200
A type of RNA that brings amino acids to the ribosome for protein synthesis
What is tRNA (transfer RNA)
200
In this phase, chromosomes line up in the middle of the cell.
What is metaphase?

The packages that ship materials throughout the cell
What are vesicles?
300
The name given to DNA that has been compacted (condensed) is known as this.
What is a chromosome?
300
A type of RNA that goes to ribosomes to make proteins. These are the instructions.
What is mRNA (messenger RNA)
300
These structures act as an anchor for the microtubules (mitotic spindles) that pull apart the chromosomes.
What are centrioles?
300
This critical event in meiosis occurs during prophase I and does not occur meiosis.

1) At the BEGINNING of meiosis, cells have TWO copies of each chromosome. They are known as:
2) At the END of meiosis, cells have ONE copy of each chromosome. They are known as:
