Give the complementary DNA strand for the following:

Question

ATC GCT AAT
(1 point)
UAG CGA UUA
TAG CGA TTA
ATC GCT AAT
GCT ATC GGC

Answer 1

To find the complementary DNA strand for the given sequence "ATC GCT AAT," we need to match each base with its complement. The complementary bases are:

• A (adenine) pairs with T (thymine)
• T (thymine) pairs with A (adenine)
• C (cytosine) pairs with G (guanine)
• G (guanine) pairs with C (cytosine)

Now, let's find the complementary strand:

1. A → T
2. T → A
3. C → G
4. G → C
5. C → G
6. T → A
7. A → T
8. T → A

So, the complementary DNA strand for "ATC GCT AAT" is:

TAG CGA TTA

Therefore, the correct answer is: TAG CGA TTA.
