|
DNA |
code for genetic make up |
DNA can be found in the nucleus of eukaryotic cells |
|
|
RNA |
code for proteins |
RNA makes ribosomes. |
|
|
Gene expression |
the process where gene information is used to synthesize a function gene product |
The product of gene expression is usually protein |
|
|
mRNA |
the temporary copy of gene that codes a protein |
mRNA is the messenger RNA |
|
|
tRNA |
RNA that amino acids are attached to |
tRNA is the transfer RNA. |
|
|
Genetic code |
the sequence bases of DNA and RNA |
thyamine
Genetic code makes up DNA |
|
|
Codon |
a triplet in mRNA |
|
|
|
Anticondon |
a triplet in tRNA |
|
|
|
Transcription |
the assembly of RNA molecules |
Transcription is a multistep process. |
|
|
RNA polymerase |
RNA enzyme |
RNA polymerase jons bases of DNA |
|
|
RNA processing |
the breaking down of mRNA |
RNA processing only takes a few minutes |
|
|
Intron |
segments of RNA that don't code for protein |
Introns are apart of RNA processing |
|
|
Exon |
the remaining parts of transcript |
Introns are apart of RNA processing |
|
|
Splicing |
removing introns and rejoining cut ends |
removing introns
Splicing requires precise recognition. |
|
|
tRNA charging |
the splicing of tRNA |
Protein enzymes catalyze tRNA charging. |
|
|
Translation |
the assembly of proteins on ribosomes |
tRNA charging
Translation is a multistep processes. |
|
|
Tertiary structure |
three dimensional structure of a molecule |
Proteins have a tertiary structure. |
|
|
Translation error |
an error occurring during the process of translation |
misreading
Most translation errors are caught and corrected |
|
|
Translational frame shift |
when the sequence of nucleotides are shifted and the frame changes |
codon shift
Frame shifts mutations can result in different sequence of amino acids. |
|
|
Frame shift mutation |
the result of a translation frame shift |
codon shift
Frame shifts mutations can result in different sequence of amino acids. |
