Okay, now I see the bottom half of the diagram clearly. This section illustrates translation, where the mRNA is being read to synthesize a protein. The structure labeled "C" is the cytoplasm, as this is where translation occurs in eukaryotic cells. The arrow labeled "D" points from the transcription process to the translation process, indicating the movement of mRNA from the nucleus to the cytoplasm.
Looking at the numbered labels:
-
6 points to the large, oval-shaped structure that is reading the mRNA. This is the "ribosome", which is the molecular machine that facilitates translation.
-
7 points to the single-stranded RNA molecule that is being read by the ribosome. Since it's the template for translation, this is "mRNA (translation)".
-
8 points to a tRNA molecule that is not carrying an amino acid. This is "tRNA without amino acid".
-
9 points to the growing chain of amino acids. This is the "peptide" chain.
-
10 points to the sequence of three nucleotides on the mRNA that codes for a specific amino acid. This is a "codon".
-
11 points to the part of the tRNA that pairs with the codon on the mRNA. This is the "anticodon".
-
12 points to a tRNA molecule that is carrying an amino acid. This is "tRNA with amino acid".
-
13 points to the amino acid attached to the tRNA. This is simply an "amino acid".
I have identified all the parts in the bottom half. Now, I will compile the final answer.
Final Answer
Here are the correct labels for the diagram:
A: nucleus
B: mRNA (transcription)
C: cytoplasm
D: translation
1: mRNA (transcription)
2: DNA - template strand
3: DNA - coding strand
4: RNA polymerase
5: nucleotide
6: ribosome
7: mRNA (translation)
8: tRNA without amino acid
9: peptide
10: codon
11: anticodon
12: tRNA with amino acid
13: amino acid
This completes the labeling of the diagram according to the provided word list.
