The transmission of genetic material from one generation to the next is necessary for the survival of a species. Which statement
describes one property that helps to ensure the reliable transmission of genetic information in living organisms? Question 4 options:
A)
RNA uses a nucleotide base called uracil to distinguish itself from DNA.
B)
A pyrimidine base will only pair with the correct purine base.
C)
The two strands of a DNA molecule cannot be separated.
D)
Translation of mRNA to assemble a protein is a reversible process.
The correction option is B. DNA is the genetic material in living organisms and it is the basis for inheritance. DNA molecule is made up of nitrogenous bases, deoxyribose sugars and phosphate groups. In order for the genetic information in the DNA molecules to be preserved, the components of the DNA must be arranged in the correct order without any any error. Thus, for the nitrogenous bases inside the DNA molecule, they must be correctly paired with one another.
