Answer:the probability of their first two offspring being aa is 0.25
Explanation:
Because their are 4 possible genotypes for the offsprings
AA Aa Aa aa
And the probability of aa is 1/4
Answer:
The given blank can be filled with operator.
Explanation:
The proteins that assist in turning on or turning off the function of a specific gene by getting combined with certain sections of the DNA are known as transcription factors. The transcription factors that activate the transcription of a specific gene are known as activators, while that prevents transcription and is termed as repressors.
A repressor can be an RNA or a DNA binding protein, which prevents the articulation of genes by getting combined with the operator. A repressor, which binds with DNA prevents RNA polymerase from getting combined with the promoter, which further inhibits the transcription of the genes into mRNA.
Answer:
To balance the production of certain products.
Explanation:
Feedback inhibition is when byproduct from metabolic reactions in cells accumulates and is in excess. The product goes and inhibits the enzyme that is responsible for speeding its chemical reaction, balancing the amount of product needed, with the amount already produced.
Therefore feedback inhibition is important in metabolic pathways because it balances the production of amino acids and nucleotides. It is there to ensure that the exact amount needed is produced.
I believe the correct answer among the choices presented above is option A. The flow that correctly shows how genes are inherited is DNA→ RNA→ protein→ trait. The DNA gets transcripted into RNA which is translated to the proteins which turns into traits.
