Well everything is made of complex proteins. There isn't one single organism just comprised of proteins. For example keratin is a protein that is made when RNA passes through a ribosome. Now this protein may be used in different functions, one is to strengthen hair/nails. To simplify: anything living that is eukaryotic. (multi_cellular organisms bigger than bacteria and viruses.)
Mammalian fertilization comprises sperm migration through the female reproductive tract, biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct. Recent gene knockout approaches in mice have revealed that many factors previously considered important for fertilization are largely dispensable, or if they are essential, they have an unexpected function. These results indicate that what has been observed in in vitro fertilization (IVF) differs significantly from what occurs during “physiological” fertilization. This Review focuses on the advantages of studying fertilization using gene-manipulated animals and highlights an emerging molecular mechanism of mammalian fertilization.
Double helix is the correct answer
