Using the base pairing rules, what is the correct matching DNA sequence for this sample strand: TTACGCAT.

finlep [7]

Answer:

According to base pairing rule- Adenine pair with thymine(A=T) and Guanine pair with Cytosine(G≡C).

Explanation:

According Chargaffs rule for base pairing-

ADENINE=THYMINE and GUANINE≡ CYTOSINE.

If we consider it as 5' to 3' like- 5' TTACGCAT 3'. Then correct matched codon on other strand will be- 3' AATGCGTA 5'
