In group translocation, chemical modification of molecule to be transport is done into the cell. Group translocation is type of active transport because metabolic energy is used during uptake of the molecule,. In bacteria the best known group translocation system is phosoenolpyruate: sugar phosphotransferase system (PTS) PEP + SUGAR --------- PYRUATE + sugar-phosphate In E.coli the PTS consists of two enzyme and a low molecular weight heat-stable protein(HPr)
Deletions and duplications of single-base pairs typically arise during homologous recombination and cause diseases. But what happens when a mutation occurs over multiple genes? Rearrangements of chromosomes include deletions of DNA sequences and duplications of segments, both of which can encompass thousands to hundreds of thousands of bases. Why do these large rearrangements occur? For one, certain structural features of the genome, also referred to as genome architecture, can render various regions fragile and thus prone to events such as chromosome breakage, which often result in translocations, deletions, and duplications. Often, these alterations happen due to errors during cell division when chromosomes align (Figure 1). Homologous recombination between areas of concentrated repeated sequences frequently creates deletions and duplications. Because they commonly involve more than one gene, the disorders caused by these large deletion and duplication mutations are often severe.

The four types of alterations of chromosome structure are deletion, duplication, inversion, and reciprocal translocation. Deletion is the loss of one or more nucleotides from a gene by mutation; the loss of a fragment of a chromosome. Duplication is repition of a part of a chromosome resulting from fusion with a fragment froma homologous chromosome. Duplication can result from an error in meiosis or from mutagenesis. Inversion is a change in a chromosomeresulting from reattachment of a chromosome fragment to the original chromosome, but in a reverse direction. Mutagens and errors during mesosis can cause inversions. Translocation is the attachment of a chromosomal fragment to a nonhomologous chromosome.
mitosis occurs more frequently then meiosis

In the United States, gastrostomies are more frequently performed on older persons. The procedure occurs most often in African-American populations

A few of the more common CD duplication and replication companies on the internet in the UK include PureMusic, VDC Group, and Duplication Centre. You could also check the Yellow Pages or duplication type magazines.
Mitosis occur more frequently in our body. Basically mitosis occur when we get an injury or is an asexual type of reproduction. It occurs at the time of cell division and our cells need to divide often. While meosis is form of sexual reproduction and it does not occur quite often . Also, meiosis occurs more in men than in women. Look at it this way Mitosis splits once as meosis splits twice and they're not identical
It means, within the laws of statistical analysis, that the statistic occurs more frequently than the baseline number which is considered "random" for the particular application. It happens more frequently than "random" - hence there is, or may be, something "significant" about that.
