During what stage of the cell cycle does the cell grow and carry out it regular functions? a. Mitosis. b. S. c. G1. d. G2. Mitosis occurs in what type of cells? (somatic or germ or both) What process is called "one cell division", meiosis or mitosis?
In this lesson we'll go over what cell division is in different types of cells and look at the factors that stop cells from dividing. We'll also learn what happens when cell division doesn't stop. What Is Cell Division? All life starts with a single cell. That cell multiplies as we...
The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In eukaryotic cells, DNA replication occurs during the S-phase of the cell cycle. During S-phase, RNA transcription and protein translation are largely limited to the ...
Essentially, back titration is a titration done in reverse. The person performing the titration does not titrate the original sample; instead, they add a known excess of standard reagent to the solution, with the excess then being titrated. Back titrations are useful if the reaction between the...
Particularly in metal-film type devices where the electrodes are only a few dozen nanometers thick to start with, it takes very little corrosion to cause problems. Additionally, high-vibration environments can also be troublesome by causing mechanical failure of device leads, attachment between leads...
Static random access memory (SRAM).This type of RAM is typically used for the system's high speed cache, such as L1 or L2. Like DRAM, SRAM also needs constant power to hold on to data, but it doesn't need to be continually refreshed the way DRAM does. SRAM is more expensive than...
