G How would genetically engineered proteins likely change in organisms living in cold temperatures?

There are several genetically modified species of plants that contain special proteins sequences in their genome to withstand freezing temperature. These have been developed by studying the CRG's (Cold Regulating Genes) in mustard plants living at freezing temperature. These proteins sequences are mostly similar in all protiens as studied in their genome and work like anti-Heat Shock proteins. All of these actions against cold are regulated by a hormone named Vernaline (A Type Of Gibberalins)

Option D is correct.

Explanation:

Option a) given in the option that if promoter is altered it will inhibit transcription which is the process by which information present in DNA converted to mRNA which require RNA polymerase which bind to promoter site so if promoter is altered RNA polymerase will not bind so transcription will be inhibited but above question is asking about inhibition of translation due to binding of miRNA-delta molecule to Q mRNA so this option can be eliminated.

Option b if miRNA binding site sequence is altered miRNA molecule will not be able to bind to Q mRNA so translation will not be inhibited hence option b is incorrect

Option c translation of Q mRNA is inhibited when miRNA - delta is present not absent

So option c can be eliminated

Option d if miRNA binding sequence is altered miRNA molecule if present will not bind to Q mRNA hence translation of Q mRNA will occur & not inhibited

Hence option d is correct
