What did Hershey and Chase use to label DNA and protein?

Radioactive phosphate and sulfur

Radioactive carbon and nitrogen

What was the key finding of Hershey and Chase's experiment?

Protein is the hereditary material

Lipids are the hereditary material

DNA is organized into nucleosomes. A nucleosome contains eight histone proteins at the core (octamer). DNA is wrapped ~2 times around the octamer. Another protein (H1 Histone) holds the DNA in place around the octamer. You should be able to draw a nucleosome on your IB test. Which of the following best describes the purpose of nucleosomes?

To compact DNA and regulate gene expression

To increase the speed of DNA replication

Match the processes with the correct description and location:

Happens in the Nucleus of Eukaryotes when a new cell needs to be made

Constantly happening in the Nucleus of Eukaryotes

On the leading strand, which way does polymerase move?

Toward the replication fork (helicase)

Away from the replication fork (helicase)

On the lagging strand, which way does polymerase move?

Away from the replication fork (helicase)

Toward the replication fork (helicase)

What is the promoter?

Region of DNA where RNA polymerase binds to initiate transcription

A structure that helps maintain the shape of DNA

A region of DNA that codes for a specific protein

A type of protein involved in DNA replication

What is the terminator sequence?

A specific DNA sequence that signals the end of transcription in prokaryotes.

A sequence that determines the beginning of DNA replication in bacteria.

A specific DNA sequence that signals the start of translation in eukaryotes.

A region of DNA that promotes gene expression in prokaryotes.

How often a gene is transcribed (gene expression) is controlled by transcription factors (proteins). The proteins can either help or prevent RNA polymerase from binding to the promoter. Check all that are true:

Activator transcription factors increase gene expression

Repressor transcription factors decrease gene expression

Activator transcription factors decrease gene expression

Repressor transcription factors increase gene expression

Gene expression is also controlled by chemical groups that determine how tightly packed DNA is in a nucleosome . Check all that are true:

Acetylation makes DNA less tightly packed, and therefore increases gene expression.

Methylation makes DNA more tightly packed, , and therefore decrease gene expression.

Acetylation makes DNA less tightly packed, and therefore decrease gene expression.

Methylation makes DNA more tightly packed, , and therefore increases gene expression.

Match the RNA with the correct description.

Carries amino acids to the ribosome

Forms the ribosome (along with proteins)

Match the following descriptions the correct sites within the ribosome:

The exit site (where the tRNA leaves the ribosome after dropping off its amino acid)

Holds the growing polypeptide chain.

Where the tRNA enters the ribosome and its anticodon binds to the codon on the mRNA.

Telomeres are repetitive sequences of DNA at the end of chromosomes.

Telomeres are proteins that protect the nucleus.

Telomeres are only present in plant cells.

Telomeres are found in the cytoplasm of cells.
