Understanding how genes are expressed is an essential building block to genetics itself. The expression of genes is understood by the process of central dogma – DNA→RNA→protein. The title of each process entitled transcription (DNA→RNA) and translation (RNA→protein).

Answer the following questions that will require you to understand transcription and translation, and be able to critically think about each.

Transcription and Translation

Where in the cell is transcription occurring?

One strand of DNA is being copied. What is another term for the strand?

One strand is being copied, that means it is one what of a what? (think of two other vocabulary words introduced during this unit)

What are two structural differences between DNA the resulting mRNA?

RNA Splicing

Where in the cell does splicing occur?

Why is it important to remove the introns before proceeding with translation?
