D) transposable elements
E) paternal DNA

Question

Quizplus · Accepted Answer

After fertilization, the maternal mRNA stored in the egg is responsible for initiating translation. This mRNA contains instructions for early developmental processes, and its translation is crucial for the formation of the zygote. Paternal promoters in sperm and paternal DNA also contribute to zygote formation but are not directly involved in the initiation of translation. Maternal transcription factors are involved in gene regulation but not translation initiation, and transposable elements are DNA sequences that can move around the genome and are not involved in translation initiation.
