Codons

Willowridge Transcription Translation codon Chart

Replication how does one cell become two?

Each new cell must have its own set of instructions called DNA. A copy of DNA is made for each cell of your body

DNA Replication

While the DNA is being copied, all the organelles in a cell are also being copied to make a complete new identical cell.

Replication, Transcription, Translation

Replication is when the DNA is being copied

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). 

Translation is when the mRNA code is interpreted and used to create proteins from Amino Acids.

Why do we need protein?

Protein helps us grow and heal
