What is the definition of pedigree in biology?Pedigree AnalysisPedigrees have been used in the field of genetics for much longer than the technology to sequence DNA has been around. Pedigrees are used to establish patterns of inheritance for certain traits....
In the early part of the twentieth century, scientists knew whatgenesdid, but they did not know what they were. Francis Crick, one of the codiscoverers of the three-dimensional double helical structure ofDNA, was among the first to propose that a gene was alinearsequence of nucleotides and...
By definition, a relict is something that remains from an entity that has mostly disappeared (Merriam-Webster 2014; Lincoln et al. 1982). In evolutionary biology, a relict species remains of a group that is mainly extinct (Grandcolas et al. 2014; Fig. 1). The basis for this inference is...
Based on the work of these scientists, genetic engineering wasdeveloped in 1973. This method is the foundation of modern biotechnology practices and recent advances. It enabled the first direct manipulation of plant and animal genomes, which is the complete set of genes present in a cell. ...
Definition What is genomics? Genomics is the study of an organism's entire genome, including all its genes and how those genes interact with each other and their environment. The genome contains the organism's complete set of DNA and is embedded in nearly every cell of that organism....
