Question
Write your big picture goal for this experiment, using language that a non-biologist could understand.
(I have been struggling using non-biologist lingo because the teacher has been docking me every time i've done a prelab so I need help with phrasing please. this is the summary of the experiment:
The banding patterns on your gel reveal information about the protein composition of muscle
from your seafood samples. Proteins are synthesized according to the genes of an organism’s DNA. Since closely related organisms share similar DNA sequences, the proteins encoded by their DNA should be very similar as well, and similar protein compositions should be reflected in banding patterns. Different branches of related organisms separated at different evolutionary times. The further apart species are on the tree, the less related they are. Mollusks and arthropods diverged from one another before the emergence of chordates, animals with backbones, very early in evolutionary time. These animals are only distantly related to fish, birds, reptiles, mammals and amphibians, which are more closely related to each other. We will compare the information we can obtain from protein samples with the information we can obtain from DNA analysis of these organisms.)
Explanation / Answer
- To know the protein pattern of any organism the gel electrophoresis is done where protein banding appears by which information about protein composition in muscle can be reveal.
-Proteins are synthesized from gene of DNA.
-As closely related organism share some extent of similar DNA sequences,so the protein encoded by them also show similarity,so the pattern shown by these protein shows similar banding pattern.
-speceise having different branches of related organism separated during different evolutionary process.
-The further apart species lives on tree and hence related they are.
-Very early during evolution mollusks and arthropods diverged from one another very before the emergence of chordates animals with backbones.
-So,they are only distantly related to fish,birds,reptiles, mammals and amphibians(but these animals are closely related to each other
-And this result is known by obtaining sample from the DNA of these organism.
