Scientists have uncovered genetic variation in the unexplored DNA of the photosynthetic and energy factories of Arabidopsis ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

B chromosomes manipulate cell division for survival, and new research identifies key genes, including DCR28, involved in this ...

Compartment in cell where DNA is stored as chromosomes Controls activities of cell Animal cell, plant cell or fungal cell Cell structure Cell wall Description Freely permeable layer surrounding ...

Some chromosomes, such as B chromosomes, can increase their inheritance rate to their own advantage. These extra chromosomes ...

The stages outlined in the following example show a cell with a diploid chromosome number of four (two sets of two chromosomes) undergoing cell division. The replicated chromosomes are not visible ...

A human cell contains 46 chromosomes. To simplify our illustration, we'll show only four. Though the genetic code of a human being is contained within 46 chromosomes, only half of this number ...
