6 Questions
True or false: Purines normally always base-pair with pyrimidines in DNA
True
True or false: Purines consist of adenine and guanine?
True
True or false: DNA is single-stranded?
False
What is the significance of tRNA's structure in relation to its function?
The specific structure of tRNA allows it to carry a specific amino acid and recognize the corresponding codon on mRNA during protein synthesis, facilitating the accurate translation of the genetic code.
Explain why tRNA looks like a 't'.
tRNA looks like a 't' due to its cloverleaf structure, with one arm forming a loop that resembles the vertical line of the letter 't', and another arm extending out to one side resembling the horizontal line.
How does tRNA's shape contribute to its role in protein synthesis?
The unique shape of tRNA enables it to bind to both an amino acid and mRNA, positioning the amino acid in the correct sequence during protein synthesis and ensuring the accurate assembly of the polypeptide chain.
Study Notes
DNA Base Pairing
- Purines (adenine and guanine) always base-pair with pyrimidines (cytosine and thymine) in DNA, following the rules of complementary base pairing.
tRNA Structure
- tRNA (transfer RNA) has a cloverleaf structure that resembles a "t" shape, which allows it to perform its function of transporting amino acids to the ribosome during protein synthesis.
