DNA sequencing and gene structure.
When we work out the structure of DNA molecules, we examine the fundamental level that underlies all process in living cells. DNA is the information store that ultimately dictates the structure of every gene product, delineates every part of the organism. The order of the bases along DNA contains the complete set of instructions that make up the genetic inheritance. We do not know how to interp...
متن کاملDNA computing based on insertions and deletions.dvi
Despite the complexity of the technology involved, the idea behind DNA computing is the simple observation that the following two processes, one biological and one mathematical, are analogous: (a) the very complex structure of a living being is the result of applying simple operations (copying, splicing, etc.) to initial information encoded in a DNA sequence, (b) the result f(w) of applying a c...
متن کاملGene Family: Structure, Organization and Evolution
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
متن کاملChromatin structure analysis enables detection of DNA insertions into the mammalian nuclear genome
Background Genetically modified organisms (GMOs) have numerous biomedical, agricultural and environmental applications. Development of accurate methods for the detection of GMOs is a prerequisite for the identification and control of authorized and unauthorized release of these engineered organisms into the environment and into the food chain. Current detection methods are unable to detect unch...
متن کاملUnidirectional gene conversion associated with two insertions in neurospora crassa mitochondrial DNA.
The mitochondrial phenotype of [poky] and other extranuclear Neurospora mutants is known to predominate over that of wild type in heteroplasmons. In the present work, we have investigated the interaction between wild-type and [poky] mtDNAs using as many as four physical markers to distinguish the two types of mtDNAs. Two insertions, one of 1200 bp in Eco RI-5 and the other 50 bp in Eco RI-9, ar...
