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.

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.

What structure of this molecule binds with the mRNA molecule?

• Amino Acid
• tRNA
• Anticodon
• Codon

• vestigial structures
• homologous structures
• adaptive radiation
