During elongation, which site in the ribosome represents the location where the codon is being read?

a. P site

b. E site

c. A site

d. small ribosomal subunit

Which of the following processes correctly describes alternative RNA splicing?

A) It increases the rate of transcription.

B) It can allow the production of proteins of different sizes and functions from a single mRNA.

C) It is a mechanism for increasing the rate of translation.

D) It can allow the production of similar proteins from different RNAs.

What is the function of the release factor during translation in eukaryotes?

A) It binds to the stop codon in the A site in place of a tRNA.

B) It supplies a source of energy for the termination of translation.

C) It releases the amino acid from its tRNA to allow the amino acid to form a peptide bond.

D) It releases the ribosome from the ER to allow polypeptides into the cytosol.

In eukaryotic cells transcription occurs in the nucleus, and translation occurs in the cytoplasm. True or false?

Transcription in prokaryotic cells is terminated at a stop codon. True or false.

Which one of the following statements about RNA processing is true?

A. RNA splicing can be catalyzed by tRNA,

B. Introns are cut out before mRNA leaves the nucleus,

C. RNA polymerase removes exons from the pre-mRNA,

D. A pre-mRNA is often much shorter than the final mRNA molecule, that leaves the nucleus.

Solvolysis of 2-bromo-2-methylbutane in acetic acid containing potassium acetate gave three products. Identify them.

Solvolysis of 2-bromo-2-methylbutane in acetic acid containing sodium acetate gives three organic products. What are they?

What is an example of an acute disease?

If the DNA fingerprint of a suspect does not match a blood sample from a crime scene, what can you conclude?

a. The blood may be from the suspect because DNA fingerprinting has a large error rate.

b. The blood sample had to come from another person, but the suspect may still have been there.

c. The suspect was never at the crime scene.

d. The DNA in the blood sample probably degraded in a short period of time.

Why are active transport systems important to cells?

In the Krebs cycle, what molecule acquires most of the energy that is released by the oxidation of acetyl CoA, and how many of these molecules are produced during each turn of the cycle?
