Which of the following is true regarding the process shown in the image?
The process shown above is known as cloning and involves the production of RNA from protein molecules.
The process shown above is known as replication and involves the production of DNA from RNA.
The process shown above is known as transcription and involves the production of proteins from DNA.
The process shown above is known as translation and involves the production of proteins from RNA.
Which component of the DNA molecule provides instructions for the production of the protein and determines the traits of the organism?
The phosphate group
The sugar molecule
The sequence of nitrogen bases
The hydrogen bonds that hold the sugars to the bases
What is the purpose of the cellular process shown in the image?
Preserving genetic information for future generations
Deleting the information in the sequence produced from the DNA template
