Gene Regulation
100
A granular material visible within the nucleus; consists of DNA tightly coiled around proteins.
What is Chromatin?
100
sequence of DNA that codes for a protein and thus determines a trait.
What is a gene?
100
condition in which an orgaism has an extra set of chromosomes.
What is polyploidy?
100
Series of genes that controls the differentiation of cells & tissues in an embryo.
What is a HOX gene?
200
Protein molecule around which DNA is tightly coiled in chromatin.
What are histones?
200
Enzyme similar to DNA Polymerse that binds to DNA and separates the DNA strands during transcription.
What is messenger RNA?
200
a mutation that"shifts" the reading frame of the genetic message by inserting or deleting a nucleotide.
What is frameshift mutation?
200
Region of chromosomes in an operon to which the repressor binds when the operon is "turned off."
What is an operator?
300
Copying process by which a cell duplicates its DNA.
What is Replication?
300
type of RNA that makes up the major part of ribosomes.
What is ribosomal RNA?
300
Gene mutation involving changes in one or a few nucleotides.
What is point mutation?
300
Process in which cells become specialized in structure an function.
What is differentiation?
400
Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule.
What is DNA Polymerase?
400
a group of 3 bases on a tRNA molecule that are complementary to an mRNA codon.
What is an anticodon?
400
Change in a DNA sequence that effects genetic information.
What is a mutation?
400
a group of genes operation together.
What is an operon?
500
The 3rd phase of mitosis, during which the chromosome pairs separate and move toward opposite poles.
What is Anaphase?
500
Region of DNA that indicates to an enzyme where to bind to make RNA.
What is a Promoter?
500
organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer.
What is an autotroph?
500
group of ecosystems that have the same climate and dominant communities.
What is a biome?
