| Question | Answer |
|---|---|
| complementary base pairing | either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA |
| DNA helicase | DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. |
| DNA polymerase | The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides |
| recombinant DNA | DNA that has been formed artificially by combining constituents from different organisms. |
| replication | Copying a strand of DNA to replicate it |
| semi-conservative replication | Semi-conservative replication would produce two copies that each contained one of the original strands and one new strand. |
| anti-codon | a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA. |
| codon | a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule. |
| DNA sequence | the nucleotide triplets of DNA and RNA molecules that carry genetic information in living cells |
| elongation | The tRNA transfers an amino acid to the tRNA corresponding to the next codon |
| environmental mutagen | a physical or chemical agent that changes the genetic material |
| genetic disorder | a genetic problem caused by one or more abnormalities in the genome |
| initiation | involves the small subunit of the ribosome binding to the 5' end of mRNA |
| messenger RNA | the form of RNA in which genetic information transcribed from DNA as a sequence of bases is transferred to a ribosome. |
| mutation | the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations |
| termination | Ending the sequence |
| transcription | the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA |
| transfer RNA | RNA consisting of folded molecules that transport amino acids from the cytoplasm of a cell to a ribosome. |
| translation | the process in which cellular ribosomes create proteins |
