Question

one strand of dna is read as 5 acg 3 what is the corresponding strand? 5 tgc 3 3 tgc 5 question 6 which is the 3 end of the parental strand of dna? c a

Explanation:

In DNA, base - pairing rules apply (A pairs with T, C pairs with G). Also, DNA strands are anti - parallel. For the first question, if one strand is \(5'\text{ACG}3'\), the complementary bases are \(TGC\), and because of the anti - parallel nature, the corresponding strand is \(3'\text{TGC}5'\). For the second question, without seeing the full context of the diagram (but based on common DNA replication diagrams), during DNA replication, the parental strand has a \(3'\) end which is often at a specific location (in many replication fork diagrams, the \(3'\) end of the parental strand is where the replication machinery can act in a certain orientation, and if \(A\) is marked as the \(3'\) end in the given diagram, it follows the standard anti - parallel and replication - related strand orientation concepts).

Answer:

For the first question: \(3'\text{TGC}5'\) is the correct strand. For the second question: If the answer is \(A\) (assuming the diagram's context where \(A\) is marked as the \(3'\) end of the parental strand based on standard DNA replication strand orientation).
