According to Chargaff's rule of nitrogenous base pairing, which of the following statements is correct?
If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in a DNA molecule.
If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in an RNA molecule.
If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine equals the sum of all thymine in a DNA molecule.
If all adenine bonds to uracil and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all uracil in an RNA molecule.
A compact disc (CD) stores about 4.8 × 109 bits of information in a 96 cm2 area. This information is stored as a binary code—that is, every bit is either a 0 or a 1.
how many bits would it take to specify each nucleotide pair in a DNA sequence?
how many CDs would it take to store the information contained in the human genome?
How many adenine bases are there if there are eight thousand cytosine bases in a fifteen thousand bp DNA?
