When a cell does deviate from the norm, it may signal a malfunction: Skewed cell size is a hallmark of some diseases. Take small-cell carcinoma, a type of cancer that usually sprouts in the lungs, in which tumor cells are so puny that they barely have room for any cytoplasm.MITCH ...
What is a coding strand in DNA replication? DNA is the blueprint not only for the organism but for all the parts of the cell. How does DNA dictate the functions of a particular cell (by the production of proteins)? How does a cell produce proteins?
How Cells Work Proteins A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any protein. If you ignore the fat, your body is about 20-percent protein by weight. It is about 60-percent water. Most of the rest of your body is...

How does protein synthesis enable DNA to control the cell? Explain how mRNA contains information from a gene. What are the bases that make up DNA? Explain how DNA is used to generate proteins in prokaryotic and eukaryotic cells. What is the process of DNA sequencing?
This chapter will focus on cell signaling and signal transduction, that is, the extremely complex series of reactions by which cells receive and react to external signals (for reviews, see Hunter...doi:10.1007/978-3-642-55539-8_4Edmond H. Fischer...
Nearly one-third of all proteins in living beings are firmly embedded in abiomembrane—either in a cell's outer membrane or in the boundaries of internal cellular compartments. There, thesemembrane proteinsperform important tasks, serving, for instance, as molecular channels for transporting metabolite...
First, develop a balanced diet. As we know, the core of improving immunity is to enhance immune cells and immune molecules. Both two have a common feature. There is a high demand for proteins. And the source of the ...
How does protein metabolism occur? Protein: Proteins are macromolecules containing amino acids. It provides structural support to the cells and helps in catalyzing different reactions in its active form. Three types of proteins are observed in a human cell are globular, fibrous, and membrane proteins...
