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.
