This is Dolly, the first sheep produced using a novel type of molecular genetic technology that involved transfer of the nucleus from an adult udder cell to an unfertilized egg whose nucleus had been removed. This egg was then transplanted into another female sheep to undergo development during pregnancy.
Sheep, as well as humans, normally begin life as a single cell called a fertilized egg or zygote. From this one cell, trillions of cells will ultimately be derived through the process of cell division. Prior to each cell division event, the DNA must replicate. Also, cells must produce proteins needed to accomplish specific functions. These events are described by the central dogma of molecular biology, which states that DNA contains information to replicate itself and that specific regions of the DNA (called genes) contains the information needed to make RNA, which is in turn used to produce needed proteins. In this chapter, we will learn more about the steps of these processes.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
