Guida verificata passo dopo passo1
Understand that a DNA nucleotide is the basic building block of DNA, consisting of three components.
Identify the sugar component in a DNA nucleotide. DNA contains deoxyribose sugar, not glucose or ribose.
Recognize the phosphate group as a key component that links nucleotides together in the DNA strand.
Determine the third component, which is a nitrogenous base. This can be adenine, thymine, cytosine, or guanine in DNA.
Eliminate incorrect options by ensuring the components match: a phosphate group, a deoxyribose sugar, and a nitrogenous base.
