Exam 5 review

The process in which DNA gets made into RNA is called...

• Replication

• Translation

• Transcription

• Transfer

Which RNA type is the result of transcription?

• tRNA

• Non-coding RNA

• rRNA

• mRNA

In order for a gene to be expressed, ___ must bind to the gene's ___, a specific sequence of nucleotides at one end of the gene, thus initiating transcription.

• DNA polymerase, promotor

• DNA polymerase, operator

• RNA polymerase, promotor

• RNA polymerase, operator

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.

What structure of this molecule binds with the mRNA molecule?

• Amino Acid
• tRNA
• Anticodon
• Codon

Which of these processes begin with an mRNA molecule?

• DNA Replication
• Transcription
• Translation
• None of them

Monozygotic twins can look different to one another because:

• they have different genetic material from the mother but the same genetic material from the father.

• they have different genetic material from the father but the same genetic material from the mother.

• the environment is determinative of phenotype.

• a mutation has occurred in one twin during embryonic development.

In eukaryotic cells, after transcription, the mRNA

• exits the nucleus unchanged.

• is processed before leaving the nucleus.

• enters the nucleus.

• is replicated before leaving the nucleus.

Which of the following statements regarding mRNA is correct?

• Exons are included in the protein sequence, while introns are left out
• Introns are included in the protein sequence, while exons are left out
• Exons and Introns can both be included or left out depending on the protein
• Exons and Introns are both part of the mRNA sequence, but only exons are part of the rRNA and tRNA
