Eukaryotic Transcription

Eukaryotic Transcription Transcription is the process by which the information in a strand of DNA is copied into a new molecule of RNA. It is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. It results into a complementary, antiparallel RNA strand called a primary transcript. Transcription in Eukaryotes Transcription occurs in eukaryotes … Read more Eukaryotic Transcription

Central Dogma- Replication, Transcription, Translation

Central Dogma- Replication, Transcription, Translation DNA contains the complete genetic information that defines the structure and function of an organism. Proteins are formed using the genetic code of the DNA. Conversion of DNA encoded information to RNA is essential to form proteins. Thus, within most cells, the genetic information flows from – DNA to RNA to protein. … Read more Central Dogma- Replication, Transcription, Translation

Prokaryotic Transcription- Enzymes, Steps, Significance

Prokaryotic Transcription- Enzymes, Steps, Significance Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). In prokaryotic organisms transcription occurs in three phases known as initiation, elongation and termination. Enzyme(s) Involved RNA is synthesized by a single RNA polymerase enzyme which contains multiple … Read more Prokaryotic Transcription- Enzymes, Steps, Significance

Differences between DNA Replication and Transcription

Differences between DNA Replication and Transcription

Differences between DNA Replication and Transcription DNA replication and transcription are fundamental genetic processes that are essential for cell growth and division.  Both DNA replication and transcription processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in … Read more Differences between DNA Replication and Transcription
