Answer: The article read by Yuki is more likely to have been peer-reviewed because this article is part of a Journal Medicine and peer-review is mandatory in most Academic journals before publication.
Explanation:
Peer-review implies academic works such as research papers or articles are verified by peers of the author. For example, a medical article is evaluated by other experts in the same field with similar knowledge and competences. This process is essential to guarantee the information is accurate and reliable. Moreover, peer-review is used mainly in academic journals or academic papers. Indeed, most academic journals require new articles or papers to be peer-review before these are published in the journal.
In this context, it is likely the article red by Yuki has been peer-reviewed because this is part of a Medicine journal and it is a general standard for articles in journals to be reviewed. Also, this is not a requirement for articles published in regular magazines such as Tasty Food magazine.

Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
Answer:
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Hopefully this helped! :D
