The source of the necessary elements of life is.

. E All of the above. C You can see the DNA moving in the gel. Which STR will have migrated farthest through an electrophoresis gel.

During PCR a chimera can form when the extension of an amplicon is aborted and the aborted product functions as a primer in the next PCR cycle. Electrophoresis works by running an electrical charge through the gel. PCR uses a DNA polymerase to synthesize DNA D.

DNA polymerase is the enzyme that copies DNA in PCR. The number of times the sequence is repeated. The following statements are usually true.

Which statement about PCR is true. Which of the following statements are true regarding PCR. PCR can be used to obtain large quantities of a particular DNA sequence E.

Question 7 5 points Which of the following statements are true about metagenomics. For Taq polymerase to form new copies of DNA. Which of the following statements are true regarding PCR.

A Primer extension occurs at 72C b Denaturation involves heating at 90 to 98C c Annealing involves the binding of primer between 40 to 60CC d All of. C PCR reaction products can be used in molecular cloning. B PCR is often used in forensics laboratories.

A PCR reaction that contains only one copy of the target sequence 1 copy reaction a. B You can see the loading dye move from the well into the gel. DNA polymerase from Thermus aquaticus is used in PCR because A it is a soluble protein.

Branched DNA is more sensitive than Ligase chain reaction. The polymerase chain reaction PCR is used to generate many copies of deoxyribonucleic acid DNA and the enzyme Taq polymerase is used because they are able to withstand high temperatures that are isolated from the microorganism Thermus aquaticus. Linear amplification occurs in branched DNA.

DNA polymerase is the enzyme that copies DNA in PCR. PCR is extremely liable to contamination. An organic nutrient essential to an organisms metabolism that cannot be synthesized itself is termed aan.

E it is not infectious. Denaturation annealing and extension. PCR does not require nucleotides.

Is typically amplified in a highly repeatable manner b. Which of the following statements about PCR is true. It correlates with a lower probability of developing dementia.

PCR is more sensitive than branched DNA assays. C the enzyme is readily deactivated by heat effectively halting the reaction. PCR does not require knowledge of the DNA sequences at the ends of the region to be amplified.

Which of the following is true regarding PCR. PCR uses short oligonucleotide primers C. May amplify but is detection is not likely to be highly repeatable.

Multiple Choice Questions From Chapters 7-12. B micronutrient c growth factor d essential nutrient 2. DNA has a negative charge.

It correlates with a lower probability of developing metabolic diseases when engaging in intense exercises for at least 60 minutes every day of the week.
