Eukaryotic Chromosomes and Ploidy

Transcription is the process that __________.

• uses the information in a gene to make a molecule of mRNA

• uses the information in a gene to make a protein

• uses the information in a molecule of mRNA to make a protein

• uses the information in a protein to make a gene

What is a gene?

• a molecule of DNA

• A sequence of DNA

• A sequence of mRNA

• A sequence of amino acids

Which part of a tRNA molecule does the ribosome remove?

• anticodon

• amino acid

• protein

• codon

What is the relationship between mRNA and protein?

• mRNA turns into the protein

• mRNA is the building block of proteins

• mRNA is used to order the amino acids in a protein

• mRNA makes the amino acids

The endomembrane system is a series of membrane bound organelles that help get certain proteins to their final destination. What cells have an endomembrane system? Check all that apply.

• plant cells

• animal cells

• bacterial cells

• fungi cells

Where are ribosomes found in eukaryotic cells?

• cytosol and rough ER

• cytosol and golgi apparatus

• cytosol and nucleus

• rough ER and nucleus

What types of proteins would be made by ribosomes in the cytosol?

• ones that are targeted to the nucleus

• ones that are targeted to the plasma membrane

• ones that are targeted to the extracellular environment

What type of proteins are made by ribosomes embedded in the rough ER

• Those targeted to the cytosol

• those targeted to the mitochondria

• those targeted to the nucleus

• those targeted to the extracellular environment

What happens in the golgi apparatus?

• proteins are made

• amino acids are made

• proteins are modified

• carbohydrates are modified

What is the order in which proteins travel through the endomembrane system?

• rough ER -> golgi -> plasma membrane

• rough ER -> plasma membrane -> golgi

• golgi -> rough ER -> plasma membrane

• plasma membrane -> golgi -> rough ER
