Molecular Genetics

3. Fragment end of DNA that is fully base-paired after having been cleaved by a restriction enzyme.
4. This sequence of DNA binds RNA polymerase to initiate transcription.
7. This scientist discovered the base-pairing rule for DNA.
9. Enzymes that are able to cleave double stranded DNA into fragments.
13. This enzyme removes the introns from the transcripted DNA.
16. This type of RNA is used to make ribosomes.
18. Three bases that serve as a code for amino acids.
19. A cluster of structural genes located on bacterial chromosomes.
20. This is the coding region of DNA in transcription.

1. Replicating strand that is not synthesized continuously.
2. Adenine and thymine belong to this group of nucleotides.
5. A structure level of DNA that involves a 3D shape with major and minor grooves along its length.
6. 5' caps added onto transcripted DNA are made of this.
8. A protein that releases a finished polypeptide from the ribosome after translation is completed.
10. The third and final step of transcription.
11. Coding region of DNA.
12. Enzyme that unwinds the DNA helix by severing H-bonds.
14. In translation, the mRNA start codon enters this site for translation to begin.
15. This type of mutation results from base pairs switching sides; is the cause of sickle cell anemia.
17. Small circular pieces of DNA that can enter and exit bacteria.
