Control of (blank) synthesis is the key to controlling the chemical pathway of the cell.

strojnjashka [21]

Controlling the synthesis of proteins is the key to controlling the chemical pathways in the cell.
This is because proteins have key roles in many chemical reactions in the cell.
The most important proteins for the chemical reactions in the cell are enzymes.
Enzymes catalyze many chemical reactions, therefore, the control of the enzyme synthesis is a direct way of controlling other chemical reactions in the cell.

Predict the type of progeny produced by Mendel's crosses between pure-breeding plants with discrete, antagonistic traits, such a

asambeis [7]

Answer:

The progeny produced is 100% heterozygous individuals.

Explanation:

Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.

When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.

If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.

As for its phenotype, it will depend on which allele is dominant over the other.
