Q15.99P - Chemistry: Molecular Nature Of Matter And Change

Question

Write the sequence of the complementary DNA strand that pairs with each of the following DNA base sequences:

(a) GGTTAC 

(b) CCCGAA

Step-by-Step Solution

Answer

1. The complementary DNA stand for the GGTTAC DNA base sequence is CCAATG.
2. The complementary DNA stand for the CCCGAA DNA base sequence is GGGCTT.

Step 1:(a) DNA base sequence of GGTTAC

Each base is partnered with the same partner at all times. As a result, the complement of one chain's base sequence equals the complement of the other chain's base sequence.

CCAATG is the complementary DNA stand that matches with the GGTTAC DNA base sequence.

Step2:(b) DNA base sequence of CCCGAA

GGGCTT is the complementary DNA stand that matches with the CCCGAA DNA base sequence.
