Study Notes
Eukaryotic Gene Expression
- The mRNA molecule undergoes several modifications, including 5' capping, splicing, and polyadenylation, before being translated into protein.
Translation
- Ribosomes, composed of a large and small subunit, read the RNA sequence during translation.
- The main role of ribosomes is to catalyze protein synthesis during gene expression.
Transcription
- RNA polymerase, an enzyme, is responsible for synthesizing mRNA from DNA during transcription.
RNA Processing
- RNA processing, including splicing and editing, plays a crucial role in gene expression by modifying the RNA molecule.
Genetic Code
- The genetic code determines the sequence of amino acids in a protein based on the sequence of nucleotides in mRNA.
Gene Expression in Eukaryotes vs. Prokaryotes
- In eukaryotes, gene expression is a more complex process involving RNA processing and splicing, whereas in prokaryotes, transcription and translation occur simultaneously.
Host-Virus Interactions
- The final step in the host-virus interaction process is the lysis of the host cell, resulting in the release of new viral particles.
- During the replication step, the virus uses the host cell's machinery to replicate itself.
- The flu, a viral disease, primarily affects the respiratory system.
- The virus binds to specific receptors on the host cell surface during the adsorption step.
- Respiratory syncytial virus (RSV) primarily affects the respiratory system and can lead to severe complications, especially in children.
- Human immunodeficiency virus (HIV) can cause acquired immune deficiency syndrome (AIDS), a chronic and potentially life-threatening condition.
Virology
- Virology is the field of study that helps us understand the interactions between viruses and host cells, as well as the various diseases they can cause.
Hepatitis
- Hepatitis is a viral infection that primarily affects the liver.
