Translation
Transcription
• DNA is unwound to expose the genetic instructions.
Transcription
• The instructions are copied in order to form mRNA.
Translation
• The newly created RNA strand travels through a Nuclear Pore
Complex out of the Nucleus.
Translation
• Outside of the Nucleus, the RNA strand attaches itself to a
Ribosome.
• Here, the language of Nucleic Acids is translated into the
language of Amino Acids (Proteins).
Ribosome
mRNA
Translation
• Inside the Ribosome, a tRNA assembly line builds a chain of Amino Acids, based
specifically on the chain of Nucleic Acids that are attached to the RNA strand.
• The Amino Acids are linked into long chains. Their arrangement determines the type
of protein they will form.
