Week 5
A reversible nucleases producing break in the phosphodiester backbone to release tension and prevent DNA tangling during replication.
What is DNA topoisomerase?
Messenger RNAs, code for proteins
What is mRNAs?
These helper proteins prevent misfolding and aggregation by guiding new polypeptides into their correct 3D shapes, all without becoming part of the final protein.
What are Chaperone Proteins?
This is the first molecule to bind at the P site during the initiation of translation in eukaryotes, carrying the starting amino acid.
What is Met-tRNA?
This specific phase of the eukaryotic cell cycle is the only time during which DNA replication occurs
What is S phase?
This RNA-processing step removes introns and joins exons to produce mature mRNA ready for translation.
What is Pre-mRNA splicing?
The specific subunit of the Cap-Binding Complex that physically binds to the 5’ cap during translation initiation.
What is eIF4E?
These organic molecules contain an amino group, carboxyl group, hydrogen, and variable R group, and are the building blocks of proteins.
What are Amino Acids?
Telomere DNA sequences are recognized by sequence-specific binding proteins that recruit which enzyme that extends chromosome ends to prevent shortening during replication?
What is telomerase?
The prominent sub-nuclear structure where ribosomal RNA is transcribed and the initial stages of ribosome assembly occur.
What is the nucleolus?
These interactions occur when polar side chains are positioned on the outside of a protein, allowing them to interact with surrounding water molecules.
What is hydrogen bonds?
This complex that serves as a molecular "memory," of where an intron was removed during RNA splicing.
What are exon junction complexes?
