In an experiment, the hybridization method could identify quail in one of the pâté, but the PCR method could not differentiate between different pâté samples. Why? (limit 100 words)

Expert Solution

One of the most convenient methods for the identification of animal species in processed meat products is the examination of DNA sequences.Real-time polymerase chain reaction (qPCR) techniques are particularly suitable because even small fragments of DNA formed during heat processing of the meat can be amplified and identified.

But The PCR method could not differentiate between the different pâté samples as the amplification of the mitochondrial cytochrome c oxidase subunit 1 (COI) is only highly useful against identification of bird, butterflies, fish and flies and not toward specific species of organisms, at current circumstance quails. Despite the fact thatPCR method failed to distinguish between pâtés, it did however provided information that our pâté samples are identified as avian. The hybridization method could identify quail on account of the fact that the quail mtDNA-CR probe is specific to mitochondrial DNA of the quail.

A professor at a local university designed an experiment to see if someone could identify the color of a candy based on taste alone. Students were blindfolded and then given a red-colored or yellow-colored candy to chew. (Half the students were assigned to receive the red candy and half to receive the yellow candy. The students could not see what color candy they were given.) After chewing, the students were asked to guess the color of the candy based on the flavor. Of the 122122...

A student attempted to identify an unknown compound by the method described in this experiment. When he heated a sample weighing 1.031 g the mass went down to 0.688 g. When the product was converted to a chloride the mass went up to 0.748 g. (Answers I got are in bold) 1.Explain if you believe the sample to be a carbonate or hydrogen carbonate. (I said it is a hydrogen carbonate due to the loss of mass) 2.Write the two...

1. A student attempts to identify an unknown compound by the method used in this experiment. She finds that when she heated a sample weighing 0.5015 g the mass went down appreciably, to 0.3432 g. When the product was converted to a chloride, the mass went up, to 0.3726 g. a. Is the sample a carbonate? ____________ Give your reasoning. b. What are the two compounds that might be in the unknown? ____________ and ____________ c. Write the chemical equation...
