What would happen without transcription?
If a gene is not transcribed in a cell, it can’t be used to make a protein in that cell.
If a gene does get transcribed, it is likely going to be used to make a protein (expressed).
In general, the more a gene is transcribed, the more protein that will be made..
Can RNA exist without DNA?
Based on this fact, almost all the biologists must think that there is no organism without DNA. However, it is possible that such an organism, especially a microorganism carrying RNA genome, exists on the Earth. … First, about half of the viruses have an RNA genome, either single stranded or double stranded (Flint et al.
What happens if Golgi apparatus is absent?
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn’t be able to live for very long.
What would life be like without cells?
These cells are the “building blocks” of life, and all have RNA or DNA in them and a membrane around the outside. … The only example of something “alive” without cells might be viruses (like what causes chicken pox or the flu) which are just packets of protein and DNA.
What will happen if man does not have DNA and only has RNA?
No, because DNA have coded information to produce proteins for various functions for the cell to do, so if there is no DNA then no one will remain to guide the protein synthesis in cells as a result the cell will eventually die.
Do we need DNA to live?
DNA Biological Functions. DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism’s or each cell’s development and reproduction and ultimately death.
Can you live without DNA?
Without DNA, living organisms could not grow. Further, plants could not divide by mitosis, and animals could not exchange genes through meiosis. Most cells simply wouldn’t be cells without DNA.
What would happen to the life of cell is there was no Golgi apparatus?
The golgi apparatus packages proteins into vesicles inside of the cell before sending them to their destinations. … The secretory activities of the cell would also cease to occur. Also, if there is no golgi apparatus, the plasma membrane would be affected because it needs to be able to grow larger for cell division.
Is RNA a life?
The RNA world is a hypothetical stage in the evolutionary history of life on Earth, in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. … Alternative chemical paths to life have been proposed, and RNA-based life may not have been the first life to exist.
Do humans have RNA?
Humans have four kinds of rRNAs. Transfer RNA, or tRNA, decodes the genetic information held in the mRNA and helps add amino acids to a growing protein chain. Scientists estimate that human cells have more than 500 different tRNAs.
Do viruses alive?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
What will happen if there is no cell?
With no cells, there are no tissues or organs. Humans would not exist. … Each purplish circle is a nucleus of a cell. The cells make up the kindey which keeps the human alive.
