1 day ago · Cell theory states that cells are the fundamental units of life, that all living things are composed of one or more cells, and that all cells arise from preexisting cells through cell division. [40] Most cells are very small, with diameters ranging from 1 to 100 micrometers and are therefore only visible under a light or electron microscope . [ 41 ]
1 day ago · The term 'molecular biology' was first used in 1945 by the English physicist William Astbury, who described it as an approach focused on discerning the underpinnings of biological phenomena—i.e. uncovering the physical and chemical structures and properties of biological molecules, as well as their interactions with other molecules and how these interactions explain observations of so-called classical biology, which instead studies biological processes at larger scales and higher levels of ...
1 day ago · A segment of DNA that codes for the cell’ssynthesis of a specific proteinis called a gene. DNA replicatesby separating into two single strands, each of which serves as a templatefor a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix.

3 days ago · Absorbance values that are lower than the control cells indicate a reduction in the rate of cell proliferation. Conversely a higher absorbance rate indicates an increase in cell proliferation . Rarely, an increase in proliferation may be offset by cell death; evidence of cell death may be inferred from morphological change.
