RNA Base Pairing Worksheet with DNA double helix diagram and nucleotide sequences for learning base pairing rules.

Problem Description:

The task involves determining the sequence of a new strand of RNA (mRNA) based on the given DNA template strand. The rules for RNA base pairing are as follows:
1. DNA to RNA: When RNA is synthesized from DNA, only those bases that match with the original DNA strand are included.
2. Base Pairing Rules:
- In translation, adenine (A) in RNA pairs with uracil (U) in tRNA.
- Cytosine (C) pairs with guanine (G).
- Guanine (G) pairs with cytosine (C).
- Adenine (A) pairs with uracil (U).

The problem provides four DNA sequences, and we need to determine the corresponding RNA sequences using the base pairing rules.

Solution:

#### Step 1: Understand the Base Pairing Rules
- DNA to RNA Conversion:
- DNA: A → U (in RNA)
- DNA: T → A (in RNA)
- DNA: C → G (in RNA)
- DNA: G → C (in RNA)

#### Step 2: Apply the Rules to Each DNA Sequence

- Convert each DNA base to its complementary RNA base:
- A → U
- T → A
- C → G
- G → C
