The phase of the cell cycle during which cells divide is known as this. AND When cells are not dividing, they are in this phase.
What is MITOSIS? What is INTERPHASE or g0
Name one example of positive Gene regulation and one example of negative Gene regulation.
Positive:
Enhancers
Activators
Splicing/Alternative RNA splicing
Histone Acetylation
Protein Processing
Negative:
Histone Deacetylation
Repressors/Silencers
DNA Methylation
RNA Degradation
RNA interference by microRNAs
Regulatory Proteins
Proteasomes
This is a piece of circular bacterial DNA.
What is a PLASMID?
The shape of DNA, first published by Watson & Crick, is described as this. AND What is the name of the scientist whose data Watson & Crick used without permission to form their hypothesis:
What is a double helix? Who is Rosalind Franklin?
DNA is a polymer made up of monomers called __________.
What are nucleotides.
These are the two steps of protein synthesis. AND Where does each step occur in prokaryotes and eukaryotes?
What are TRANSCRIPTION and TRANSLATION? AND Prokaryotes- both in cytoplasm Eukaryotes- Transcription in nucleus; translation in cytoplasm
The removal of this type of molecule allows chromatin to unwind in eukaryotic DNA so that transcription occurs.
What is a METHYL GROUP or Histones/histone acetylation
Explain how gel electrophoresis aids in DNA fingerprinting.
It separates DNA restriction fragments by size. Smaller fragments travel farther in the gel.
This sugar is part of the backbone of the DNA molecule.
What is deoxyribose?
Chromatin is wound around this protein when DNA is in its highly condensed form, this makes Gene expression difficult.
What is a HISTONE?
The 3 ways that bacterial/prokaryotic genomes change, other than by mutation are:
Conjugation
Transformation
Transduction
Adenine and ___________ are both purines, while cytosine and ___________ are both pyrimidines.
What are GUANINE and THYMINE?
These two types of regulatory proteins are responsible for regulating cell division/cell cycle checkpoints. AND When cells are destroyed, they go through this process.
What are CYCLIN and CDKs?
What is APOPTOSIS?
Sequences of genes that are removed from mRNA during splicing/RNA processing before translation are called ____________.
What are INTRONS?
The enzyme that recognizes and cuts specific RNA sequences in the _________ system is called Cas9.
What is CRISPR?
