This kind of macromolecules makes up the cytoskeleton
What are proteins?
100
This is the process by which the information in DNA is converted into RNA that goes out of the nucleus and into the cytoplasm to function in protein synthesis.
What is transcription?
100
Forms the backbone of organic compounds.
What is carbon?
100
This is the fluid filled space inside of the chloroplast's inner membrane
What is the stroma?
100
These structures allow mRNA to pass from the nucleus into the cytoplasm.
What are nuclear pores?
200
These cytoskeletal elements are rigid hollow rods
What are microtubules?
200
This organelle is covered in ribosomes and is often the site of protein synthesis.
What is rough ER?
200
Carbon can be C12, C13, or C14. All have the same number of electrons and the same chemical properties.
What is an isotope?
200
How many membranes enclose the chloroplast?
Two
200
These rod-like structures of DNA are only visible when a cell is dividing.
What are chroomosomes?
300
These cytoskeletal elements are made up of solid fibers of the protein actin.
What are microfilaments?
300
This organelle receives vesicles from the rough ER and modifies their contents, after which thos contents may be exported from the cell.
What is the Golgi complex?
300
Potassium has a atomic mass of 39 and chloride of 35.5.
Name the molecular mass of KCl.
What is the 74.5
300
These are flat, disk-like sacs inside of the chloroplasts.
What are the thylakoids?
300
These short, hairlike projections are made of microtubules.
What are cilia?
400
In order for your muscles to contract, this protein must interact with microfilaments.
What is myosin?
400
This is the process of using mRNA made in the nucleus to synthesize a protein.
What is translation?
400
A measure of an atom’s attraction for electrons.
What is electronegativity?
400
These are stacks of flat, disk-like sacs inside of the chloroplast.
What are the grana?
400
This structure is found in plants and many prokaryotes, but not in animals.
What is the cell wall?
500
Centrioles, which are important in cell division, are made up of these cytoskeletal elements
What are microtubules?
500
Why must a cell use mRNA to transfer information from the DNA before that information can be used to build a protein?
The DNA is in the nucleus, while the other organelles used to build and modify proteins are in the cytoplasm.
500
The loss of one or more electrons by an atom, ion, or molecule
What is oxidation?
500
These are two types of pigments found in the chloroplast
