DNA Replication
Where DNA replication occurs
the nucleus
This enzyme unzips DNA
Helicase
The first step of the protein synthesis
transcription
where translation occurs
cytoplasm
RNA that carries the message from DNA
mRNA
When DNA replication happens in the cells cycle
S phase
The Enzyme builds the new DNA strand
DNA polymerase
where transcription occurs
nucleus
number of bases in a codon
3
RNA that carries amino acids
tRNA
Why DNA replication is necessary
grow,repair,and replace cells
This Enzyme "glues" DNA fragments together
Ligase
what DNA is used as during transcription
a template
start codon
AUG (met)
RNA that makes up ribosomes
rRNA
correct complementary strand for
TAC GGA TCG ATG GCG ATT
ATG CCT AGC TAC CGC TAA
This Enzyme works in the 5' to 3' direction
DNA polymerase
mRNA made from
TAC GGA TCG ATG GCG ATT
AUG CCU AGC UAC CGC UAA
stop codons
UAA< UAG< UGA
difference between DNA and RNA strands
DNA is double-stranded and RNA is single stranded
The correct model of DNA replication
semi-conservative replication
This enzyme responsible for separating strand at the start
helicase
why DNA must be converted into mRNA
protect DNA and allow protein production outside the nucleus
Amino acid chain from
AUG CCU AGC UAC CGC UAA
You will need a amino acid chart to find this out
Met-Pro-Ser-Tyr-Arg-stop
what a chain of amino acids is called
polypeptide
