Problem Analysis:
The image provided illustrates the processes of
transcription and
translation, which are key steps in gene expression. The task is to label the diagram using the given color code and identify the components involved in these processes.
#### Key Components in the Diagram:
1.
Transcription (Left Side):
- Occurs in the nucleus.
- Involves the synthesis of mRNA from DNA.
- The mRNA is then transported out of the nucleus into the cytoplasm.
2.
Translation (Right Side):
- Occurs in the cytoplasm on ribosomes.
- Involves the assembly of amino acids into a protein based on the sequence of mRNA.
#### Color Code Provided:
-
DNA: Yellow
-
mRNA: Light blue
-
Thymine: Orange
-
Adenine: Green
-
Guanine: Purple
-
Cytosine: Yellow
-
Uracil: Brown
-
Nucleus: Gray
-
Ribosome: Light green
-
tRNA: Red
-
Amino acids: Black
Solution:
#### Step 1: Labeling the Left Side (Transcription)
-
D: DNA (Yellow)
- This represents the double-stranded DNA molecule in the nucleus.
-
E: mRNA (Light blue)
- This is the single-stranded RNA molecule being transcribed from the DNA template.
-
X: Nucleus (Gray)
- The region where transcription occurs.
#### Step 2: Labeling the Right Side (Translation)
-
Y: Ribosome (Light green)
- The site where translation occurs, assembling amino acids into a protein.
-
F: tRNA (Red)
- Transfer RNA molecules that bring specific amino acids to the ribosome.
-
M: Amino acids (Black)
- The building blocks of proteins, attached to tRNA molecules.
-
X: Cytoplasm (Not explicitly colored, but the region outside the nucleus where translation occurs).
#### Final Labels:
-
Left Side (Transcription):
-
D: DNA (Yellow)
-
E: mRNA (Light blue)
-
X: Nucleus (Gray)
-
Right Side (Translation):
-
Y: Ribosome (Light green)
-
F: tRNA (Red)
-
M: Amino acids (Black)
-
X: Cytoplasm (Not explicitly colored)
Explanation:
1.
Transcription:
- DNA (Yellow) serves as the template for mRNA synthesis.
- mRNA (Light blue) is synthesized and exits the nucleus through nuclear pores.
- The nucleus (Gray) is the location where transcription occurs.
2.
Translation:
- The ribosome (Light green) is the site of protein synthesis.
- tRNA (Red) carries specific amino acids (Black) to the ribosome based on the codons in the mRNA.
- The process occurs in the cytoplasm (not explicitly colored but indicated by the surrounding area).
Final Answer:
\[
\boxed{
\begin{aligned}
&\text{Left Side:} \\
&\text{D: DNA (Yellow)} \\
&\text{E: mRNA (Light blue)} \\
&\text{X: Nucleus (Gray)} \\
&\text{Right Side:} \\
&\text{Y: Ribosome (Light green)} \\
&\text{F: tRNA (Red)} \\
&\text{M: Amino acids (Black)} \\
&\text{X: Cytoplasm (Not explicitly colored)}
\end{aligned}
