Latest Update (2025/2026) Guaranteed Pass
1. DNA pentose sugar is called:: 2-deoxyribose
2. RNA pentose sugar is called:: ribose
3. nucleoside: base + sugar (missing phosphate group)
4. nucleotide: base + sugar + phosphate group
5. G binds to: C with 3 hydrogen bonds
6. A binds to: T with 2 hydrogen bonds
(or U in RNA)
7. Codon: three-nucleotide sequence on messenger RNA that codes
for a single amino acid
8. True/False:
Transcription of mRNA into DNA requires an RNA primer.: False
9. Which type of cell has more DNA-prokaryotes or eukaryotes?:
Eukaryotes 10. What happens to complexes during DNA

replication?: Complexes relax due to histone proteins dissociating
and when replication ends, histone proteins tighten and DNA
condenses.
11. Ribosomes: Serves as a site for protein
12. Shelterin complex: Protects chromosome ends from
degradation
13. Reverse transcription: synthesis of DNA from RNA
template
14. Exon: mRNA sequences that are ending
15. wobble hypothesis: the hypothesis that some tRNA
molecules can pair with more than one mRNA codon, tolerating
some variations in the third base, as long as the first and second
bases are correctly matched
16. degeneracy of the genetic code: most amino acids are not
specified by a single codon
17. Pribnow element: cis-acting
18. Where is Pribnow element located?: upstream from the
site of transcription
