In eukaryotic cells, what must occur after transcription before the mRNA can be translated?
What is RNA splicing?
The direction that the template strand is read
What is 3' --> 5'?

What is the coding strand?
Where RNA can be found in a eukaryotic cell
What is the nucleus and the cytoplasm?
The number of hydrogen bonds between A and T

RNA strand hangs freely as it is being transcribed, upon completion the transcription complex falls apart and the RNA is separated from...
What is DNA template?
The name of the strand of DNA that is used to make mRNA
What is the template strand?
pieces of mRNA that do code for the protein. These are spliced together and go to the ribosome
What are exons?
The carbon that is lacking an oxygen in deoxyribose
What is the 2nd carbon?
