The base pairs:

Adenine to Thymine (uracil in RNA)

Guanine to cytosine


Transcription and translation

Transcription and translation

  • Transcription: The code in the DNA is converted to a messenger RNA (mRNA) strand.

  • Takes place in the nucleus.

  • Translation: the process by which the message on the mRNA is converted to a protein: Takes place in the cytoplasm and uses ribosomes and transfer RNA (tRNA).
