Questions: Carries amino acids to the ribosomes Carries information from the nucleus to the cytoplasm Contains anticodons Located only in the cytoplasm Carries a complementary copy of a gene Short, singlestranded chain of nucleotides with occasional areas of intramolecular binding Contains codons tRNA (1/2) mRNA (2/2)

The question appears to be about the roles and characteristics of tRNA (transfer RNA) and mRNA (messenger RNA) in the process of protein synthesis. Let's address each statement and determine whether it pertains to tRNA or mRNA.

1. Carries amino acids to the ribosomes:

   • The answer is tRNA. tRNA molecules are responsible for transporting amino acids to the ribosome during translation.

2. Carries information from the nucleus to the cytoplasm:

   • The answer is mRNA. mRNA carries the genetic information transcribed from DNA in the nucleus to the ribosomes in the cytoplasm, where it is translated into a protein.

3. Contains anticodons:

   • The answer is tRNA. tRNA molecules have anticodons, which are sequences of three nucleotides that are complementary to the codons on the mRNA strand.

4. Located only in the cytoplasm:

   • The answer is tRNA. tRNA is found in the cytoplasm where it participates in translation. mRNA, on the other hand, is synthesized in the nucleus and then transported to the cytoplasm.

5. Carries a complementary copy of a gene:

   • The answer is mRNA. mRNA is synthesized as a complementary copy of a gene during transcription.

6. Short, single-stranded chain of nucleotides with occasional areas of intramolecular binding:

   • The answer is tRNA. tRNA is a short, single-stranded RNA molecule that folds into a characteristic cloverleaf structure due to intramolecular base pairing.

7. Contains codons:

   • The answer is mRNA. mRNA contains codons, which are sequences of three nucleotides that specify particular amino acids during translation.

Summarizing the answers:

• tRNA: Carries amino acids to the ribosomes, contains anticodons, located only in the cytoplasm, short, single-stranded chain of nucleotides with occasional areas of intramolecular binding.
• mRNA: Carries information from the nucleus to the cytoplasm, carries a complementary copy of a gene, contains codons.
