The proteins that are synthesized after egg activation by sperm entry are from maternal mRNAs that were already present in the egg. This is because the egg is already fully equipped with all of the necessary components to support early development, including the required mRNAs. The sudden increase in protein synthesis is triggered by the entry of the sperm, which provides the signal or stimulus for the egg to reprogram its metabolism and activate these maternal mRNAs. The proteins that are synthesized in response to this signal are therefore derived from the existing pool of maternal mRNAs, rather than from any newly introduced paternal mRNAs or histone proteins.
