DNA Replication, Protein Synthesis, and Mutations

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

RNA is read in sections called:

• Triplets
• Genes
• Codons
• Genes

Transcription is a process that in eukaryotic cells takes place in the:

• Nucleus
• Cytoplasm
• Golgi Apparatus
• Rough E.R.

Translation is a process in eurkaryotic cells takes place in the:

• Cytoplasm
• Nucleus
• Nucleolus
• Golgi Bodies
