During electrophoresis, DNA molecules can easily be separated according to size because all DNA molecules have the same charge–m
ass ratio and the same shape (long rod). Would you expect RNA molecules to behave in the same manner as DNA during electrophoresis? Why or why not? Klug, William S.. Essentials of Genetics (p. 181). Pearson Education. Kindle Edition.
To separate DNA using agarose gel electrophoresis, the DNA is loaded into pre-cast wells in the gel and a current applied.
Explanation:
The phosphate backbone of the DNA (and RNA) molecule is negatively charged, therefore when placed in an electric field, DNA fragments will migrate to the positively charged anode.
Explanation:-All stem cells from a given organism contain the same genome. -All stem cells have the capacity to differentiate into specialized cell types. -Stem cells replenish our skin cells and red blood cells. i hope this helps
The Hay-flick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
any process of formation or growth; development: the evolution of a language; the evolution of the airplane. a product of such development; something evolved: The exploration of space is the evolution of decades of research
