DNA Replication
Does an exact replica come out of DNA replication or no?
Yes, an exact replica is created during DNA replication.
What/who does DNA transcription happen to?
All living organisms
What is the purpose of translation?
To create protein
Can a living organism function if there is a permanent malfunction in their DNA to protein process?
No
How many steps are in replication?
3
How long would it take for you to die if your body didn't transcribe your DNA?
Minutes or hours
What part of the cell assists in DNA translation?
Ribosomes
Where does protein synthesis occur in the cell?
The cytoplasm
What does the m stand for in mRNA? (we learned this in the past)
Messenger
Where does DNA replication take place in each type of cell?
Inside of the nucleus for eukaryotic cells, inside the cytoplasm for prokaryotic cells
Who were the two people to help discover it?
Scientist Francis Crick & Roger D. Kornberg
When does translation occur after?
After transcription
ABOUT how many different types of amino acids are there?
20
Put these in order. (Translation, Transcription, Replication, DNA to Protein)
1. Replication
2. Transcription
3. Translation
4. DNA to Protein
What is the first step of DNA replication?
Initiation
Note: The dna molecule unwinds and “unzips” into a y shape.
What is Thymine replaced with when RNA is created?
Thymine is replaced with a base called Uracil.
What does RNA stand for and why?
RiboNucleic Acid.
It contains Ribose as its sugar instead of Deoxyribose like in DNA.
What are the chains made of that are created during protein synthesis?
Amino Acids
What does the transcription step produce that the replication step doesn't?
RNA
Replication produces DNA.
Why is replication described as semi-conservative?
Each new DNA molecule contains an original old strand.
What uncoils the DNA during transcription?
An RNA polymerase.
Which RNA brings amino acids to the ribosome?
tRNA
3
What year did Marshall Nirenberg do what he did?
1961
