introduction
| Question | Answer |
|---|---|
| To synthesize a protein, the sequence of bases in a messanger RNA mol is translated into . | a sequence of amino acids in a polypeptide |
| The genetic code specifies the relationship between | the bases of a triplet codon in mRNA and the amino acid it codes for |
| What are the steps that occur in nucleus before RNA is exported to cytoplasm? | Enzyme catalyzed addtion of 5'cap, splicing (intron removal) by spliceosome, enzyme catalyzed addtion of 3' poly(a) tail |
| in bacteria, ribosomes attach to mRNAs and begin synthesizing proteins before | transcription is completert |
| in eukaryotes, RNAs are processed in the nucleus and then mRNA | are exported to the cytoplasm |
