Complete the following DNA strand to this sequence: ATT/GCC/AAT/GAT
Understand the Problem
The question is asking to complete a DNA strand that follows the base pairing rules. This involves understanding which nucleotides pair with each other to provide the correct complementary sequence.
Answer
TAA/CGG/TTA/CTA
Answer for screen readers
The completed DNA strand is: TAA/CGG/TTA/CTA.
Steps to Solve
-
Identify the base pairing rules for DNA DNA bases pair as follows: Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C).
-
Analyze the given DNA strand The provided sequence is: ATT/GCC/AAT/GAT. We will find the complementary bases for each segment.
-
Pair bases for the first segment For the first segment "ATT":
- A pairs with T
- T pairs with A
- T pairs with A Thus, the complement is TAA.
- Pair bases for the second segment For the second segment "GCC":
- G pairs with C
- C pairs with G
- C pairs with G Thus, the complement is CGG.
- Pair bases for the third segment For the third segment "AAT":
- A pairs with T
- A pairs with T
- T pairs with A Thus, the complement is TTA.
- Pair bases for the fourth segment For the last segment "GAT":
- G pairs with C
- A pairs with T
- T pairs with A Thus, the complement is CTA.
The completed DNA strand is: TAA/CGG/TTA/CTA.
More Information
This process demonstrates the complementary nature of DNA, where each nucleotide on one strand determines the nucleotide on the opposing strand according to specific pairing rules.
Tips
- Confusing base pairs (e.g., pairing A with G instead of T).
- Forgetting to complete all segments or leaving spaces empty.
