One of the benefits of the double stranded DNA structure is that it lends itself to repair, when structural damage or replication errors occur. Several kinds of chemical change may cause damage to DNA:. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA. ).. DNA unzips to open the codes that need to be make certain proteins.. What organelle makes proteins?. Where are these organelles found?. How does the information from DNA get to those organelles?.
