  2. Transcription (biology) - Wikipedia

    This also removes the need for an RNA primer to initiate RNA synthesis, as is the case in DNA replication. The non -template (sense) strand of DNA is called the coding strand , because its sequence is the same as the newly created RNA transcript (except for the substitution of uracil for thymine).

    From there, the RNA acts as a template for complementary RNA synthesis. The complementary strand acts as a template for the production of new viral genomes that are packaged and released from the cell ready to infect more host cells. The advantage of this method of replication is that no DNA stage complicates replication.

  4. RNA polymerase - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase

    Using the enzyme helicase, RNAP locally opens the double-stranded DNA so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA, a process called transcription. A transcription factor and its associated transcription mediator complex must be attached to a DNA binding site called a promoter region before ...

    This figure shows DNA synthesis, but RNA synthesis occurs through the same mechanism. The cellular processes of DNA replication and transcription involve DNA and RNA synthesis, respectively. DNA synthesis uses dNTPs as substrates, while RNA synthesis uses rNTPs as substrates. [2] NTPs cannot be converted directly to dNTPs.

  6. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    Eukaryotic Transcription. Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. [1] Gene transcription occurs in both eukaryotic and prokaryotic cells. Unlike prokaryotic RNA polymerase that initiates the transcription of all ...

  7. Abortive initiation - Wikipedia

    en.wikipedia.org/wiki/Abortive_initiation

    Abortive initiation is a normal process of transcription and occurs both in vitro and in vivo. [2] After each nucleotide-addition step in initial transcription, RNA polymerase, stochastically, can proceed on the pathway toward promoter escape (productive initiation) or can release the RNA product and revert to the RNA polymerase-promoter open complex (abortive initiation).
