DNA vs RNA Lesson R-T-T> Condon

• ​Semi- conservative replication-

• ​Each DNA molecule is "half old" and "half new"

​1) Replication- DNA copies itself into new cells

​

2)Transcription-(copy) DNA is transcribed into mRNA

​

​3)Translation- mRNA leaves and travels to the ribosome where it is read in groups of 3, called codons.

​

-Each codon codes for one amino acid.

​

​mRNA- carry the DNA's genetic code outside of the cell. The complimentary copy of DNA

​tRNA- Transfers the correct amino acid to the ribosome based on the codon sequence of the mRNA.

rRNA- Makes up the ribosome
