...  Our results provide strong evidence that Arabidopsis XRCC2, RAD51B and RAD51D have complex functions in somatic DNA repair and gene regulation, arguing for further studies of these ancient genes that have been maintained in both plants and animals during their long evolutionary history. ...

The male was chosen to be double homozygous recessive on purpose so that crossing over does not matter because the same gametes form either way. Thus, from this experiment one can determine the frequency of crossing over in a SINGLE INDIVI ...

In diploid (2n) organisms, the genome is composed of one set of each homologous chromosome pair, as c ...

Weetman (1937) proposed that three alleles at a single locus determined rind pattern. The allelic series was renamed to G, gs, and g by Poole (1944), since g was used to name the rec ...

These sexgene interactions imply an underlying genetic network invoked by sex-specific regulation influencing gene expression (13). Indeed, sex differences in the expression of thousand ...

... Gene clustering also becomes the first step to uncover the regulatory elements in transcriptional regulatory networks [Alon1999, Tavazoie1999, Xing2001].

... A gene is a recipe for a protein. It is used by the cell to make that protein. In achondroplasia, the normal allele (FGRF3) codes for a protein (fibroblast growth factor) that is part of the structure of normal bones, including those of the arms and legs. The achondroplasia allele produces a protein ...

Ridge (biology)

Ridges (regions of increased gene expression) are domains of the genome with a high gene expression; the opposite of ridges are antiridges. The term was first used by Caron et al. in 2001. Characteristics of ridges are:Gene denseContain many C and G nucleobasesGenes have short intronshigh SINE repeat densitylow LINE repeat density↑ 1.0 1.1
