After parts of the RNA are removed these remaining parts are joined together to make mRNA.
What are exons?
200
These separate during Anaphase 1
What are homologous chromosomes?
300
Anything that speeds of a chemical reaction.
What is a catalyst?
300
This fossil transitional species between dinosaurs and birds had feathers, claws on is wings, a long bony tail and teeth.
What is archaeopteryx?
300
The engineered combination of the desired gene, a promoter sequence, a termination sequence, and a marker gene.
What is a gene cassette?
300
This type of RNA carries amino acids to the ribosome.
What are Transfer or T-RNAs?
300
These 3 processes generate tremendous genetic diversity.
What are crossing-over, independent assortment of homologous chromosomes, sexual reproduction.
400
When a molecule other than the normal substrate is bound to the active site and slows or prevents the normal reaction.
What is competitive inhibition?
400
This is an ancestral trait not normally observed that randomly appears on an organism.
What is an atavism?
400
The process that the terminator sequence stops?
What is transcription?
400
This is the sequence of ribonucleotides that translates to a specific amino acid.
What is a codon?
400
Crossing over occurs during this phase.
What is prophase 1?
500
Protein catalysts that controls the metabolic reactions of an organism.
What are enzymes?
500
