WebEukaryotic cells also consist of organelles such as mitochondria, golgi apparatus, endoplasmic reticulum, lysosomes and so on. Eukaryotic transcription. Eukaryotic transcription is inferred as a process in which the eukaryotic cells replicate the data in a strand of DNA and copy the genetic knowledge into a new molecule of RNA. WebDec 24, 2024 · It occurs in three main stages: initiation, elongation, and termination. DNA replication in eukaryotes occurs in three stages: initiation, elongation, and termination, which are aided by several enzymes. Initiation Eukaryotic DNA is bound to proteins known as histones to form structures called nucleosomes. WebJun 8, 2024 · Eukaryotic DNA is bound to proteins known as histones to form structures called nucleosomes.
