Analysis of chromosome iii replicators reveals an unusual structure for the ars318 silencer origin and a conserved wtw sequence within the origin recognition complex binding site
Saccharomyces cerevisiae chromosome III encodes 11 autonomously replicating sequence (ARS) elements that function as chromosomal replicators. The essential 11-bp ARS consensus sequence (ACS) that binds the origin recognition complex (ORC) has been experimentally defined for most of these replicators but not for ARS318 (HMR-I), which is one of the HMR silencers. In this study, we performed a ...

Chromosomal aberration analysis in lymphocytes from workers exposed to I-131 in nuclear medicine departments in Iran
In order to evaluate the cytogenetic effects of low doses of radiation by internal or external exposure to iodine-131, we analysed chromosomal aberrations (CA) in peripheral blood lymphocytes from 34 subjects working in the nuclear medicine departments in Iran. The studied groups consisted of 26 individuals (Group A) who were employed in these centres without any evidence of radiation exposure by ...

Karyotype Analysis for Rare Disease
Karyotype analysis refers to the pairing and grouping of chromosomes to reveal whether the organism accords with the inherent chromosomal characteristics, to determine if the organism has chromosomal abnormalities. Karyotype analysis can detect whether there are abnormalities in chromatin length, centromere position, the ratio of long and short arms, and the presence or absence of satellites. ...

What is Restriction Endonuclease?
Restriction endonuclease, also known as restriction enzyme, is a class of enzymes isolated from bacteria by W. Arber, H. Smith and D. Nathans et al. (1979). Restriction enzymes have extremely high specificity. They recognize specific sites on double-stranded DNA and cut both strands to form sticky or blunt ends. Restriction enzymes can be used to dissect delicate DNA molecules, and are ...

Chromosomal aberrations in radiation workers of radiology departments in Northern Iran-Babol
We determined the frequency of chromosomal aberrations using the metaphase analysis method in radiation workers of radiology departments in Babol. Blood samples were prepared from 62 radiology workers and 29 individuals as controls, and lymphocytes were cultured in a culture medium. Results showed that the mean frequencies of the total chromosomal aberration in radiation workers are significantly ...
