The ability to reproduce in kind is a basic characteristic of all living things. In kind means that the offspring of any organism closely resemble their parent or parents. Hippopotamuses give birth to hippopotamus calves, Joshua trees produce seeds from which Joshua tree seedlings emerge, and adult flamingos lay eggs that hatch into flamingo chicks. In kind does not generally mean exactly the same. Whereas many unicellular organisms and a few multicellular organisms can produce genetically i...

Preparation of the correct buffer is key to any good biological experiment and it is important that you understand how to calculate the mass of each chemical required to make that buffer and what the resulting concentration of those constituents will be in moles per litre.

Phosphate Buffered Saline (PBS) is a commonly used buffer for experiments in biology because its pH and ion concentrations are similar to those in mammalian organisms. It works in a similar fashion to the blood plasma buffer mentioned in the textbook, but using dihydrogen phosphate ions and hydrogen phosphate ions for buffering through the following chemical reaction: H2PO4- (aq) ⇆ H+ (aq) + HPO42--(aq)

In short it simply means protein synthesis which includes and happens in cells of all living organism. To start with the derivation of protein from the cell hence DNA comprises of two processes or stages. These processes are transcription and translation. Transcription in a typical eukaryotic cell occurs in the cell nucleus. During this period DNA is used as a template to create a molecule of messenger RNA (mRNA) where it leaves the nucleus and move to a ribosome found in the cytoplasm for trans...
