Write the base sequence for the mRNA that would be formed during transcription from the DNA template strand with the base sequence 5' CGGATATTG 3' . Remember, DNA and RNA strands are written from the 5' to the 3' end.
What data obtained from the chemical analysis of DNA supported the idea of complementary base pairing in DNA?
Essentially, there were two major pieces of evidence, although your teacher is probably only thinking of one piece of evidence -- percent composition of DNA.
In other words, whenever anyone analyzed the percent A,T,G, and C in DNA, they always found out that the %A = %T and they also ...
The concept of complementary base pairing in DNA is explained.
