The mRNA molecule contains 440 guanyl nucleotides, 235 adenyl nucleotides, 128 cytidyl nucleotides, and 348 uridyl nucleotides. Determine: 1) how many and what nucleotides are contained in the DNA molecule, the “cast” of which is the given mRNA? 2) How long is the given section of the mRNA molecule?
According to the principle of complementarity, during transcription, RNA is also formed according to the DNA template, therefore, according to Chargaff’s rule, we will find the number of corresponding nucleotides on DNA.
1) 128 guanyl nucleotides, 348 adenyl, 440 cytidyl and 235 thymine nucleotides.
2) 128 + 348 + 440 + 235 = 1151 nucleotides
