Molecular Genetics

2. a type of weak bond found between complementary base pairs
5. the biological process of building proteins based on DNA instructions
9. a base is lost or deleted
10. a type of RNA that transfers the code from DNA in the nucleus to the cytoplasm
11. mutation where a substitution does not change the amino acid
13. the process occurring in the cytoplasm of a cell that builds proteins
15. a long molecule in the shape of a double helix and made up of nucleotides
17. an extra base is added or inserted
22. is the site of translation
23. a sequence of three nucleotide bases that represents the code for one amino acid

1. a type of RNA that reads the codons from the mRNA
3. a single strand of DNA tightly coiled around special proteins
4. mutation where a substitution changes the amino acid
6. mutation where a substitution changes the amino acid to a "stop"
7. one base is substituted for another
8. a small section of DNA that carries the information on how to make one protein
12. the process of copying a strand of DNA
14. the process occurring in the nucleus of a cell that copies the instructions from a part of DNA onto a strand of messenger RNA
16. the type of molecule that makes up DNA and RNA; contains sugar, a phosphate group, and a nitrogenous base
18. a single strand of nucleotides; different types are used to translate instructions from DNA into making proteins
19. the sequence of three nucleotides on tRNA that pairs with the codons on of mRNA
20. mutation where the reading frame changes the amino acid sequence
21. is the site of transcription
