The fibers that extend from centrosome during mitosis are__________	spindle fibers
In the G_o phase, cells __________	exit from the cell cycle
explain ribonucleic acid (RNA)	a molecule made of linked nucleotides
explain uracil	a nitrogen base used in RNA instead of the base thymine found in DNA
explain transcription	the process of transferring a gene's instructions for making a protein to an RNA molecule
explain translation	the process of reading instructions on an RNA molecule to put together the amino acids that make up a protein
explain gene expression	the entire process by which proteins are made
When does transcription begin?	when RNA polymerase binds the the gene's promoter
RNA polymerase adds complementary _________ nucleotides as it "reads" the gene	RNA
In eukaryotes, transcription takes place where?	In the nucleus
What is primary succession?	The colonization of living organisms into an area that was not previously colonized by any living things
What is secondary succession?	The regeneration of the living community after a major disturbance
What is a pioneer species	Species which colonize previously non-colonized land, usually leading to ecological succession
Where does primary succession take place?	In an area that is originally completely empty of life
where does secondary succession take place?	in an area where life once existed bu has then been destroyed
