Let's evaluate each statement:
-
In eukaryotes, DNA is found in the cytoplasm of the cell.
- False. In eukaryotes, DNA is primarily found in the nucleus, not the cytoplasm.
-
RNA is the nucleic acid that helps build proteins.
- True. RNA, particularly messenger RNA (mRNA), is involved in the process of translating the genetic code into proteins.
-
DNA is the nucleic acid that carries genetic information.
- True. DNA (deoxyribonucleic acid) carries the genetic information necessary for the growth, development, and reproduction of all living organisms.
-
The structure of proteins is determined by DNA.
- True. The sequence of nucleotides in DNA specifies the amino acid sequence of proteins, thus determining their structure.
-
A chromosome is made of RNA.
- False. Chromosomes are made of DNA and histone proteins, not RNA.
Based on this evaluation, the true statements are:
- RNA is the nucleic acid that helps build proteins.
- DNA is the nucleic acid that carries genetic information.
- The structure of proteins is determined by DNA.
