Week 5
Enzyme that seals the remaining nicks between DNA fragments during replication, joining the fragments into a continuous strand.
What is DNA ligase?
Another name for the transcribed template DNA strand.
What is the antisense strand?
Location where ribosomes are found in prokaryotic cells.
What is cytoplasm?
This enzyme is responsible for phosphorylation.
What is kinase?
This enzyme breaks phosphodiester bonds to release the tension of the DNA strand during replication.
RNA protein complex that removes introns from pre-mRNA and joins the exons together.
What is the spliceosome?
Primary start codon in mRNA that signals protein translation.
What is AUG?
Theory that explains how mitochondria and chloroplasts evolved from bacteria engulfed by ancestral cells.
What is the endosymbiotic theory?
One of these cell types is reproductive cells that pass genetic info to offspring. The other cell type makes up all other cells that get differentiated into various bodily structures.
What are germ cells vs somatic cells?
This transcription factor binds to the RNA polymerase and the promoter DNA during bacterial transcription, positioning the polymerase for transcription initiation.
What is sigma (σ) factor?
This enzyme attaches the correct amino acid to its corresponding tRNA during protein synthesis.
What is aminoacyl-tRNA synthetase?
This quantifies the amount of disorder in the universe following a reaction, also known as free-energy change.
What is delta G?
In this important intermediate structure formed during homologous recombination, two homologous DNA helices are held together by the reciprocal exchange of DNA strands.
What is a Holliday Junction?
Which transcription factor positions the polymerase at the transcription start site.
What is TFIIB?
This RNA molecule has a cloverleaf-shaped secondary structure.
What is tRNA?
Changes in gene expression when location on chromosome moved to a new region.
What is position effect?
This is somewhat relieved when DNA supercoils.
What is torsional stress?
To form base pairs on the branch-point sequence on the mRNA.
The U2 snRNP displaces the Branch-Point Binding protein for what purpose?
This position in the tRNA anticodon can pair flexibly with nucleotide in mRNA codon.
What is wobble position?
This biomolecular condensate is a distinct, but non membrane bound region of the nucleus where ribosomal RNA synthesis and processing occurs.
What is the nucleolus?
