Questions
Question 1:
a) Based on the information given to you in the lecture, do you think it is possible to find a single “addiction gene” that determines if someone will become addicted to a substance? Why or why not? Give an example to support your statement.
If someone becomes addicted to any substance in many of the cases it can be seen that there are multiple numbers of genetic alterations or any other mutation are being seen. Through a huge set of identification methods those modifications can be detected. In the case of a single addiction gene it can be possible to find that single gene by tracking the genome sequence. By the implementation of the single nucleotide polymorphism method the detection of that single gene can be possible. Finding the specific loci of the gene the genetic alteration can be detected. An example of nicotine addiction can be mentioned here. In the case of nicotine addiction it can be seen that it metabolites the DNA by the process of methylation. At the time of the transcription and translation the methylated DNA sequence indicates a mismatch with the mRNA sequence and produces another protein.
b) In the lecture I talked about the high heritability of cocaine addiction. Why do you think this is? (hint: I talked about it. Use your own words, not mine!)
Through several studies it can be confirmed that there is a higher chance of the heritability of cocaine addiction. In case of the addiction of the cocaine it modifies the genetic sequence or the genetic linkage of any specific gene. Here due to this modification the misinterpretation of the genetic signal can be found. There is a huge probability to transmit those modified sequences to the next generation. Apart from that...
