What is the complementary strand of DNA and RNA?

Mar 28, 2011 · For instance, miR-208 was found to persist in the absence of its precursor for >12 days in heart tissue and miR-122 levels remained unchanged following rapid decrease of pri-miR-122 in liver tissue . Conversely, a rapid decrease of miRNAs has been observed in neuronal cells, following blocking of pri-miRNA transcription ( 14 ).

Can two complementary DNA strands from different sources pair with one another?

What is the sixth subunit of RNA polymerase?

The sixth subunit is known as sigma (σ). The σ factor enables RNA polymerase to bind to a specific promoter, thus allowing for the transcription of various genes. There are various σ factors that allow for transcription of various genes.

What is the process of making RNA?

During transcription, the information encoded in DNA is used to make RNA. RNA polymerase synthesizes RNA, using the antisense strand of the DNA as template by adding complementary RNA nucleotides to the 3′ end of the growing strand. RNA polymerase binds to DNA at a sequence called a promoter during the initiation of transcription.

What is the difference between DNA and RNA polymerase?

One critical difference in activity between DNA polymerase and RNA polymerase is the requirement for a 3′-OH onto which to add nucleotides: DNA polymerase requires such a 3′-OH group, thus necessitating a primer, whereas RNA polymerase does not.

What is the RNA molecule composed of?

The resulting single-stranded RNA molecule, composed of ribonucleotides containing the bases adenine (A), cytosine (C), guanine (G), and uracil (U), acts as a mobile molecular copy of the original DNA sequence. Transcription in prokaryotes and in eukaryotes requires the DNA double helix to partially unwind in the region of RNA synthesis.

What is the bubble in transcription?

Transcription in prokaryotes and in eukaryotes requires the DNA double helix to partially unwind in the region of RNA synthesis. The unwound region is called a transcription bubble. Transcription of a particular gene always proceeds from one of the two DNA strands that acts as a template, the so-called antisense strand.

How is RNA synthesized?

Explain how RNA is synthesized using DNA as a template. Distinguish between transcription in prokaryotes and eukaryotes. During the process of transcription, the information encoded within the DNA sequence of one or more genes is transcribed into a strand of RNA, also called an RNA transcript. The resulting single-stranded RNA molecule, composed ...

Which enzyme is used to transcribe genes?

Transcription in Bacteria. Bacteria use the same RNA polymerase to transcribe all of their genes. Like DNA polymerase, RNA polymerase adds nucleotides one by one to the 3′-OH group of the growing nucleotide chain.
