Process which leads to the synthesis of RNA is calleda)Terminationb)Replicationc)Transcriptiond)TranslationCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

DNA TO DNA - replication
DNA TO RNA-transcription
RNA TO PROTEIN-translation

Answer

Nothing

Answer

DNA has 2 strands in which one is template strand and another one is coding strand . The template strand is responsible for the manufacturer of RNA molecule which is known as transcription.
it involve 3 steps for transcription which are-
initiation
elongation
termination

Answer

The correct answer is option C
RNA synthesis, or transcription, is the process of transcribing DNA nucleotide sequence information into RNA sequence information. RNA synthesis is catalyzed by a large enzyme called RNA polymerase.

Answer

The correct answer is option 'C' - Transcription. Transcription is the process by which RNA is synthesized from a DNA template. This process is essential for gene expression and protein synthesis.

Here is a detailed explanation of the process of transcription:

1. Initiation: Transcription begins with the binding of RNA polymerase enzyme to a specific region on the DNA called the promoter. The promoter sequence marks the starting point for transcription and helps in the positioning of RNA polymerase.

2. RNA synthesis: Once RNA polymerase is bound to the promoter, it unwinds the DNA double helix and starts synthesizing a complementary RNA molecule using one of the DNA strands as a template. The RNA polymerase adds nucleotides to the growing RNA strand in a sequence that is complementary to the template DNA strand. The RNA molecule is synthesized in the 5' to 3' direction.

3. Elongation: As the RNA polymerase moves along the DNA template, it continues to unwind the DNA helix ahead and synthesize the RNA molecule. The RNA molecule grows longer with the addition of nucleotides.

4. Termination: Transcription terminates when the RNA polymerase reaches a specific termination sequence on the DNA template. This signals the end of transcription, and the RNA polymerase and newly synthesized RNA molecule are released from the DNA template.

5. Post-transcriptional modifications: After transcription, the newly synthesized RNA molecule, called primary RNA or pre-mRNA, undergoes various modifications before it is ready to be used for protein synthesis. These modifications include the addition of a 5' cap and a poly-A tail, as well as the removal of non-coding regions called introns through a process called splicing.

Overall, transcription is a crucial step in gene expression, as it allows the information encoded in DNA to be transcribed into RNA, which can then be translated into proteins.
