Slide 41 of 20 8-1 Energy and Life Copyright Pearson Prentice Hall -Translating the code -Step 1: DNA unzips. RNA strand is produced. Uracil pairs with Adenine -Step 2: mRNA leaves nucleus, attaches to ribosome, provides code, ribosome moves along mRNA. -Step 3: Molecules of tRNA attach to mRNA, tRNA reads by pairing 3 letter codes. -Step 4: protein grows longer, until a stop sign.
