No because it changes letters so the primer will not be the correct match. They have to be different.

For example, the original DNA strand is AATGCGTACTAGCTAGTCTTAGTC and the primer is TTACGC. There is no other match to the DNA strand so a new one will have to be used.

What is the most common form of DNA found in organisms?

I believe there is only one form of DNA. There are numerous forms of RNA. The least common RNA molecule is tRNA as it is stimulated by the protein synthesis cycle and is only produced at certain times.


Which organelle contains all of your DNA or your entire genetic make-up?

The nucleus. Mitochondria also contain DNA, but not your whole genome. Your mitochondrial DNA comes only from your mother.


Which cells have DNA as their genetic material?

Haploid cells like sperm cells,ova,bacteria


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.

b. it could carry and make copies of information

In polymerase chain reaction how many kinds of primer are used?

In polymerase chain reaction (PCR), two types of primers are used: a forward primer and a reverse primer. These short DNA sequences are specific to the target DNA region to be amplified and serve as starting points for DNA synthesis by the DNA polymerase enzyme.


What controls which DNA is amplified in PCR?

In PCR, the primers used to identify the target sequence on the DNA template determine which DNA is amplified. The primers are designed to match specific regions flanking the target sequence, allowing them to bind and initiate DNA synthesis. This specificity ensures that only the desired DNA fragment is amplified.


Use E co RI and MseI in AFLP analysis?

Chop DNA into pieces using you restriction enzyme(s) of choice. Add adapter to sticky end, you know the sequence of the sticky end as it corrisponds to the restriction enzyme used. Use a primer for the adaptor and amplify the DNA with PCR. Ta dah you just amplified somthing you didn't have a primer for. Run the amplified DNA on a gel and you can see changes between your samples.


Why does DNA polymerase require a primer for initiating the synthesis of new DNA strands?

DNA polymerase requires a primer to initiate the synthesis of new DNA strands because it can only add nucleotides onto an existing strand of DNA. The primer provides a starting point for the polymerase to begin adding nucleotides and building the new DNA strand.


What is the significance of observing no bands on gel electrophoresis following PCR amplification?

Observing no bands on gel electrophoresis after PCR amplification indicates that the target DNA sequence was not successfully amplified. This could be due to issues such as primer design, PCR conditions, or the quality of the DNA sample. It is important to troubleshoot and optimize the PCR reaction to ensure successful amplification of the desired DNA fragment.


What does the first nucleotide attach to because DNA polymerase can only add nucleotides to a pre-existing strand?

A primer molecule is required for DNA polymerase to initiate the addition of nucleotides. This primer provides a starting point for DNA polymerase to begin adding nucleotides in the correct sequence. Once the primer is in place, DNA polymerase can add nucleotides complementary to the template strand.


What is a RNA primer removed by?

A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.


During DNA duplication primer called RNA primer why?

During DNA duplication, an RNA primer is used because DNA polymerase can only add new nucleotides to an existing nucleic acid strand rather than initiating synthesis. The RNA primer provides a starting point for DNA polymerase to bind and begin adding complementary nucleotides to synthesize a new DNA strand. This primer is later removed and replaced with DNA nucleotides to complete the replication process.


What enzyme Cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides?

The enzyme that cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides is DNA polymerase I in prokaryotes and DNA polymerase delta in eukaryotes. This process, known as primer removal or primer excision, is essential for completing DNA replication accurately.


Which of the following enzymes creates a primer for DNA polymerase?

DNA primase is the enzyme that creates the RNA primer needed for DNA polymerase to initiate DNA synthesis.


For DNA polymerase to link nucleotides together as new strands of DNA the first nucleotide must be attached to what because DNA polymerase can only add nucleotides to a pre exsisting strand?

The first nucleotide must be attached to a short RNA primer to provide a free 3' hydroxyl group for DNA polymerase to extend from. DNA polymerase starts adding nucleotides to this RNA primer to begin DNA replication.


For DNA polymerase to link nucleotide together as new strands of DNA the first nucleotide must be attached to a because DNA polymerase can only add nucleotides to a pre-existing strand?

For DNA polymerase to link nucleotides together, the first nucleotide must be attached to a primer, which is a short segment of RNA or DNA that provides a free 3' hydroxyl group for the DNA polymerase to start adding nucleotides. DNA polymerase can only extend nucleotides from an existing primer or strand, using it as a template for complementary base pairing.
