1. Describe the structure of an atom? The subatomic particles that make up atoms are protons‚ neutrons‚ and electrons. 2. Why do all isotopes of an element have the same chemical properties? In what way do isotopes of an element differ? An isotope has the same number of protons but a different number of neutrons in the nucleus. 3. What is a covalent bond? An ionic bond? An ionic bond is formed when one or more electrons are transferred from one atom to another. Covalent bond forms when

Protein is important! 1Protein is important because its an essential nutrient found in animal products‚ nuts‚ and beans. The name protein name comes from the Greek word protos‚ which means “first.” Your body uses proteins in your diet to build new cells‚ maintain tissues‚ and synthesize new proteins that make it possible for you to perform basic bodily functions. To visualize a molecule of protein‚ close your eyes and see a very long chain‚ rather like a chain of sausage links. The links in the

to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic cycle. In the lytic cycle‚ viral particles

Nucleus contain DNA replication and synthesizes RNA‚ while ribosome synthesizes polypeptides (proteins). Organelles that involved in distribution and breakdown of molecules includes Golgi apparatus and lysosomes. Golgi apparatus transport and sort macromolecule and also form lysosomes (in animal)‚ where it serve as a recycling centers for animal cells. Finally‚ Mitochondria function in energy processing‚ where it covers chemical energy in food to energy of ATP. On the other hand‚ prokaryotic cells are

Ligand binding assays are an analytical procedure‚ whose method relies on the binding of specific ligand molecules to receptors‚ antibodies or other macromolecules (Hulme et al.‚ 2010). The analysis of radioligand binding assays are based on a simple model‚ called the law of mass action‚ which assumes that binding to the receptors are reversible. The binding to the receptors occurs when the ligand and the receptor collide by diffusion and when the collision has enough energy and the correct orientation

There are two types‚ DNA and RNA nucleotides – monomers that compose nucleic acid‚ consist of a pentose sugar‚ a phosphate group‚ and a nitrogen containing base.
