1

Which of the following demonstrates the mechanics of G-Protein-Coupled Receptors

1

Where are the protein components of the extracellular matrix synthesized?

1

( Lipid-soluble, Non-lipid soluble, Hydrophobic ) signaling molecules often pass through the plasma membrane and bind to cytosolic signal receptors. Signaling molecules that are ( non-lipid soluble, lipid soluble, hydrophilic ) often bind to signal receptors in the plasma membrane.

1

One unique feature of lipid soluble signaling molecules are their ability to

1

The connecting of cytoskeletons between adjacent cells in animal tissues is accomplished using

1

The use of signal transduction systems enables cells to

How many origins of replication do eukaryotic chromosomes have?

1

What is the primary responsibility of SSBPs?

1

Which is true of telomerase?

1

Which of the following types of repair occurs after DNA synthesis is complete?

1

Synthesis of the ( leading strand, lagging strand ) is continuous, but synthesis of the ( lagging strand, leading strand ) is discontinuous because on that strand, the DNA polymerase moves away from the replication fork.

1

Which of the following is NOT a property of DNA polymerase?

1

How are Okazaki fragments synthesized?

1

The enzyme involved in adding new nucleotides to the leading and lagging strands of DNA during replication could be

1

Multiple RNA primers and fragments of DNA during DNA replication would be characteristic of

1

mtDNA has the following characteristics

1

Which of the following is the central dogma of biology?

1

Which of the following is NOT an example of a genotype?

1

Which of the following is the universal start codon?

1

1

The two purine bases in the DNA are

1

A codon would contain

1

Point mutations that alter the meaning of subsequent codons are called

1

What must bind to bacterial RNA polymerase before transcription can begin?

1

Why do NTPs have a significant amount of potential energy?

1

Which of the following are part of eukaryotic RNA processing?

1

What is removed from eukaryotic RNA transcripts?

1

The secondary structure of tRNA resembles...

1

Which is the correct sequence of the elongation of translation?

1

Which of the following does NOT take place in the nucleus of a eukaryotic cell?

1

Translation initiation occurs when...

1

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

1

Temperature-sensitive conditional mutations cause expression of a wild-type phenotype at one growth temperature and a mutant phenotype at another -typically higher- temperature. Imagine that when a bacterial cell carrying such a mutation is shifted from low to high growth temperatures, RNA polymerases in the process of elongation complete transcription normally, but no new transcripts can be started. The mutation in this strain most likely effects which feature?

1

Which enzymes link the correct amino acid to the correct tRNA?

1

The information used in translation to a peptide, specifying which codon codes for which amino acid is carried by

1

Destruction of an mRNA in the cytoplasm prior to reaching a ribosome would be considered a

1

In ( eukaryotes, prokaryotes, bacteria ), transcription and translation of an RNA cannot occur together because transcription occurs in the nucleus and translation occurs in the cytoplasm.
