DNA Structure
In eukaryotic cells, most of the DNA is found in this location.
What is the nucleus?
The enzyme that synthesizes a new strand of DNA.
What is DNA polymerase?
This molecule is used as a template to make RNA in the process of transcription.
What is DNA?
This molecule is used as a template to make proteins in the process of translation.
What is mRNA?
A group of gene in prokaryotic cells under the control of one regulator element.
What is an operon?
What are histones?
A laboratory technique used to replicate DNA for use in forensic analyses.
What is PCR?
This is the location of a prokaryotic cell where transcription occurs.
What is the cytoplasm?
This type of RNA is considered the "translator" of gene expression by binding to mRNA and carrying in corresponding amino acids.
What is tRNA?
In an operon, this binds to the operator to turn off gene expression.
What is a repressor?
These components make up a nucleotide.
What are a sugar, phosphate, and base?
These two bases, A and G, are paired with these complementary bases.
What are T and C?
This is the location in a eukaryotic cell where transcription occurs.
What is the nucleus?
This type of RNA is a major component of the ribosome.
What is rRNA?
This is the major advantage to regulating gene expression.
What is the conserving of resources (especially energy)?
This type of bonds holds the two strands of DNA together.
What is a hydrogen bond?
This enzyme unwinds and separates the two DNA strands in preparation of DNA replication.
What is helicase?
This enzyme synthesizes RNAs using complementary base pairs to DNA.
What is RNA polymerase?
A macromolecule made up of repeating subunits called amino acids.
What is a protein?
This level of gene expression regulation in eukaryotes is the most important level.
What is transcription initiation?
These two scientists discovered the structure of DNA by building a model of it.
Who are James Watson and Francis Crick?
These segments of our chromosomes vary in length from person to person and can be used for DNA fingerprinting.
What are STRs (short tandem repeats)?
This is the mRNA strand made from the following DNA template: TAG GCT
What is ATC CGA?
These are the two sites in eukaryotic cells where ribosomes are located and protein synthesis occurs.
What are the cytoplasm and the rough endoplasmic reticulum?
This is the reason for and the advantage of having so many levels of gene expression regulation in eukaryotic cells.
What is highly regulating levels of specific proteins?
