What would be the complementary sequence for a DNA base sequence of AGCTAG?

Explanation:
The complementary sequence for a DNA base sequence is determined by the base pairing rules, where adenine pairs with thymine and cytosine pairs with guanine. Given the original DNA sequence of AGCTAG, we can find the complementary bases as follows: - A (adenine) pairs with T (thymine), - G (guanine) pairs with C (cytosine), - C (cytosine) pairs with G (guanine), - T (thymine) pairs with A (adenine), - A (adenine) pairs with T (thymine), and - G (guanine) pairs with C (cytosine). So, the complementary sequence for AGCTAG would be: - A → T - G → C - C → G - T → A - A → T - G → C This results in the sequence TCGATC. This sequence accurately reflects the base pairing in DNA, confirming that it is the correct complementary sequence for the given DNA base sequence.

The complementary sequence for a DNA base sequence is determined by the base pairing rules, where adenine pairs with thymine and cytosine pairs with guanine. Given the original DNA sequence of AGCTAG, we can find the complementary bases as follows:

  • A (adenine) pairs with T (thymine),

  • G (guanine) pairs with C (cytosine),

  • C (cytosine) pairs with G (guanine),

  • T (thymine) pairs with A (adenine),

  • A (adenine) pairs with T (thymine), and

  • G (guanine) pairs with C (cytosine).

So, the complementary sequence for AGCTAG would be:

  • A → T

  • G → C

  • C → G

  • T → A

  • A → T

  • G → C

This results in the sequence TCGATC. This sequence accurately reflects the base pairing in DNA, confirming that it is the correct complementary sequence for the given DNA base sequence.
