17. CGA-GAG-TCT-CTA
For the first given sequence, "AGT-GTG-CAC-ACT," we can match each base with its complement as follows:
A - T
G - C
T - A
G - C
C - G
A - T
C - G
T - A
So, the complementary DNA strand for "AGT-GTG-CAC-ACT" is "TCA-CAC-GTG-TGA."
Similarly, for the second given sequence, "GCT-CTC-AGA-GAT," we can match each base with its complement as follows:
G - C
C - G
T - A
C - G
A - T
G - C
A - T
T - A
So, the complementary DNA strand for "GCT-CTC-AGA-GAT" is "CGA-GAG-TCT-CTA."
Let's start with the first sequence, "AGT-GTG-CAC-ACT" (sequence 16). To create the complementary DNA strand, you will need to replace each base with its complementary base.
A (adenine) pairs with T (thymine)
G (guanine) pairs with C (cytosine)
T (thymine) pairs with A (adenine)
G (guanine) pairs with C (cytosine)
C (cytosine) pairs with G (guanine)
A (adenine) pairs with T (thymine)
C (cytosine) pairs with G (guanine)
A (adenine) pairs with T (thymine)
T (thymine) pairs with A (adenine)
So the complementary DNA strand for "AGT-GTG-CAC-ACT" (sequence 16) is "TCA-CAC-GTG-TGA".
Now let's move on to the second sequence, "GCT-CTC-AGA-GAT" (sequence 17).
G (guanine) pairs with C (cytosine)
C (cytosine) pairs with G (guanine)
T (thymine) pairs with A (adenine)
C (cytosine) pairs with G (guanine)
A (adenine) pairs with T (thymine)
G (guanine) pairs with C (cytosine)
A (adenine) pairs with T (thymine)
T (thymine) pairs with A (adenine)
So the complementary DNA strand for "GCT-CTC-AGA-GAT" (sequence 17) is "CGA-GAG-TCT-CTA".
Remember, the process of creating a complementary DNA strand requires replacing each base with its complementary base according to the base-pairing rules.
