True or false: in translation, complimentary nucleotides are matched and converted into amino acid sequence. False; in translation codon nucleotides are bound directly to amino acids False; in translation nucleotides are matched by complementarity but amino acid sequence is unrelated True; codons matching anti-codons is the only process where complimentary nucleotides associate True; nucleotides on mRNA and on tRNA are complimentary (the operon and anti-codon) and the tRNA carries a single amino acid

Which part of the nucleotide stabilizes the structure of DNA using weak van der Waals interactions (stacking) and using hydrogen bonds? (Note that covalent bonds are not included in that sentence.) a. the deoxyribose sugar b. the ribose sugar c. the phosphate d. the nitrogenous base e. the amino acid Question 2b This ability of the nitrogenous bases to exist in more than one form can lead to incorporation of...
