N6-methyladenine: The other methylated base of DNA

Article Abstract:

Biological importance of N6-methyladenine (m6A) as the sixth methylated base of DNA is reviewed, providing useful information about the development of new ideas and hypotheses about the possible functions of m6A in eukaryotic cells. Presence of m6A in mammal DNA suggested by indirect evidences raise the possibility that it might have remained undetected due to low sensitivity of analytical methods.

The size and form of chromosomes are constant in the nucleus, but highly variable in bacteria, mitochondria and chloroplasts

Article Abstract:

The size and the form of chromosomes in various organisms by various cytological examinations are investigated. The analysis reveals that the chromosomes are highly variable in several organisms like bacteria, mitochondria and chloroplasts, while are always constant in the nucleus under normal circumstances.

A unifying new model of cytokinesis for the dividing plant and animal cells

Article Abstract:

A unifying model is developed that describes a conserved mode of plant and animal cytokinesis. The discovered similarities between the plant and animal cell division suggest a modification of the general views on the disparity between plant and animal cytokinesis.
