DNA, RNA, & Genetics

In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in the cell nucleus, is called

• translation
• mutation
• DNA replication
• transcription

Translation is crucial to the process of making proteins. Which statement best describes what takes place during translation? 

• A copy of chromosomal DNA is created 
• Information in mRNA is converted into a sequence of amino acids in a protein 
• A RNA copy of a DNA strand is made.
  
• Instructions from DNA in the nucleus are brought to the cytoplasm
