Question

Транскрипцию катализирует:а)РНК-рестриктоза,б)ДНК-эндонуклеоза, в)ДНК-полимераза,г)РНК-полимераза,д)РНК-транскриптоза,е)ДНК-транскриптоза

Answer 1

Ответ: г) РНК-полимераза

Транскрипция осуществляется ферментом РНК-полимеразой, строящей, согласно принципу комплементарности, копию участка ДНК на основании одной из цепей двойной спирали.

Answer 2

Transcription is catalyzed by:

a) RNA-restrictase b) DNA-endonuclease c) DNA polymerase d) RNA polymerase e) RNA transcriptase f) DNA transcriptase

Transcription is the process by which genetic information encoded in DNA is copied into RNA. It is catalyzed by an enzyme called RNA polymerase. RNA polymerase recognizes specific DNA sequences called promoters and binds to them, initiating the transcription process. During transcription, the RNA polymerase unwinds the DNA double helix and synthesizes a complementary RNA strand using one of the DNA strands as a template.

a) RNA-restrictase is not a known enzyme involved in transcription. It is possible that you may be referring to a different enzyme or process.

b) DNA-endonuclease is an enzyme that cleaves DNA at specific sites. It is not directly involved in the process of transcription.

c) DNA polymerase is an enzyme that synthesizes DNA strands during DNA replication. It is not directly involved in the process of transcription.

d) RNA polymerase is the enzyme responsible for catalyzing transcription. It recognizes specific DNA sequences and synthesizes an RNA molecule complementary to the DNA template strand.

e) RNA transcriptase is not a commonly used term in molecular biology. It is possible that you may be referring to RNA polymerase, which is responsible for catalyzing transcription.

f) DNA transcriptase is not a commonly used term in molecular biology. It is possible that you may be referring to RNA polymerase, which is responsible for catalyzing transcription.

In summary, the enzyme that catalyzes transcription is RNA polymerase. It recognizes specific DNA sequences and synthesizes an RNA molecule complementary to the DNA template strand.
