• Gene
  • Plasmid DNA vaccines are genetically engineered to contain a gene which encodes for an antigen or a protein produced by a pathogenic virus, bacterium or other parasite. (wikipedia.org)
  • The terms chromosome and gene were used long before biologists really understood what these structures were. (encyclopedia.com)
  • The Watson and Crick discovery made it possible to express biological concepts (such as the gene) and structures (such as the chromosome) in concrete chemical terms. (encyclopedia.com)
  • The gene then needs to be mapped by comparing the inheritance of the phenotype with other known genetic markers. (wikipedia.org)
  • allele one of multiple alternative forms of a single gene, each of which is a viable DNA sequence occupying a given position, or locus on a chromosome. (wikipedia.org)

  • Mendelian
  • In classical genetics, Mendelian laws specify that the inheritance of traits passed from one generation to the next can only occur through sexual reproduction as information is passed down through the chromosomes of a species' germline cells (egg and sperm), and never through somatic (bodily) cells. (sott.net)
  • In cases in which this has been thoroughly investigated, the sperm-delivered sequences have been seen to remain extrachromosomal and to be sexually transmitted to the next generation in a non-Mendelian fashion . (sott.net)
  • Chromatin
  • Some use the term chromosome in a wider sense, to refer to the individualized portions of chromatin in cells, either visible or not under light microscopy. (wikipedia.org)
  • repeats
  • The linear plasmids which contain a protein that has been covalently attached to the 5' end of the DNA strands are known as invertrons and can range in size from 9 kb to over 600 kb consisting of inverted terminal repeats. (wikipedia.org)
  • Although his hypothesis turned out to be wrong, Mojica surmised at the time that the clustered repeats had a role in correctly segregating replicated DNA into daughter cells during cell division because plasmids and chromosomes with identical repeat arrays could not coexist in Haloferax volcanii. (wikipedia.org)
  • copies per cell
  • The total number of a particular plasmid within a cell is referred to as the copy number and can range from as few as two copies per cell to as many as several hundred copies per cell. (wikipedia.org)
  • anaphase
  • In animal cells, chromosomes reach their highest compaction level in anaphase during segregation. (wikipedia.org)
  • anaphase aneuploidy anticodon autosome Contents: Top 0-9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z bacterial artificial chromosome (BAC) base pair A pair of nucleotide bases on complementary DNA or RNA strands organized in a double helix. (wikipedia.org)
  • Boveri
  • Aided by the rediscovery at the start of the 1900s of Gregor Mendel's earlier work, Boveri was able to point out the connection between the rules of inheritance and the behaviour of the chromosomes. (wikipedia.org)
  • phenotype
  • The 'old faithful,' the rol-6D plasmid pRF4 confers a dominant roller phenotype, advantageous because for most applications no further genetic manipulations need be made to a starting strain. (ucr.edu)
  • variations
  • The modes of genetic information delivery in this process are closely reminiscent of those operating in RNA-mediated paramutation inheritance, whereby RNA is the determinant of inheritable epigenetic variations , . (sott.net)
  • arrays
  • Although the vast majority of researchers use rol-6D (plasmid pRF4) to mark transgenic arrays, there may be advantages to using other genes, as described below. (ucr.edu)
  • found
  • The least number of chromosomes are found in Ascaris megalocephala i.e., 2 (\[n=2\]in Mucor hiemalis in plants ) while in a radiolarian protist ( Aulocantha ) has maximum number of chromosomes is 1600 ( Ophioglossum reticulatum , 2 n = 1262 in plants). (studyadda.com)
  • resistance
  • Mercury Resistance Transposon Tn813 Mediates Chromosome Transfer in Rhodopseudomonas sphaeroides and Intergeneric Transfer of pBR322. (moluna.de)
