Find the complimentary DNA sequence after going through DNA replication…

1) AAGTCCAT a) ACTGAATG

2) TGACTTAC b) CGGAGTTT

3) GCCTCAAA c) TTCAGGTA

Adenine pairs with Thymine. Guanine pairs with Cytosine.

So if you see an A, the complimentary nucleobase would be T. For Guanine, the complimentary base would be C.

So, 1-c, 2-a, 3-b

thank you.

To find the complementary DNA sequence after DNA replication, we need to first understand the concept of base pairing. In DNA, there are four nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). A always pairs with T, and C always pairs with G. During DNA replication, the original DNA strand serves as a template for the synthesis of a new complementary strand.

Let's analyze each given sequence to find its complementary DNA sequence:

1) AAGTCCAT:
To find the complementary DNA sequence, we need to replace each base with its complementary base. A pairs with T, C pairs with G, and vice versa. Therefore, the complement of AAGTCCAT is TTCAGGTA. So, the correct answer is c) TTCAGGTA.

2) TGACTTAC:
Using the same principle of base pairing, we can find the complementary DNA sequence for TGACTTAC. T pairs with A, G pairs with C, and vice versa. Therefore, the complement of TGACTTAC is ACTGAATG. So, the correct answer is a) ACTGAATG.

3) GCCTCAAA:
Once again, applying the base pairing concept, we can determine the complementary DNA sequence for GCCTCAAA. G pairs with C, C pairs with G, A pairs with T, and vice versa. Therefore, the complement of GCCTCAAA is CGGAGTTT. So, the correct answer is b) CGGAGTTT.

In summary:
1) AAGTCCAT -> TTCAGGTA (c)
2) TGACTTAC -> ACTGAATG (a)
3) GCCTCAAA -> CGGAGTTT (b)
