objective(s):from the ancient era, emergence of agriculture in the connecting region of mesopotamia and the iranian plateau at the foothills of the zagros mountains, made iranian gene pool as an important source of populating the region. it has differentiated the population spread and different language groups. in order to trace the maternal genetic affinity between iranians and other populatio...

abstract: a pure nucleotide pool is an essential precursor of correct dna replication and prevention of mutagenesis and abnormality in a living cell. inosine triphosphatase (itpase) is a critical enzyme to remove any deaminated rough purine nucleotides such as inosine from nucleotide pool. it has been shown that the rate of substitution mutation in genomic dna increase by abnormal function and ...

Any good journalist knows that, if you can’t deliver the facts, at least you can offer up a bit of entertainment. Genome scientists have co-opted that strategy when it comes to the seemingly immortal question of how many human genes there are. Frankly, nobody seems to have a clue. So at the Cold Spring Harbor Laboratory genome meeting this May, they decided to collect a different form of data —...

objective: one of the most significant damages to the genetic material is oxidative deamination of dna and free nucleotides in the cell pool. incorporation of deaminated purine nucleotides such as inosine triphosphate (itp, ditp) into the dna can increase the frequency of base substitution mutation. it has been suggested that presence and accumulation of these rough nucleotides can lead to gene...
