MOLECULAR GENETICS REVIEW: PROTEIN SYNTHESIS - TRANSCRIPTION

Protein Synthesis - GENETICS 101

Disparate fields have provided advances in our understanding of the impact of protein-synthesis errors on cellular fitness, disease and evolution. Although organisms show adaptations to minimize the deleterious effects of such errors, erroneous protein synthesis can also be exploited for the organism's benefit.

AP Biology Review Part 3: Genetics & DNA and Protein Synthesis

I mean, replicate the strand of DNA on your desk.
MUTATIONS
Mistakes made during DNA replication or protein synthesis called
mutations
.

Read about mutations on your handout.



Protein synthesis
has two stages:
Transcription
and
Translation
Transcription
is the process of making an
RNA
strand from the DNA.
Translation
is the making of
proteins
from the
RNA
code.
Translate means to change "languages" (from nucleic acids to amino acids)
Transcribe means to make a copy of something from one source to another
Transcription
There are three steps to transcription.
Step 1 - a protein known as
RNA polymerase
attaches to a specific part of the DNA molecule
(the promoter)
.
Step 2 - The
RNA polymerase
unwinds and separates the DNA double helix.
Step 3 -
RNA polymerase matches complimentary bases to
one
of the DNA strands.

The nitrogen base
Uracil
binds to
Adenine
rather than
Thymine.
