Topic 4
The Material of which chromosome are made of.
What is Chromatin?
Transmit genetic information from parents to offspring
What is Germ Cells?
The 5' cap of mRNA and this other part of mRNA are not encoded by DNA.
What is the 3' poly-A tail?
Machinery that catalyzes protein synthesis.
What are ribosomes?
Highly condensed region that makes up 40% of the genome.
What is Heterochromatin?
"Y" shaped region of the DNA replication where new daughter cells are formed.
What is a Replication Fork?
This feature of ribose allows for the removal of introns during RNA splicing
What is a -OH group on the 2' Carbon?
A consecutive sequence of three nucleotides in mRNA.
What is a codon?
It changes the path of the DNA as it exits the nucleosomes aiding in chromatin packaging.
What is H1 linker histone?
A permanent change in DNA that could destroy an organism if it occurs in a vital position.
What is a mutation?
This nuclear biomolecular condensate structure contains all of the components necessary for ribosome synthesis.
What is the nucleolus?
The amino acid that charges transfer RNA.
What is methionine?
The set of modifications present on histones can strongly affect the expression of the genes encoded in that region of a chromosome.
What is a histone code?
The main source of energy for the mechanical work preformed by DNA helicase during replication.
What is ATP hydrolysis?
What is TFIID?
The elongation factor that is equivalent to prokaryotic ETFU.
What is EF1?
What is Purifying Selection?
they have directly repeated long terminal repeats at their two ends when they are integrated into the chromosomal DNA.
What are retroviral-like retrotransposons?
This happens in response to superhelical tension when the DNA double helix opening is hindered ahead of the RNA polymerase.
What is positive supercoiling?
The initiation factor that leads to the circularization of mRNA by binding EIF4E to poly-A binding proteins.
What is EIF4G?
