| bioformatics, proteomics, genomics | field of study would scientists predict a protein and three-dimensional shape and how DNA mutations would affect protein
function.
🗑
|
||||
| 5 codon sequences | the number of codon sequences it would require to produce the following amino acid sequence: alanine - proline - serine -
isoleucine - stop.
🗑
|
||||
| anticodon | group of bases on trna that is complementary to a specific mrna codon
🗑
|
||||
| what takes place during translation | attatchment of ribosome to mrna, binding of 2 trna molecules per ribosome (NOT PRODUCTION OF MRNA)
🗑

🗑
|
||||
| sequence of events in translation | initiation, elongation, termination
