Since an animal only becomes more complex, and not simpler, an ancestor to all organisms would have to be the most simple and primitive organism.
I think that’s right thanks for the point god bless
Answer:
The restriction endonucleases in bacteria (b) they provide a defense mechanism against infection by viruses
Explanation:
The restriction endonucleases is a protein that is produced by the bacterias that interacts with the DNA of them and gives protection to the bacterial cell by defending against viruses.
Is important to remember that viruses go into different organisms just with a copy of DNA that wants to replicate inside of them creating more and more copies until it breaks the hosting cell and this is how the infection spreads. This protein restricts (that's the reason of its name) or stops the replication stage of the virus DNA by cutting it into many pieces stopping in this way the spread of the infection and the death of the bacteria.
Yes, but only if the chromosomes are paired in the right ways. tetrad development in late prophase.
<h3>How does DNA function? Why does it matter?</h3>
The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.
<h3>What is the purpose of a person's DNA?</h3>
Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.
