Answer: No, mRNA ( messenger RNA) model does not closely resemble the DNA strand from which it is transcribed.
This is because mRNA strand is complementary to the strand of DNA template that is used in its synthesis during the process called transcription. The polarity of DNA template is 3' to 5' whereas that of mRNA transcribed is 5' to 3' that is both the strands have antiparallel polarity.
This is the reason template DNA is referred antisense. mRNA strand more closely resembles the sense strand ( which is complementary strand of DNA template in a double helix).
I don't think that is right !!! .....some planktons can be eaten and it is not release cO2 back in air. so false !
The smallest unit of a compound is called a molecule. Molecules are made
up of atoms that are held together by bonds which is a result by
sharing or exchange of electrons.
