Epigenetics
In many cancers, this epigenetic process occurs adjacent to a p53 or similar gene.
What is methylation?
Caused by water, deamination and depurination are examples of this type of DNA damage.
What is hydrolytic damage?
This broader classification of species tends to be haploid; they also lack membrane-bound organelles.
What are prokaryotes?
What is semiconservative replication?
Deamination converts this nitrogenous base into uracil.
What is cytosine?
This enzyme is in charge of removing acetyl groups from histones, thereby limiting gene expression.
The mechanism by which thymine dimers are repaired; maybe don't forget your sunscreen next time.
What is photoreactivation?
What are kinetochores?
DNA polymerase facilitates the attachment of a new nucleotide — specifically at a phosphate group — to this chemical group on the 3' carbon of the existing strand.
What is a hydroxyl group?
The set of species in which rolling circle replication happens.
What are bacteriophages?
Examples of this process include transduction and conjugation.
What is horizontal gene transfer?
DNA polymerase also proofreads newly synthesized DNA strands; this component of the enzyme is involved in cutting out incorrect bases.
What is exonuclease?
Methylation tends to happen at these two amino acid residues on the histone structure.
What are lysine and arginine?
What is pyrophosphate?
Damage from 8-oxoguanine primarily leads to this type of DNA repair.
What is base-excision repair?
When a nucleosome is removed from chromatin to enhance transcription at a certain promoter site, the chromatin remodeling complex binds to this protein bound to the DNA.
What is the activator?
What is homologous end-joining?
The transcript from this gene surrounds inactivated X chromosomes, as seen under FISH.
What is the Xist gene?
What is DNA primase?
The viral structure in which viral DNA or RNA is delivered to the host cell.
What is a nucleocaspid?
In mice, methylation of this gene leads to yellow fur and obesity.
What is the Augouti gene?
These structures provided templates for new DNA synthesis before primers were used; they are now found in the telomere region.
What are t-loops?
The centromeric region of the chromosome is home to this satellite region.
What is alpha satellite?
This enzyme controls the methylation the GATC sequences at the origin of replication in E. coli, allowing replication to initiate after a short break.
What is dam methylase?
What are Balbiani rings (or puffs)?
