Although miRNA and siRNA both have gene regulation functions, there are subtle differences. MiRNA may be slightly shorter than siRNA (which has 20 to 25 nucleotides). MiRNA is single-stranded, while siRNA is formed from two complementary strands. The two kinds of RNA are encoded slightly differently in the genome. And the mechanism by which they regulate genes is slightly different.

MiRNA attaches to a piece of messenger RNA (mRNA) -- which is the master template for building a protein -- in a non-coding part at one end of the molecule. This acts as a signal to prevent translation of the mRNA into a protein. SiRNA, on the other hand, attaches to a coding region of mRNA, and so it physically blocks translation.

Is helicase involved in the process of transcription?

No, helicase is not directly involved in the process of transcription. Transcription is the process of making an RNA copy of a gene's DNA sequence, while helicase is primarily involved in unwinding the DNA double helix during processes like DNA replication.


Is DNA polymerase used in the process of transcription?

No, DNA polymerase is not used in the process of transcription. Transcription is the process of making an RNA copy of a gene from DNA, and it is carried out by an enzyme called RNA polymerase. DNA polymerase is primarily involved in the process of DNA replication.


Does transcription require RNA polymerase for the synthesis of RNA molecules?

Yes, transcription requires RNA polymerase for the synthesis of RNA molecules.


What is transcription and what are the main steps involved in this process?

Do your own lab report. Jk. Transcription is the process in which DNA is converted into a complementary RNA. Before transcription, the splicing of introns has already occurred. Transcription takes place the nucleus. RNA polymerase begins the elongation of the RNA while the DNA template is unwound and rewound. Transcription responds to the termination signal and disassembles, terminating the process. The RNA is then processed with 5' G cap and poly A tail, and exits the nucleus, heading into the cytoplasm.


What is the process of making RNA from DNA called?

The process that involves the transcribing of genetic information from DNA to RNA is called Transcription.

What two nucleic acids are involved in transcription?

Transcription involves the synthesis of RNA from a DNA template. The two nucleic acids involved are DNA, which serves as the template for RNA synthesis, and RNA, which is the product of transcription.


What enzyme is involved in RNA elongation?

RNA polymerase is the enzyme involved in RNA elongation. It adds nucleotides to the growing RNA chain during transcription.


Will you please explain transcription parts and steps involved?

Transcription is the process of copying genetic information from DNA to RNA. The steps involved are initiation, where RNA polymerase binds to the promoter region of DNA, elongation, where RNA polymerase adds complementary RNA nucleotides to create an RNA strand, and termination, where RNA polymerase stops transcription and releases the RNA strand. The resulting RNA molecule can then be used to produce proteins during translation.


What is RNA transcription and where does it take place?

RNA transcription is when RNA coverts into DNA, which takes place in the ribosomes.


Is helicase involved in the process of transcription?

No, helicase is not directly involved in the process of transcription. Transcription is the process of making an RNA copy of a gene's DNA sequence, while helicase is primarily involved in unwinding the DNA double helix during processes like DNA replication.

DNA passes information to RNA during what process?

Transcription. DNA serves as the template for the synthesis of RNA molecules through transcription. During transcription, the information encoded in the DNA is transcribed into a complementary RNA sequence by RNA polymerase.


Does RNA polymerase require a primer for transcription?

No, RNA polymerase does not require a primer for transcription.


The process in which DNA makes RNA is called?

Transcription. During transcription, an enzyme called RNA polymerase reads the DNA sequence and synthesizes a complementary RNA molecule. This RNA molecule serves as a template for protein synthesis.
