Chapter 23, Problem 13
If the sequence T-A-C-C-G-A appeared on one strand of DNA, what sequence would appear opposite it on the other strand?
Verified step by step guidance1
Step 1: Understand that DNA is composed of two strands that form a double helix, where each strand is complementary to the other.
Step 2: Recall the base pairing rules in DNA: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
Step 3: Start with the first base of the given sequence, which is Thymine (T), and find its complementary base, which is Adenine (A).
Step 4: Move to the next base in the sequence, which is Adenine (A), and find its complementary base, which is Thymine (T).
Step 5: Continue this process for each base in the sequence: C pairs with G, C pairs with G, G pairs with C, and A pairs with T, to determine the full complementary sequence.

Spermaceti, a fragrant substance isolated from sperm whales, was a common ingredient in cosmetics until its use was banned in 1976 to protect the whales from extinction. Chemically, spermaceti is cetyl palmitate, the ester of palmitic acid with cetyl alcohol (the straight-chain C16 alcohol). Show the structure of spermaceti.
