Molecular Genetics
Across
- 1. This type of RNA is used to make ribosomes.
- 3. Fragment end of DNA that is fully base-paired after having been cleaved by a restriction enzyme.
- 6. 5' caps added onto transcripted DNA are made of this.
- 7. This type of mutation results from base pairs switching sides; is the cause of sickle cell anemia.
- 9. This sequence of DNA binds RNA polymerase to initiate transcription.
- 10. This scientist discovered the base-pairing rule for DNA.
- 11. Enzymes that are able to cleave double stranded DNA into fragments.
- 15. A cluster of structural genes located on bacterial chromosomes.
- 16. Coding region of DNA.
- 17. Small circular pieces of DNA that can enter and exit bacteria.
- 18. Adenine and thymine belong to this group of nucleotides.
- 19. The third and final step of transcription.
Down
- 1. A protein that releases a finished polypeptide from the ribosome after translation is completed.
- 2. This enzyme removes the introns from the transcripted DNA.
- 4. Replicating strand that is not synthesized continuously.
- 5. A structure level of DNA that involves a 3D shape with major and minor grooves along its length.
- 8. In translation, the mRNA start codon enters this site for translation to begin.
- 12. This is the coding region of DNA in transcription.
- 13. Enzyme that unwinds the DNA helix by severing H-bonds.
- 14. Three bases that serve as a code for amino acids.
