Answer:
Carboxylating pyruvate into oxaloacetate.
Explanation:
Replenishing oxaloacetate is done by carboxylating pyruvate into oxaloacetate through a process that is catalyzed by an enzyme called pyruvate carboxylase. This enzyme speed up the process and the replenishing of oxaloacetate occur quickly and the oxaloacetate is ready to function and participate in different chemical reactions.
Answer:
B. the action of microRNAs that block translation of specific mRNA molecule
C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.
Explanation:
RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.
MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.
RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
