A special note that the section you have just covered, Transcription and Translation, will be a part of an upcoming quiz.
RNA translation, and protein synthesis
Transcription is the first step in protein synthesis. It is the process of forming a short strand of mRNA from one gene on a long DNA strand.
This mRNA strand can now leave the nucleus and head over to the ribosomes.
It's time to create a protein:
mRNA fact #1:
There are only
bases/nucleotides in RNA:
A, U, G, C
Protein Synthesis: Transcription & Translation
Now that you have spent some time on the two main processes of Protein Synthesis, Transcription and Translation, test your learning below to practice for the upcoming quiz.
DNA is the reason why a seedling can grow into a tree...
...and why a human can have blue eyes.

WHAT is DNA?
In order to do all of this properly though, DNA goes through three processes...
DNA contains the code for making lots and lots of different proteins.

Ribosomes are made of
parts or subunits:
The large and small subunit
these ribosomes are "translators" -> they
Think of ribosomes as translators who make an English speaker understand Chinese!
Why Does DNA have to replicate?
Mitosis is how cells make new cells
Because all cells come from pre-existing cells the DNA must
for cells to divide.
Transcription - STEP 1:
The DNA is unzipped by RNA polymerase
How is this different from DNA replication?
RNA is a
pairs with Adenine
(A + U)
instead of Thymine
(A + T)

Step 3: TERMINATION
Translation of mRNA stops when a STOP codon is reached.
Stop codons do not carry an amino acid
U A A
U G A
U A G
are the 3 stop codons
SUMMARY of Transcription and Translation:
take the mRNA message and turn it into proteins
Without this all the information that DNA has could never be used

foundation of life

New unit: GENETICS
Need to know how DNA works to know how genetics work
Questions we will try to answer:
What is life?
What are inherited or genetic diseases
Why do I look the way I do?
How does my body grow?
Overview: Transcription and Translation
Transciption and Translation Summary
Messenger RNA transcribes the message from the DNA
What are some proteins that the body makes?
Before the mRNA can leave the nucleus it needs to be PROCESSED
Introns -- get cut out (stay IN the nucleus)
Exons -- EXIT the nucleus as part of finalized mRNA
