Biochemistry ACS Questions and
Correct Answers the Latest Update
DNA

✓ carry genetic information, double-stranded, more stable



RNA

✓ intermediate of gene expression, single-stranded, less stable



tRNA

✓ transfer RNA, holds amino acid for protein synthesis



wobble position

✓ looser binding, pairing of 3rd codon less critical



inosine

✓ closely resembles G, can pair with A, U, or C, allows tRNA flexibility



rRNA

✓ ribosome RNA, makes up ribosomes



siRNA

✓ small interfering RNA, double-stranded, mRNA degradation
