background: some dynamic changes occurs during spermatogenesis such as histone removal and its replacement with transition nuclear protein and protamine. these proteins are required for packing and condensation of sperm chromatin. jhdm2a is a histone demethylase that directly binds to promoter regions of tnp1 and prm1 genes and controls their expression by removing h3k9 at their promoters.objec...
Restriction fragment length polymorphisms (RFLPs) associated with interspersed simple repetitive DNA arise from DNA fragment lengths that contain variable numbers of the repeated motifs. Using restriction enzymes with different 4 base pair recognition sites and the simple triplet repeat hybridization probe, (GTG)5/(CAC)5, DNA multilocus fingerprints can be obtained in man. Only the DNAs of mono...

Variations in DNA sequence generate polymorphisms which can be followed through families. A cloned gene specific probe for human complement 3 (C3) was hybridised to DNA samples digested with restriction endonucleases. The C3 probe detects several restriction fragment length polymorphisms (RFLPs) that occur frequently in the general population. These DNA alleles can be readily used in linkage an...
