12 Gene Expression Q1

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?

• The two different cells become mutated
• The proteins expressed in each cell are different
• They actually have different DNA in the two types of cells.
• The genome of the different cells changes

What structure of this molecule binds with the mRNA molecule?

• Amino Acid
• tRNA
• Anticodon
• Codon

what does a promoter do?

• it allows a gene to be transcribed
• it creates a DNA segment
• it is another word for ribosomes
• it is another word for RNA

Which RNA type is the result of transcription?

• tRNA

• Non-coding RNA

• rRNA

• mRNA

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.

Epigenetics modulates genetic expression:

• differently in each cell in the body.

• by altering the genome.

• in response to only intracellular processes.

• consistently throughout an individual's life.

When DNA is transcribed to RNA.... 

• A pairs with U
• C pairs with U
• A pairs with T
• C pairs with T

When the RNA gets to the ribosomes, which molecule transfers to the mRNA to amino acids?

• DNA
• mRNA
• tRNA
• Replicated RNA

What is a Codon?

• 4 base pairs that transfer to amino acids
• 3 base pairs that transfer to amino acids
• 3 base pairs that transfer to DNA
• 3 base pairs that transfer to mRNA

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA

• Met-Pro-Ala-Val
• Met-Pro-Val
• Tyr-Gly-His
• Tyr-Gly-Arg-His
