Explain why the precise length target DNA sequence doesn't get amplified until the third cycle?
In the first polymerization step, a new DNA strand is synthesized onto each primer. Taq polymerase extends this new strand well beyond the target sequence, producing a new DNA strand that contains the downstream/upstream primer and is longer than the target. In the second cycle, the DNA is denatured and primers anneal to the original target DNA and to the new DNA strands produced in the first cycle. A mixture of small target sequences and larger hybrid DNA sequences are produced at the end of the second cycle. In the third cycle, the target DNA of defined length is reprimed with both upstream and downstream primers. Taq polymerase then synthesizes two copies of target DNA of defined length. The number of these defined target sequences is doubled with each subsequent round of PCR, thereby increasing logarithmically. Thus, a 40 cycle PCR would amplify a given template 240 , thus potentially producing 1.0 x 1012 DNA molecules. In the first polymerization step, a new DNA strand is synthesized onto each primer.

What questions might scientists have asked following the discovery of cyclin?
Scientists might have asked how cyclin levels are regulated during the cell cycle, what specific role cyclin plays in regulating cell division, and whether abnormalities in cyclin expression or function are associated with diseases like cancer.
What is a cyclin and what does it activate?
Cyclins are proteins that regulate the cell cycle by binding to cyclin-dependent kinases (CDKs). This binding activates the CDKs, leading to the phosphorylation of target proteins that drive the cell cycle progression.
What is the function of cyclin in eukaryotic cells?
Cyclins are proteins that regulate the progression of the cell cycle by binding to cyclin-dependent kinases (CDKs), activating them to trigger different stages of the cell cycle. Cyclin-CDK complexes control the transition from one phase of the cell cycle to the next by phosphorylating target proteins that regulate cell cycle progression.
Which of the following is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?
Cyclin is a protein synthesized at specific times during the cell cycle that associates with a kinase (CDK) to form a catalytically active complex. Cyclin-CDK complexes regulate the progression of the cell cycle by phosphorylating various target proteins.
What types of scientists studies water and the water cycle cycle?
Hydrology
Who are the target customers for cycle menu?
The target customers for cycle menu are university student and local and international tourists. This is because they are usually stationed at their respective places at different times.
What term do scientists use for the portion of the water cycle that takes place within the biosphere?
Its Hydro logical cycle
What was the water cycle rainfall event in the 1980s?
Since the mid 1980s scientists believe the water cycle has intensified.
How can technology help scientists form a better rock cycle model in the future?
My only opinionn is that technology keeps growing and enhanced so it can help scientists in many ways not just for rock cycle. But specifically on rock cycle, they can create creative, realistic or other ways in expressing the rock cycle.
What is the difference between target costing and life cycle costing?
In Target costing system, comapnies tries to achieve target prices by reducing those parts of activity which are not increasing the value of product. Life cycle costing is a concept in which companies tries to read the overall process of development of product life cycle and tries to minimise the cost at area where it is not required or not increase the value of product.
Where can you find the last book in the inheritance cycle?
You can buy it anywhere. Target, QBD, Kmart.

How do you say 'the question is' differently?
Rather than saying first, "The question is...", just ask the question. It is much more direct.If you must use the phrase, you could change it to a statement that raises the question:I'm wondering if (then your question).When you consider that (whatever is true), (then your question).Scientists have questioned whether (write the question).Examples:I'm wondering if you plan to go to the party.When you consider that the evaporation cycle depends on the oceans, what effect does pollution have on the evaporation-rain cycle?Scientists have questioned whether global warming has increased or if it is part of a normal cycle of warming.
How do you preserve the rock cycle?
Nothing you could do without intent could disrupt the rock cycle. There is no need for you to worry.
What is an example of phosphorylation?
It could be the krab cycle/citric acid cycle
