Across
- 3. the enzyme that lays down RNA primer to start DNA replication
- 6. nitrogenous bases that have two rings
- 13. chromatin located in the centromeres and telomeres that is not typically transcribed
- 14. the enzyme that ligates the fragments from the lagging strand
- 18. the main enzyme used in DNA replication
- 19. these fragments occur on the lagging strand due to noncontinuous replication
- 21. the enzyme that relaxes supercoiling
- 22. a molecule with repeating units
- 23. a virus that attacks a bacteria
- 26. proteins that stabilize separated DNA strands and prevent it from coming back together during replication
- 28. a pentose sugar found in RNA
- 29. dispensable minor chromosomes located in prokaryotes
- 30. a complex of DNA and chromosomal protein
Down
- 1. DNA bound around a histone is called this and multiple look like beads on a string
- 2. in what way/direction is DNA replicated
- 4. the bases of DNA strands are connected by this
- 5. these organisms typically have a circular chromosome
- 7. the two strands of DNA are arranged in this way
- 8. type of chromatin that undergoes change during cell cyle and is actively transcribed
- 9. DNA replication is know to follow this type of model in which parental DNA strand is used as a template
- 10. the total amount of DNA in the haploid species is known as this
- 11. the bond that connects nucleotides on the same DNA strand
- 12. the enzyme that unwinds DNA
- 15. the phase in which DNA is most condensed
- 16. a pentose sugar found in DNA
- 17. contains a sugar and a base
- 20. a pyrimidine only found in RNA
- 24. the abundant protein found in DNA for condensing
- 25. the enzyme that has 5'-3' exonuclease activity and removes RNA primer and replaces it with DNA
- 27. site where DNA strands separate to initiate replication is
