Indicate which of the following statements is FALSE.a. Covalent bonds connect nucleotides in a strand; noncovalent interactions
hold strands into a double-stranded structure.b. Uracil is similar to thymine except that uracil lacks a methyl group on the carbon at position 5 on the carbon-nitrogen ring.c. Frederick Griffith demonstrated that a transforming chemical from dead bacteria could change the genetic information of living bacteria.d. Avery, MacLeod, and McCarty showed that DNA is the genetic information of cells and that RNA is the genetic information of viruses.e. The pyrimidine bases in nucleic acids are cytosine, thymine, and uracil.
The false statement is d Avery,Macleod and McCarty showed that DNA is the genetic information of cells and RNA is the genetic information in the viruses .
Explanation:
Avery,Macleod and MacCarty showed that DNA is the genetic material of the cell.
On the other hand Fraenkel, Conrat and Sanger carried out their experiment on tobacco mosaic virus to prove that RNA act as genetic material in some viruses.
