DNA STRAND

Choose the letter of the correct answer:

The following is the base sequence on one strand of a DNA molecule: A A T G C C A G T G G T "If this strand is replicated", which of the following is the complementary strand that is produced?

• A. T C G T C C G T C T A G
• B. A G C A G G C A G G G T
• C. T T A C G G T C A C C A
• D. U C G U C C U C U A G A

Explanation:

The complementary base pairing rule states that Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C). Therefore, the complementary strand to the given base sequence will be:

• T T A C G G T C A C C A

Verified answer

Answer:

If the DNA molecule “A A T G C C A G T G G T” is replicated, its complementary strand will be is “T T A C G G T C A C C A”. Therefore, the answer is “c. T T A C G G T C A C C A”.

Explanation:

Each of these nitrgenous bases has a complementary bases.

Adenine (A) = Thymine (T)

Cytosine (C) = Guanine (G)

These are the four nitrogenous bases and their complementary bases of a DNA molecule.

Nitrogenous base is a part of a nucleotide. There are 3 parts of nucleotides, and these are:

1. Sugar
2. Phospate group
3. Nitrogenous base
