To find the complementary DNA strand, we first need to understand the base pairing rules of DNA. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
Now, let’s break down the sequence you provided for its complementary strand:
- For the first segment, ATGC:
- A pairs with T
- T pairs with A
- G pairs with C
- C pairs with G
So, the complement is TACG.
- For the second segment, ATGC:
- A pairs with T
- T pairs with A
- G pairs with C
- C pairs with G
The complement is again TACG.
- For the third segment, CGTA:
- C pairs with G
- G pairs with C
- T pairs with A
- A pairs with T
The complement is GCAT.
- For the fourth segment, TACG:
- T pairs with A
- A pairs with T
- C pairs with G
- G pairs with C
The complement is ATGC.
Combining all the complementary strands together, we get:
TACG TACG GCAT ATGC
This is the complete complementary DNA strand for the given sequence.
