Question

been shown \unwound.\ color the sugars - yellow and the phosphates - green. hint: look at the nucleotide for help. 3. the stair steps are nitrogen bases bonded together with hydrogen using the base pairing rule. the bases are guanine, cytosine, thymine and adenine. guanine and cytosine always bond together. (g - c) thymine and adenine always bond together. (t - a) label the empty bases. color the bases as follows: guanine (g) - blue cytosine (c) - red thymine (t) - orange adenine (a) - purple 4. draw a circle around a single thymine nucleotide.

Explanation:

This is a task related to the structure of DNA. It involves coloring and labeling parts of the DNA molecule based on knowledge of nucleotides (sugars, phosphates, and nitrogen - bases) and base - pairing rules.

Answer:

1. Color the sugar - containing parts of the DNA yellow and the phosphate - containing parts green.
2. Use the base - pairing rules (G - C and T - A) to label the empty nitrogen bases on the DNA model. Color guanine blue, cytosine red, thymine orange, and adenine purple.
3. Draw a circle around a single thymine nucleotide on the DNA model.
