Problem Description:

The task involves coloring a DNA and mRNA structure according to specific instructions provided in the image. The goal is to identify and color different components of the nucleotides (phosphates, deoxyribose, bases) and hydrogen bonds, as well as differentiate between DNA and mRNA.

Solution Explanation:

#### Step 1: Understand the Components
1. DNA Structure:
- DNA is composed of two strands forming a double helix.
- Each strand consists of repeating units called nucleotides.
- A nucleotide has three parts:
- Phosphate group (colored pink).
- Deoxyribose sugar (colored blue).
- Nitrogenous base (colored differently based on type):
- Thymine (T): Orange.
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Hydrogen bonds (between complementary bases) are colored grey.

2. mRNA Structure:
- mRNA is a single-stranded molecule.
- Similar to DNA, but with some differences:
- Uses ribose instead of deoxyribose (colored darker blue).
- Contains uracil (U) instead of thymine (colored brown).

#### Step 2: Follow the Coloring Instructions
- DNA:
- Color all phosphates pink.
- Color all deoxyribose sugars blue.
- Color the nitrogenous bases as follows:
- Thymine (T): Orange.
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Color the hydrogen bonds grey.

- mRNA:
- Follow the same steps as for DNA, but:
- Color the ribose sugar darker blue.
- Color uracil (U) brown instead of thymine.

#### Step 3: Apply the Coloring
Using the provided diagram:
1. DNA Double Helix:
- Identify and color all phosphates pink.
- Identify and color all deoxyribose sugars blue.
- Identify and color the bases:
- Thymine (T): Orange.
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Draw grey lines to represent hydrogen bonds between complementary bases (e.g., A-T, G-C).

2. mRNA Single Strand:
- Identify and color all phosphates pink.
- Identify and color all ribose sugars darker blue.
- Identify and color the bases:
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Uracil (U): Brown.

#### Step 4: Verify the Coloring
- Ensure that all components are correctly identified and colored according to the instructions.
- Double-check the hydrogen bonds in the DNA double helix to ensure they are drawn between complementary bases.

#### Final Answer:
The final colored diagram should look like the one shown in the image, with all components correctly labeled and colored as per the instructions. If you need a detailed description of the coloring, here it is:

- DNA:
- Phosphates: Pink.
- Deoxyribose: Blue.
- Bases:
- Thymine (T): Orange.
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Hydrogen bonds: Grey.

- mRNA:
- Phosphates: Pink.
- Ribose: Darker blue.
- Bases:
- Adenine (A): Green.
- Guanine (G): Purple.
- Cytosine (C): Yellow.
- Uracil (U): Brown.

Thus, the task is completed by following these steps and ensuring accuracy in coloring.
