the three-dimensional structure of biological macromolecules such as proteins, RNA, and DNA. It deals with generalizations about macromolecular 3D structures such as comparisons of overall folds ...
In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [1] Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix.
Watson and Alexander Rich discussed in the PNAS, saying, "We shall not be able to check a structural relationship between RNA and protein synthesis or between RNA and DNA until we know the structure of RNA." [5] Evidences had been accumulating since the 1940s that protein synthesis occurs simultaneously with increased level of RNA in the cytoplasm.
Pairwise Comparison: The Pairwise comparison of genomic sequence data is widely utilized in comparative gene prediction. Many studies in comparative functional genomics lean on pairwise comparisons, wherein traits of each gene are compared with traits of other genes across species. his method yields many more comparisons than unique ...
Biological data is highly complex when compared with other forms of data. There are many forms of biological data, including text, sequence data, protein structure, genomic data and amino acids, and links among others. RNA polymerase (purple) is a complex enzyme at the heart of transcription.
