Apersons skin cells and eye make different types of proteins to perform their functions. what's is the source of the instructions from which all of the proteins are made

From DNA

Explanation: DNA is the inheritance molecule in humans and carries the information for every protein needed for our metabolism. DNA is transcripted to produce RNA and this is translated to produce proteins. Each type of cells has the same DNA (With some variations due to mutations in life) but their DNA express differently according to their specialized function.

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.
