What type of connective tissue is composed of many interwoven and randomly organized collagenous fibers?

Dense irregular connective tissue is the type of connective tissue is composed of many interwoven and randomly organized collagenous fibers

Dense irregular connective tissue is found in several locations: the dermis of the skin, the walls of large tubular organs, such as the alimentary canal, in glandular tissue, and in organ capsules.

There are differences between Dense irregular connective tissue and Dense regular connective tissue.

Dense Regular Connective Tissue  is consists of closely packed bundles of collagen fibers running in the same direction. Also these collagen fibers are slightly wavy and can stretch a little bit.  With the tensile strength of collagen, this tissue forms tendons, aponeurosis and ligaments. This tissue forms the fascia, that is a fibrous membrane that wraps around the muscles, blood vessels, and nerves.  

Whereas Dense Irregular Tissue  has the same structural elements as dense regular tissue, but collagen fibers bundles are much thicker and arranged irregularly. This tissue is found in areas where tension is exerted from many different directions. It is part of the skin dermis area and in the joint capsules of the limbs.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
