Which of the following attributes is common to both prokaryotic cells and eukaryotic cells? (concept 1.1)a) the use of dna as the information storage moleculeb) membrane-enclosed organelles. c) prokaryotic and eukaryotic cells are generally about the same size. d) the use of proteins as information storage molecules. e) a membrane-enclosed nucleus

A

Explanation:

Prokaryotic and eukaryotic cells share some attributes including that they store genetic inormation using deoxyribonucleic acids (DNA). Other similarities include that both are membrane-bound (both have a bilipid layer cell membrane).  

The major differences between the two are that the organelles of eukaryotes are membrane-bound unlike in prokaryotes and that prokaryotes are generally smaller in size compared to eukaryotes.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
