Topic 4
This nucleotide pairs with Cytosine in DNA with three hydrogen bonds
What is Guanine
This mechanism uses ribonucleotide triphosphate to synthesize short RNA primers on lagging strand
What is DNA primase
RNA sequence to be removed pre-mRNA splicing
What are introns
These are groups of three consecutive nucleotides on mRNA that specifies for an amino acid
What are codons
This is a site in bacteria rich in AT pairs and is methylated
What is the replication origin
This protein tightly binds DNA during replication and prevents hairpins
What is single strand DNA binding protein
All protein coding genes use this type of RNA polymerase
What is RNA Polymerase II
This adaptor molecule binds the codon and specific amino acids and is 80 nucleotides in length
What is transfer RNA (tRNA)
What is 10.4
This protein allows for double strand breaks to relieve supercoiled DNA during replication
What is Topoisomerase II
The rRNA genes 5.8s, 18s, and 28S transcribe this
What is RNA polymerase I
This class of proteins assist in correct protein folding
What are molecular chaperones
Centromeres and telomeres are found in this chromatin type
What is Heterochromatin
Two homologues DNA helices that have been paired are held together by their reciprocal exchange if two of the four strands present
What is a Holliday Junction
This protein recognizes TATA box and other DNA sequences near the transcription start point
What is TFIID
mRNA translated at high rates form these
What are polyribosomes
This methylation histone modification represents only 1% of abundance in the genome, makes DNA highly accessible, and opens the chromatin for gene expression
What is H4K4me3
One of three polymerases in eukaryotes that finishes Okazaki fragments during replication
What is Polo
Not all of these RNAs appear to have a function but some serve as scaffolds and are part of cell processes like X chromosome inactivation
What is lncRNA (Long non-coding RNA)
This small subunit of rRNA checks for correct codon and anticodon matches
What is 16sRNA
