200
the single stranded copy of a DNA strand the exits the nucleus and binds to a ribosome
What is mRNA (messenger RNA)
200
Region of cell where translation occurs
What is the cytoplasm (specifically, the ribosomes)
200
the phase in which DNA is replicated to prepare for cell division
What is interphase?
200
The phase when chromatids align along the cell equator
What is metaphase?
300
a unit located on a chromosome that encodes a specific protein or heritable trait
What is a gene?
300
The region of a gene where transcription of RNA begins
What is the promoter?
300
The molecule that carries an amino acid to match the codon of the mRNA strand
What is tRNA?
300
The cell division phase where chromatid pairs split, pulled to two different sides by centromeres
What is anaphase?
300
The phase in which chromsomes condense and then become chromatids, and the nuclear membrane disappears
What is prophase?

Adenine, cytosine, guanine and thymine are examples of these
What are nucleotide bases of DNA?
400
Holes in which mRNA exits the nucleus
What are nuclear pores?
400
The name of the three bases that signals tRNA to stop make the protein
What is the STOP codon?
400
The assembly of microtubules that is used to move chromosomes to opposite poles/sides of the dividing cell
What is the mitotic spindle?
400
The indention that forms at the cells equator during cell division, cutting the cell into two separation portions
What is cleavage furrow?
500
Adenine, cytosine, guanine, and uracil are examples of these
What are nucleotide bases of RNA
500
Organelle in the cytoplasm where mRNA goes after exiting the nucleus
What are ribosomes?
500
The name of the growing chain that is synthesized during the translation process (eventually forming a protein)
What is polypeptide chain?
500
