Question

What is produced during transcription?

Answer 1

Transcription involves the copying of DNA by which the information in a strand is copied into a new molecule of messenger RNA. A DNA sequence is read by an RNA polymerase during the process of transcription which produces an antiparallel RNA strand that is complementary.

Complete answer:
A strand of RNA is produced during the process of transcription from a strand of DNA. The complementary RNA strand which is antiparallel and is produced by a DNA sequence is known as primary transcript. The transcription process takes place in several steps which involve the RNA polymerase which binds together with one or more transcription factors to promoter DNA. A transcription bubble is generated by the RNA polymerase that helps in the separation of two strands of the DNA helix. The separation is done by breaking the hydrogen bonds between complementary DNA nucleotides. The RNA nucleotides that are complementary to the nucleotides of the DNA strand get added to the RNA polymerase.
RNA polymerase forms the RNA sugar-phosphate backbone for the formation of the RNA strand. The synthesis of the new RNA strands takes place by breaking the hydrogen bonds of the RNA - DNA helix. The RNA is for the process if the cell consists of a nucleus and that includes the process with splicing, polyadenylation and capping. The nuclear pore complex is the exit point for the remaining RNA in the nucleus.

Note:
The mistake in the process of transcription can cause mutations during transcription which make improper proteins and if the mutation takes place in the gametes then the offspring will have a positively negatively or neutrally effective DNA.
