DNA and histone proteins are packaged into structures called chromosomes. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.Chromosomes are not visible in the cellâs nucleusânot even under a microscopeâwhen the cell is not dividing.ach chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Answers. Best Answer: The invention of the minie ball, coupled with the invention of the rifle-musket, allowed for faster shooting and more devastating injuries.The minie ball is shaped like the modern bullet, and shatters on impact.The musket ball, round and circular, would not fracture inside the body, making it easy to pull out. Other important inventions were the Gatling gun, the repeating rifle, and ironclads.he musket ball, round and circular, would not fracture inside the body, making it easy to pull out.

The shape of these bullets causes a bubble of gasâwater vaporâto be generated and trapped around them while underwater. This bubble has far less drag on it than water against metal, and with just the point of the bullet in contact with water, they can travel through a lot more water than your run of the mill softpoint.hese individually-machined bullets can travel many times farther through water than conventional bullets via supercavitation. Their first design is a very long, hollow and heeled .308-inch diameter bullet for .308 Winchester cartridges.
