2 DNA TO RNA Transcription is the process of creating a molecule that can carry the genetic blueprint for a particular protein coding gene from the DNA in the nucleus to the ribosomes found outside the nucleus.

3 RESEARCHERS HAVE CONFIRMED THE EXISTENCE OF 19,599 PROTEIN- CODING GENES IN THE HUMAN GENOME AND IDENTIFIED ANOTHER 2,188 DNA SEGMENTS THAT ARE PREDICTED TO BE PROTEIN-CODING GENES.

4 CHROMOSOMES ARE FOUND IN THE NUCLEUS

5  Chromosomes are made of DNA and Protein.  Genes are a segments of DNA that tells a cell how to make different proteins

6 RIBOSOMES THE ORGANELLE THAT JOINS AMINO ACIDS INTO PROTEINS.

7 GETTING THE PROTEIN INSTRUCTIONS FROM THE DNA TO THE RIBOSOME

8 RNA CAN LEAVE THE NUCLEUS THROUGH NUCLEAR PORES AND TRAVEL TO RIBOSOMES

9 RNA STRUCTURE LIKE DNA…RNA IS MADE OF NUCLEOTIDES

10 RNA THE 4 NITROGEN BASES AND RIBOSE SUGAR

11 BASE PAIRING RULES

12 TRANSLATION HAS 3 STEPS

15 RNA PROCESSING  DNA contains non-coding regions called introns.  These may be viral DNA or genes that are no longer used by the cell.  The coding regions of DNA are called Exons.  RNA processing is a process that removes the introns and joins the exons.  The resulting molecule is called mRNA [messenger RNA]

16 REMOVING INTRONS WITH SPLICEOSOMES
