Question
complete the table to compare dna and rna.
table with columns: (blank), dna, rna; rows: found in the cytoplasm, contains the genetic instructions for making all the proteins an organism needs, found in the nucleus, helps carry out genetic instructions in the cell; each cell in dna/rna columns has a checkbox
Response
To solve this, we analyze the characteristics of DNA and RNA:
1. "found in the cytoplasm"
- DNA: Mainly in the nucleus (small amounts in mitochondria/chloroplasts), so No (uncheck).
- RNA: Types like mRNA, tRNA, rRNA are in the cytoplasm (and nucleus during transcription), so Yes (check).
2. "contains the genetic instructions for making all the proteins an organism needs"
- DNA: Stores the genetic code (genes) for protein synthesis, so Yes (check).
- RNA: Carries DNA’s instructions (e.g., mRNA) but does not store the original genetic blueprint for all proteins, so No (uncheck).
3. "found in the nucleus"
- DNA: Primarily located in the nucleus (as chromatin/chromosomes), so Yes (check).
- RNA: Transcribed in the nucleus (e.g., mRNA) and then moves to the cytoplasm, so Yes (check, as RNA is present in the nucleus during transcription).
4. "helps carry out genetic instructions in the cell"
- DNA: Stores instructions but does not directly carry out protein synthesis (passive storage), so No (uncheck).
- RNA: mRNA carries the code, tRNA delivers amino acids, rRNA forms ribosomes—all essential for protein synthesis, so Yes (check).
Filled Table:
| Characteristic | DNA | RNA |
|---|---|---|
| contains the genetic instructions for making all the proteins an organism needs | ☑ | ☐ |
| found in the nucleus | ☑ | ☑ |
| helps carry out genetic instructions in the cell | ☐ | ☑ |
(Note: For each row, mark "☑" if true, "☐" if false.)
