Question

1.Match the type of cellular control with the description.

2. Match each component with one of the following descriptions. Drag the appropriate labels to their respective targets.

Match the type of celular controi with the description Drag the appropriate labels to their respective targets The substrate induces the synthesis of its own metabolic enzymes. The end product of a reaction combines with the regulator to produce a repressor molecule that urns off the When substrate is present in the cell the structural gene produaces mRNA for enzyme synthesis enzyme inducton The end product of a reaction pathiway controls protein nnthesis The substrate of a reaction pathneay controls protein synthesss

Explanation / Answer

1) Enzyme Induction

- The substrate induces synthesis of its own metabolic enzymes

- When the substrate is present in the cell, the structural gene produces mRNA for enzyme synthesis

- The substrate of a recation pathway controls protein synthesis

Enzyme Repression:

- The end product of a reaction combines with the regulator to produce a repressor molecule that turns off the operator gene.

- The end product of a reaction pathway controls protein synthesis

2)

Leading Strand - daughter DNA synthesized continuously in 5' to 3' direction

DNA Ligase - catalyzes the formation of phosphodiester lihkages between nucleotides

Single-Strand Binding Protein - attaches to unwound strands to keep them open

DNA-Polymerase - combines Okazaki fragments to form daugter DNA strand
