Question

complete the table to compare dna and rna.
table with rows: found in the cytoplasm, helps carry out genetic instructions in the cell, found in the nucleus, contains the genetic instructions for making all the proteins an organism needs; columns dna, rna with checkboxes

Explanation:

To complete the table, we use the following knowledge about DNA and RNA:

1. Found in the cytoplasm: RNA (like mRNA, tRNA, rRNA) is found in the cytoplasm. DNA is mainly in the nucleus (except for some in mitochondria/chloroplasts, but generally not cytoplasm). So DNA: no (uncheck), RNA: yes (check).
2. Helps carry out genetic instructions: RNA is involved in translation (carrying out protein synthesis from DNA's instructions). DNA holds the instructions but doesn't carry them out. So DNA: no (uncheck), RNA: yes (check).
3. Found in the nucleus: DNA is primarily in the nucleus. RNA is synthesized in the nucleus and then moves to the cytoplasm, but some RNA (like pre - mRNA) can be in the nucleus. However, DNA is mainly in the nucleus. So DNA: yes (check), RNA: yes (check) (since RNA is made in the nucleus and can be present there temporarily).
4. Contains genetic instructions for proteins: DNA contains the genetic code (genes) that have instructions for making all proteins an organism needs. RNA is a copy of a part of DNA (gene) and is involved in protein synthesis but doesn't contain the full set of instructions for all proteins. So DNA: yes (check), RNA: no (uncheck).

Answer:

	DNA	RNA
helps carry out genetic instructions in the cell	$\square$ (uncheck)	$\blacksquare$ (check)
found in the nucleus	$\blacksquare$ (check)	$\blacksquare$ (check)
contains the genetic instructions for making all the proteins an organism needs	$\blacksquare$ (check)	$\square$ (uncheck)
