This is very important. It's for my biology lab.How can a chromatogram be used to determne the evolutionary relationships between plants,algae,and bacteria?
Algae and higher plants are called eukaryotic. They tend to have two different types of genetic material, one located in the nucleus and a different type located in the cell鈥檚 mitochondrion. Bacteria, on the other hand, are called prokaryotic. They only contain one type of genetic material. Some bacteria鈥檚 genetic material resembles that found in the nucleus of eukaryotic cells. Some bacteria DNA or RNA more closely resembles that of mitochondrion.
Proper cleavage of the genetic material, followed by TLC or possibly paper chromatography, could show the similarities or differences. This could be used to infer (not prove) any evolutionary relationships.How can a chromatogram be used to determne the evolutionary relationships between plants,algae,and bacteria?
Hey the following are just my thoughts-
Chromatogram is used to separate chemically different compounds
If similar compounds are found in a solution made my crushing parts of plants etc, then thy are considered to be linked w/ each other somewhere.
eg., If xanthophyll is found thru chromatography in two diff plants , then thy are said to be linked somewhere as they use the exact same chemical as their photosynthetic pigment
Hope this helps you :-))
