Which of the following statements about codons in prokaryotic cells and eukaryotic cells is correct?
A.
Prokaryotic codons are longer than eukaryotic codons.
B.
Eukaryotic codons are made of DNA, and prokaryotic codons are made of RNA.
C.
Prokaryotes do not have mRNA, so there are no codons.
D.
Codons are very similar, no matter whether the cell is prokaryotic or eukaryotic.
Which of the following statements are NOT true?
A. Replication is the process of making DNA and takes place in the nucleus of prokaryotic cells.
B. Translation produces a polypeptide that may require additional processing to become a functional protein
C. Transcription starts at the promoter of eukaryotic cells and scans until reaches the start codon.
D. Splicing results in exons being put together and introns being removed
