15. Gene Expression

Which of the following is the best definition of a gene?

The strand of DNA that has the same sequence as the RNA molecule being created during transcription is the:

Transcription is sometimes described as a process in which RNA is "copied" from the template strand of DNA. This statement is potentially misleading since _____.

What does a bacterial RNA polymerase produce when it transcribes a protein-coding gene?

a. rRNA

b. tRNA

c. mRNA

d. snRNA

Transcription ________.

a. Synthesizes new daughter DNA molecules from an existing DNA molecule

b. Results in the synthesis of an RNA copy of a gene

c. Pairs thymines (T) with adenines (A)

d. Occurs on ribosomes

DNA's primary structure is made up of just four different bases, and its secondary structure is regular and highly stable. How can a molecule with these characteristics hold the information required to build and maintain a cell?

During the process of transcription, ________.

a. DNA serves as a template for the synthesis of more DNA.

b. DNA serves as a template for the synthesis of RNA.

c. DNA serves as a template for the synthesis of proteins.

d. RNA serves as a template for the synthesis of proteins.
