Question

dna replication copies dna to produce two identical dna molecules. base - pairing rules a - t g - c dna replication is semiconservative, meaning each copied dna will have an original nucleotide strand and a new nucleotide strand. the original strand acts as a template for the new strand. directions: drag and drop the bases to replicate this dna ladder. remember that strands are antiparallel.

Explanation:

Step1: Recall Base - Pairing Rules

The base - pairing rules for DNA are \(A - T\) (Adenine pairs with Thymine) and \(G - C\) (Guanine pairs with Cytosine). Also, the strands are antiparallel. Let's start with the topmost base on the left - hand original strand, which is \(A\). According to \(A - T\), we need to pair \(A\) with \(T\). Looking at the available bases in the drag - and - drop area, we have \(T\) (cyan color).

Step2: Next Base on Left Strand

The next base on the left original strand (below \(A\)) is \(G\). Using the \(G - C\) rule, we need to pair \(G\) with \(C\). The available \(C\) (green color) can be used here.

Step3: Continue for Remaining Bases

We continue this process for each base on the original strands (both left and right) by applying the \(A - T\) and \(G - C\) base - pairing rules. For example, if there is a \(T\) on the original strand, we pair it with \(A\), and if there is a \(C\), we pair it with \(G\), while also keeping in mind the antiparallel nature of the strands (the direction of the new strand is opposite to the original strand, but for the base - pairing, the rule is still \(A - T\) and \(G - C\)).

Answer:

To solve the DNA replication base - pairing, we use the base - pairing rules \(A - T\) and \(G - C\). For each base on the original DNA strands:

• Pair \(A\) (yellow) with \(T\) (cyan).
• Pair \(T\) (cyan) with \(A\) (yellow).
• Pair \(G\) (pink) with \(C\) (green).
• Pair \(C\) (green) with \(G\) (pink).

By following these rules and the antiparallel strand direction, we can correctly drag and drop the bases (\(A\), \(T\), \(G\), \(C\)) to replicate the DNA ladder. The final paired DNA will have each \(A\) matched with \(T\) and each \(G\) matched with \(C\) on the new strands, maintaining the semiconservative nature of DNA replication.
