Chromosomes are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contains man...
What are proteins in biology? Where are the proteins for a cell made? What do ribosomes produce? What does the nucleus do in protein synthesis? What proteins come packaged in HIV cells? What is used to direct protein synthesis in the cell?
In DNA replication E.coli, what enzymes are more active on the lagging strand than on the leading strand? What types of proteins can associate with DNA to form "chromatin"? What is RNA Polymerase? How does it help protein synthesis?
46.Which type of RNA copies DNA's instructions in the nucleus? 47.Which type of RNA is most abundant? 48.What does tRNA transport? 49.What2things make up ribosomes? 50.Define transcription. 51.In what part of a c...
Membrane proteins are proteins that are embedded among the phospholipids that make up the bilayer structure of cell membranes. The membrane protein performs specific tasks that are essential for the proper functioning of the cell. These include transporting molecules and ions into and out of the cell...
Question: What cell/protein of the immune system is being described? These cells secrete antibodies (2 possible answers). Adaptive Immunity: Adaptive immunity is a term that describes the specific immune system which deals with specific invading pathogens including bacter...
Proteins are a second type of intracellular organic molecule. These substances are made from chains of smaller molecules called amino acids, and they serve a variety of functions in the cell, both catalytic and structural. For example, proteins called enzymes convert cellular molecules (whether prote...
Sometimes the process of protein synthesis involves additional steps after the polypeptide has been created. Proteins can begin to fold into their native structure, or most stable three-dimensional conformation, with hydrophobic interactions. Since the cell is an aqueous, or water-based, environment, ...
