Which enzyme synthesizes a short RNA primer at the beginning of each origin of replication?
DNA polymerase III can add nucleotides only to a chain of nucleotides that is alreadypaired with the parent strands. Hence, DNA polymerasecannot link the first nucleotides in a newly synthesizedstrand. Instead, another enzyme, an RNA polymerasecalled primase, constructs an RNA primer, a sequence ofabout 10 RNA nucleotides complementary to the parentDNA template. DNA polymerase III recognizes the primerand adds DNA nucleotides to it to construct the new DNAstrands. The RNA nucleotides in the primers are then replacedby DNA nucleotides.
Repair of damaged DNA might be viewed as a race between an endonuclease and?
a DNA polymerase. The endonuclease recognizes and cleaves the damaged DNA, creating a site for repair. The DNA polymerase then fills in the gap with the correct nucleotides, restoring the integrity of the DNA molecule. This race determines whether the DNA is successfully repaired or if mutations will persist in the repaired sequence.
What recognizes a hormone's chemical structure?
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.

What event occurs directly after RNA polymerase recognizes the transcription start of a gene?

How does a Tata box helps position rna polymerase. In a eukaryotic cell?
The TATA box seems to help position RNA polymerase by marking a point just before the point at which transcription begins.

Role of component used in PCR?
TemplateThe template consists of the DNA region which will be amplified during the reaction. The template is one of the two strands in the double helix and is the point where the new strand will start to be built.Primers:There are two primers that are complemantary to the 3’ on the DNA strand. Without them the reaction can’t start.DNA polymerase:The DNA polymerase is a polymerase enzyme that builds/synthesizes DNA molecules out of its own nucleotide building blocks. This enzyme is essential for DNA replication (which is why it’s being used in PCR) and usually, it is working in pairs since it transforms a double stranded DNA molecule into two double-stranded helixes.MgCl2 concentration:Forms a soluble complex together with dNTP which produces the substrate that the polymerese recognizes. Without this, the polymerase will have trouble starting, if at all.dNTP (Deoxynucleoside triphosphate):These are nucleotides which contains triphosphate groups. These groups, also commonly named “building blocks”, are the ones from which the DNA polymerase synthesizes a new DNA strand.
The three domain system recognizes fundamental differences between two groups of?
It recognizes fundamental differences in prokaryotes.
