Biology Exam 2

The animal extracellular matrix contains what in comparison to plant ECM?

Desmosomes are a cell-cell attachment mostly commonly found in which of the following animal cells?

Which of the following is NOT part of a desmosome?

Which of the following is NOT a lipid-soluble signaling molecule?

In order for a G protein to be activated, what needs to occur?

Which of the following is NOT a second messenger?

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

Where are the protein components of the extracellular matrix synthesized?

[blank_start]Lipid-soluble[blank_end] signaling molecules often pass through the plasma membrane and bind to cytosolic signal receptors. Signaling molecules that are [blank_start]not lipid soluble[blank_end] often bind to signal receptors in the plasma membrane.

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

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

The use of signal transduction systems enables cells to

Who discovered the secondary structure of DNA?

Which of the following images depicts semiconservative replication?

How many origins of replication do eukaryotic chromosomes have?

What is the primary responsibility of SSBPs?

Which is true of telomerase?

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

Synthesis of the [blank_start]leading strand[blank_end] is continuous, but synthesis of the [blank_start]lagging strand[blank_end] is discontinuous because on that strand, the DNA polymerase moves away from the replication fork.

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

How are Okazaki fragments synthesized?

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

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

mtDNA has the following characteristics

Which of the following is the central dogma of biology?

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

Which of the following is the universal start codon?

What are the three stop codons that signal that the end of translation?

Which of the following is not true about the genetic code?

Which of the following point mutation are most likely to be deleterious?

The two purine bases in the DNA are

A codon would contain

Point mutations that alter the meaning of subsequent codons are called

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

Why do NTPs have a significant amount of potential energy?

Which of the following are part of eukaryotic RNA processing?

What is removed from eukaryotic RNA transcripts?

The secondary structure of tRNA resembles...

Which is the correct sequence of the elongation of translation?

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

Translation initiation occurs when...

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

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?

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

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

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

In [blank_start]eukaryotes[blank_end], transcription and translation of an RNA cannot occur together because transcription occurs in the nucleus and translation occurs in the cytoplasm.

Any technique for picking particular types of mutants out of many randomly generated mutants is known as...

What holds DNA polymerase in place during strand extension?

an exterior protein coat as seen in Hershey and Chase's experiment is known as
