If a scientist observes an enzyme polypeptide chain arranged in spiral turns that rise upward and are held in place by hydrogen bonds he/she is looking at a tertiary structural arrangement.
In eukaryotes, DNA is found in chromosomes in the nucleus. Chromosomes are made of a single molecule of DNA and proteins. Chromosomes are linear, and DNA in them is double stranded. There are many chromosomes in a single nucleus. In prokaryotes, a single DNA molecule which is double stranded forms the chromosome. There are no proteins in the chromosome. In viruses, the genetic material is either DNA or RNA. They may be double stranded or single stranded. It may be circular or linear.
Answer:
First of all, scientists are sending off our DNA to other secrect agencys to study, so they can learn about our DNA and break it down. Killing humans, espically African Americans. They put these chemicals in commonly used products like lotion, wax, and medicine. So what makes people think they have the right to use it as evidence to solve crimes? WE CAN'T EVEN TRUST THEM ON THE REGULAR.
Explanation:
If you look this up on the internet, obviously it won't be there because they are trying to get paid. Hope this helps! :)
Much of the coordination of vertebrate body functions via chemical signals is accomplished by the endocrine system.
The endocrine system is an information system composed of hormonal feedback loops that are secreted directly into the circulatory system by the body's endocrine glands and regulate distant target organs.
In vertebrates, the hypothalamus is the centre of neuromodulation of all endocrine systems. The main endocrine glands in humans are the thyroid and adrenal glands.
The study of the endocrine system and its disorders is called endocrinology.
The glands that send signals to each other in sequence are often referred to as the hypothalamic-pituitary-adrenal axis.
In addition to the specialized endocrine organs mentioned above, many other organs that are part of other body systems have secondary endocrine functions such as bones, kidneys, liver, heart and gonads.
For example, the kidneys secrete the endocrine hormone erythropoietin. Hormones are amino acid complexes, steroids, eicosanoids, leukotrienes, or prostaglandins.
