Which of the following is a nucleotide found in DNA?
a
deoxyribose + phosphate group + uracil
b
ribose + phosphate group + uracil
c
deoxyribose + phosphate group + cytosine
d
ribose + phosphate group + thymine
d) deoxyribose + phosphate group + thymine
Thats not a choice
Apologies for the confusion. The correct answer is:
c) deoxyribose + phosphate group + cytosine
The correct answer is option C - deoxyribose + phosphate group + cytosine.
To determine the correct nucleotide found in DNA, we need to consider the components that make up the structure of DNA. DNA, or deoxyribonucleic acid, consists of repeating units called nucleotides.
A nucleotide is composed of three main parts:
1. A sugar molecule called deoxyribose.
2. A phosphate group, which consists of a phosphorus atom bound to four oxygen atoms.
3. One of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T).
In this case, option C includes deoxyribose, a phosphate group, and the nitrogenous base cytosine. The other options do not contain the correct components to form a nucleotide found in DNA.
Therefore, the correct nucleotide found in DNA is deoxyribose + phosphate group + cytosine.
