Name
5. Below is a list of terms that relate to the central dogma and gene expression. For each term,
label the appropriate molecule/feature on the diagram. If the molecule/feature is not shown,
draw in the molecule/feature on the diagram in the appropriate place and label it. On this sheet,
also indicate 1) What type of molecule the term refers to, 2) what process the molecule most
directly functions in (transcription, RNA processing, translation), 3) where in the cell (nucleus,
cytoplasm, etc) the molecule primarily as appropriate (not all information is requested for all
terms). Make sure you answer any additional questions about each term/feature.
