RNA substitutes uracil for which nucleotide?

• Adenine

• Cytosine

• Guanine

• Thymine

Translation is a process where:

• a polypeptide sequence is produced from a sequence of rRNA codons.

• a polypeptide sequence is produced from a sequence of tRNA codons.

• a polypeptide sequence is produced from a sequence of mRNA codons.

• a DNA nucleotide sequence is used to produce mRNA codon sequence.

Gene regulation occurs:

• only in some cells.

• when the variability within the genetic code is insufficiently adaptive for the individual to survive in its environment.

• constantly, in all known life forms.

• during embryonic development.

_______ is to transcription as ________ is to translation.

• mRNA / Amino Acid Chain
• Amino Acid Chain / mRNA
• Ribosome / Nucleus
• mRNA / tRNA

Which of these processes begin with an mRNA molecule?

• DNA Replication
• Transcription
• Translation
• None of them

Translation in eukaryotes occurs:

• outside of the nucleus.

• inside of the nucleus.
