Which of the following events occurs during transcription?
A: Those segments of the RNA strand that do not actually code for the protein are removed.
B: A molecule of RNA is formed based on the sequence of nucleotides in DNA.
C: The message in mRNA is translated into a protein.
D: A cap is added to the RNA molecule.
E: mRNA binds to a ribosome in the cytoplasm.
The correct answer is option B.
During transcription, a molecule of RNA is formed based on the sequence of nucleotides in DNA. During transcription, RNA nucleotides line up with their complementary DNA partners, transcribing the information in DNA into RNA.
The literal meaning of the word “transcription” is “to summarize or paraphrase” in writing. Here, in Genetics, the term “transcription” means the conversion or summarization of the information of DNA into the smaller version of RNA, which can be used by the cell. So, this process of transcription of the information in DNA into RNA is called genetic transcription.
The process of protein synthesis consists of two stages: transcription and translation.
Transcription takes place in the nucleus. The DNA molecule is used as a template to form an RNA molecule in genetic transcription. The translation decodes the genetic code in mRNA and makes a protein molecule.
Transcription is the first part of the molecular biology in which DNA is transcribed into RNA. It is the transfer of genetic information in DNA to messenger RNA. In this process of transcription, the mRNA strand is formed, which is complementary to a DNA strand.
