When it is time to replicate, the DNA unzips (at the hydrogen bonds).

Replication. When it is time to replicate, the DNA unzips (at the hydrogen bonds). Replication. New complementary nucleotides move in to match BOTH halves of the DNA and form hydrogen bonds with the old nucleotides. Replication.

Transcription and Translation

Transcription and Translation. From DNA to RNA to protein. Overview. Genes in DNA contain information to make proteins. The cell makes mRNA copies of genes that are needed. The mRNA is read at the ribosomes in the rough ER. Protein is produced. Key Players.

DNA Replication

DNA Replication. Cell DNA is copied. What is meant by DNA REPLICATION:. Replicate means copy, or duplicate. DNA in cells must be copied exactly. During the process of DNA replication, a duplicate of the DNA molecule is made. Not a good copy. Why must DNA be Copied?.
