Intro to gene expression (central dogma) - Khan Academy
This process involves two major steps: transcription and translation. In transcription , the DNA sequence of a gene is copied to make an RNA molecule. This step is called transcription because it involves rewriting, or transcribing, the DNA sequence in a similar RNA "alphabet."

Retroviruses, like HIV, have a unique replication process combining lytic and lysogenic elements. They enter cells through direct fusion and use reverse transcriptase to create complementary DNA (cDNA) from their RNA. Integrase integrates viral DNA into …
