Verified step by step guidance
1
Identify the components of a nucleotide: a nucleotide consists of a phosphate group, a deoxyribose sugar, and a nitrogenous base. In this case, the base is thymine (dTMP).
Understand the structure of deoxyribose: deoxyribose is a five-carbon sugar with the formula C5H10O4. It is part of the backbone of DNA, connecting to the phosphate group and the nitrogenous base.
Recognize the phosphodiester bond: this bond links the 3' carbon atom of one sugar molecule to the 5' carbon of another, forming the backbone of the DNA strand.
Draw the first nucleotide: start with the deoxyribose sugar, attach the thymine base to the 1' carbon, and add a phosphate group to the 5' carbon.
Connect the nucleotides: link the 3' carbon of the first nucleotide to the 5' phosphate of the next nucleotide using a phosphodiester bond. Repeat this process to connect three nucleotides in total, ensuring each has a thymine base.
