To match the DNA strands to their complementary portions, we need to know that DNA strands pair with each other according to base pairing rules: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
Given the strands:
- ATCCGGAAT
- TACGGCTTA
- ATCCGGATT
- ATGGCCAAT
And the complementary strands:
- ATGCCGAAT
- TAGGCCTAA
- TACCGGTTA
- TAGGCCTTA
Matching:
-
ATCCGGAAT ↔ TAGGCCTTA
- ATCCGGAAT → TAGGCCTTA is the complement (A↔T, T↔A, C↔G, C↔G, G↔C, G↔C, A↔T, A↔T).
-
TACGGCTTA ↔ ATCCGGAAT
- TACGGCTTA → ATCCGGAAT is the complement.
-
ATCCGGATT ↔ TAGGCCTAA
- ATCCGGATT → TAGGCCTAA (complimentary pairing AT-TA, CC-GG, G-C).
-
ATGGCCAAT ↔ TACCGGTTA
- ATGGCCAAT ↔ TACCGGTTA (AT-TA, GG-CC, CC-GG).
Summary of Matches:
- ATCCGGAAT matches with TACGGCTTA
- TACGGCTTA matches with ATCCGGAAT
- ATCCGGATT matches with TAGGCCTAA
- ATGGCCAAT matches with TACCGGTTA
Since TACGGCTTA and ATCCGGAAT are actually the same pairs, you can only match one pair correctly based on what was provided.
