The answer to the given question has been solved as under;
Ans 68) The correct option is (a) alternative splicing.
Ans 69) Transacting transcriptional regulators are proteins that bind at specific DNA sequence in the vicinity of a structural gene and regulates gene expression. An example would be the components of RNA Polymerase that bind at promoter of a gene.
Ans 70) Cis acting transcriptional regulators are DNA sequences that are conserved among species in the vicinity of a gene that regulate gene expression by acting as binding sites for transacting factors. Example include promoter sequence, enhancer elements, operator site.
Ans 71) RNAi is an example of post transcriptional gene silencing mechanism.
Ans 72) CRISPR-Cas9 is an example of gene editing tool.
