Answer:

Explanation:

In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.

So square 1, on the left is A, and on the top is A, so it would be AA.

For square 2, on the left is a, and on the top is A, so it would be Aa.

For square 3, on the left is A, and on the top is A, so it is AA.

Square 4, your question, has a on the left, and A on the top, so it is Aa.

Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.

Under what conditions does the trp repressor block transcription of the trp operon? (A) when the repressor binds to the inducer

Brilliant_brown [7]

The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.

trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.

Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.
