Chapter 14 - DNA
These are considered the "building blocks" of a DNA molecule
What are Nucleotides?
DNA -> RNA -> Protein
What is the Central Dogma of Molecular Biology?
This system of bacterial gene regulation was first described by Jacob and Monod in 1961
What is an Operon?
This molecule cuts DNA leaving either blunt or sticky ends
What is a Restriction Enzyme?
Cells spend upwards of 90% of their time in this phase
What is Interphase?
These two molecules form the "back bone" of a DNA molecule
What are sugar and phosphate?
What is Transcription?
Lactose metabolism in bacteria is controlled by this
What is the Lac Operon?
This protocol, made possible by Taq polymerase, is the backbone of DNA technologies
During this phase DNA replication occurs
Who are Watson and Crick?
This process results in a polypeptide chain/protein
This molecule turns the Trp Operon off
DNA fragments are separated by size using this procedure
What is Electrophoresis?
In this phase DNA is fully condensed and lined up along an imaginary "plate"
What is Metaphase?
The enzyme capable of "unzipping" DNA is called this
What is Helicase?
This organelle is the site of protein synthesis
What is the Ribosome?
If this portion of DNA is inaccessible to RNA Polymerase Transcription cannot occur
What is the Promoter?
A single DNA molecule that contains DNA from two different species is termed
What is Recombinant DNA?
This "cellular movement" occurs during Telophase
What is Cytokinesis?
The two strands of DNA run 5' to 3' and 3' to 5', this feature is termed what
What is antiparallel?
A set of three nucleotides used to determine the amino acid to be added to a growing protein
What is a codon?
Eukaryotic cells are able to produce multiple proteins from one gene through this process
What is Alternative mRNA Splicing?
This system, based on bacterial immune systems, is the forefront of gene editing technology
What is CRISPR-Cas9?
During this phase sister chromatids are fully condensed but randomly scattered about in the cell
What is Prometaphase?
