Question

Which is the What is the role of RNA polymerase? It creates the DNA strand. It bonds the DNA strand. It helps transcribe the DNA strand. It translates the DNA strand.purpose of transfer RNA? to code for protein synthesis to carry the synthesized genetic information from the nucleus to the ribosomes to synthesize proteins from RNA to bring amino acids to the ribosomes to be assembled into proteins

Answer 1

The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. If the gene encodes a protein, the transcription produces messenger RNA (mRNA); the mRNA, in turn, serves as a template for the protein's synthesis through translation.

Answer 2

The role of RNA polymerase is that it helps transcribe the DNA strand. The purpose of the transfer-RNA is to bring amino acids to the ribosomes to be assembled into proteins.

• RNA polymerase manifests itself as the main transcription enzyme in the synthesis of RNA.
• Transcription is the unique process of copying a DNA sequence into an RNA sequence.
• The RNA polymerase does bind to a promoter sequence at the beginning of a gene either directly or with the help of helper proteins to initiate the process of transcription.
• In the transcription process, RNA polymerase utilizes one of the DNA strands as a template to create a "new, complementary RNA molecule".
• The process in which the ribosomes act as unique machinery to construct a protein from the amino acids according to the code of DNA, the transfer-RNA or tRNA plays a crucial role.
• The transfer-RNA or tRNA ensures the transfer of the absolute right amino acid into the growing chain of the protein as the assembly continues protein-synthesis, in line with the code of the DNA.
• Thus the role of RNA polymerase is that it helps transcribe the DNA strand and the purpose of the transfer-RNA is to bring amino acids to the ribosomes to be assembled into proteins.
