biology question

the question is: suggest how the inserted gene reduces the production of the softening enzyme
softening gene mRNA- AAUCGGAAU
inserted gene mRNA - UUAGCCUUA

please help I really don't understand!

Do you have an image or the whole text of the question (since this looks like a part of a question)?

Are you familiar with competitive (and non-competitive) inhibitors?

As you can see from the sequence, they are both complimentary to each other. Therefore it can bind to the normal gene to prevent protein synthesis by preventing it from binding or reaching the ribosome.

Another marking point is that not all of the normal gene will be bounded by inserted genes, so some enzymes will still be produced

oh so does the inserted gene reduce the production of softening enzyme because its is complementary?

Complimentary to the normal softening mRNA strand yeah. When two complimentary strand come into contact, hydrogen bonds form (bases in the mRNA aren't exposed, so similar to DNA), and therefore tRNA molecules would not be able to attach to the starting codon.
