Transcript of DNA Replication, Transcription, Translation. DNA Replication The weak hydrogen bonds that hold the...
DNA ReplicationThe weak hydrogen bonds that hold the nitrogen bases break apart by an enzyme
The divided strands are then replicated by their matching nitrogen bases
Your new DNA Strand is then one ‘old strand’ known as the parent strand and one ‘new strand’
Speed of Replication DNA is replicated REALLY FAST
Human cell copies its 6 billion bases & divide into daughter cells in only few hours
Remarkably accurateonly ~1 error per 100 million bases
~30 errors per cell cycle
Errors & FixingDifferent types of errors can happen in
DNAEx: Deletion of nitrogen base or an
insertions of nitrogen base Proofreading enzymes correct any
mistakes that occur during replication.DNA studies have helped us solve
major problems in history and in health.
DNA vs. RNADifference #1:DNA double strand RNA single strand
Difference #2:DNA nitrogen bases: A, G, C, TRNA nitrogen bases: A, G, C, U (Uracil)
DNA Transcription RNA strand is made by reading
one of the DNA strandsIMPORTANT!!! When there is an Adenine base (A), it binds with Uracil (U) in RNA instead of Thymine (T)

nucleus to the ribosomeCODON: three nitrogen basesOne Codon(in order on the RNA
strand) makes ONE amino acidAmino acids put together make a
