DNA Review
What is the name
for the shape of
DNA?
Where are the
strong bonds?
Where are the
weak bonds?
RNA
Introduction
RNA stands for:
ribo-nucleic acid
RNA is almost like DNA,
but there are 3
differences
Differences between DNA
and RNA
1. Different sugars
(DNA=deoxyribose)
(RNA=ribose)
Differences cont.
2. DNA is double
stranded (2 sides)
RNA is single
stranded (1 side)
3. DNA has “T”
(thymine)
RNA has “U”
(uracil)
Always remember…
RNA

U

Monomers are

Transcription
Where is DNA?
The nucleus
What does DNA
code for?
Proteins
What organelle
makes
proteins?
Ribosomes
(outside of the
nucleus)
Label the DNA and the proteins
in the cell
DNA
Ribosomes:
make proteins
DNA needs to get out of
the nucleus
It needs a messenger
mRNA (messenger RNA): carries
information from DNA to the cytoplasm
Transcription: making
mRNA from DNA
DNA
mRNA
Transcription happens in the
nucleus
RNA Transcription
mRNA pairs up with DNA just like
DNA
C with G
A with U
If the DNA were:
CTCAGT
mRNA would be:
GAGUCA
DNA: G C G T A T C G
mRNA: C G C A U A G C
Transcribe these DNA
Strands into mRNA
strands
• ATCGAA
• GGCATA
• CTAGCG
Translation
Translation
Translation is the process of making
mRNA into a protein.
mRNA
protein
Translation happens in the
ribosome
Translation
Translation needs 2 types of RNA
• rRNA (ribosomal RNA): makes up the
ribosome
• tRNA (transfer RNA): carries amino acids
(the monomer of proteins) to the ribosome
so they can make a protein
