What are AMINO ACIDS?
200
Holds the sister chromatids together and attaches to the spindle fibers.
What is a centromere?

Cytosine (C) & Thymine (T) are what type of bases?
pyramidines?
300
DNA Polymerase (what does it do?)
What is the enzyme that joins individual DNA nucleotides to make a new strand of DNA (which is a polymer)?
300
The "magic number" that causes cells to divide.
What is Surface Area to Volume Ratio?
300
Delivers specific amino acids to the ribosome for protein construction.
What is transfer RNA (tRNA)?
300
Cell increases in size, replicates its chromosomes and prepares for cell division.
What is Interphase?
400
Codon
What is the 3 base sequence on DNA that codes for one amino acid?
400
CUAAUGU is the mRNA complement of this sequence of DNA.
What is GATTACA?
400
This structure causes the dividing cell to pinch off it's cytoplasm into 2 cells.
What is cleavage furrow (in animals)? What is cell plate (in plants)?
400
An error in the DNA or RNA sequence
What is a mutation?
400
What creates spindle fibres in animal cells?

A section of DNA coding for a particular protein
What is a gene?
500
What experiment proved the semi-conservative nature of DNA replication?
Messelson and Stahl
500
What is HYPTERTONIC?
where there is a higher solute concentration than the other side of the cell membrane.
500
UAG is a stop codon what is the anti codon on the tRNA that match this codon?
There is none! it is a stop codon so there is no Amino Acid involved
