The aim of this study was to determine the extent of DNA fragmentation and the presence of single/denatured or double stranded of DNA in sperm with large nuclear vacuoles (LNV) selected by high-magnification. A total of ...

Many prokaryotic nucleoid proteins bend DNA and form extended helical protein-DNA fibers rather than condensed structures. On the other hand, it is known that such proteins (such as bacterial HU) strongly promote DNA ...

DNA synthesis in epimastigote forms of Trypanosoma cruzi was studied autoradiographically by incorporation of [3H]thymidine in the nuclear and kinetoplast DNA. Both DNA were heavily labelled. Three eukaryotic DNA polymerase ...

Homeostasis comprises the tendency of an organism or cell to regulate their chemical processes that take place internally so as to maintain health, vital functions and stability, owing to the coordinated response of its ...

Human DNA quantification, DNA degradation assessment and gender determination are key aspects in most field of human DNA analysis. The assay reported here is a tri-plex Real Time quantitative PCR reaction followed by high ...

Satellite DNA (satDNA) is an abundant fraction of repetitive DNA in eukaryotic genomes and plays an important role in genome organization and evolution. In general, satDNA sequences follow a concerted evolutionary pattern ...
