Gene Amplification - 새창 A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.
Synonyms : Amplification, Gene
Gene Components - 새창 The parts of the gene sequence that carry out the different functions of the GENES.
Synonyms : Component, Gene, Components, Gene, Gene Component
Gene Conversion - 새창 The asymmetrical segregation of genes during replication which leads to the production of non-reciprocal recombinant strands and the apparent conversion of one allele into another. Thus, e.g., the meiotic products of an Aa individual may be AAAa or aaaA instead of AAaa, i.e., the A allele has been converted into the a allele or vice versa.
Synonyms : Conversion, Gene, Conversions, Gene, Gene Conversions, Polar Recombinations, Polarons, Recombination, Polar, Recombinations, Polar
Gene Deletion - 새창 A genetic rearrangement through loss of segments of DNA or RNA, bringing sequences which are normally separated into close proximity. This deletion may be detected using cytogenetic techniques and can also be inferred from the phenotype, indicating a deletion at one specific locus.
Synonyms : Deletion, Gene, Deletions, Gene, Gene Deletions
Gene Dosage - 새창 The number of copies of a given gene present in the cell of an organism. An increase in gene dosage (by GENE DUPLICATION for example) can result in higher levels of gene product formation. GENE DOSAGE COMPENSATION mechanisms result in adjustments to the level GENE EXPRESSION when there are changes or differences in gene dosage.
Synonyms : Copy Number, Gene, Copy Numbers, Gene, Dosage, Gene, Dosages, Gene, Gene Copy Numbers, Gene Dosages, Number, Gene Copy, Numbers, Gene Copy
