"Please write a response to each post from my classmates, base on the following discussion questions.
g:
o What are some of the benefits of squeezing so much data into virtually every cell in the body?
o Why did humans not evolve with one central repository of DNA rather than having it replicated throughout the body?
o Assume that the hereditary information carried in genes and DNA is responsible for many differences observed in humans and other living things. How could just four different bases in DNA strands be responsible for the almost endless variety found in nature?
Classmate1: The benefits of squeezing a lot of data into every cell of the body is that cells know when to split or how to split into different kinds of cells for tissue differences. They also know when to grow and when to stop growing for the maturity of the human body. DNA also knows when to replace tissue in case of injury to the body.
The slow reproduction of protein is one of the most important reasons why humans did not evolve with one central repository oppose to it being replicated. The chance of your meeting a wild animal in the woods, based on the reproduction of protein, would be slim to none. The production of protein would not be fast enough to inform your body to run. DNA is also required all the time and the body of a multi-cellular organism is a volume of single cells that have become specialized to performing different tasks.
Four different bases of DNA can be responsible for endless forms of nature because of the bases on how it unites in different ways to form information. A good example of this would be the numbers 0 - 9; ten digits that can form billions of sets of numbers in all sizes. Another example is the 26 letters in the alphabet that forms indefinite numbers of words.
Classmate2: DNA instructs our cells how and when they should divide and what types of cells they need to be. By having so much data in every cell, our cells know this information. The cells will know when to multiply and when to stop. Different DNA instructions can be deactivated within the cells and only the instructions that are needed for the formation of a particular type of cell will be activated.
Each cell in the human body uses its own DNA to make proteins for the cell to do its specific job. The DNA in each cell tells the cell what type of cells to become to form the different organs and tissues that make up humans and other living organisms. By having the DNA in every cell of the body, the cells know what needs to be done and when. DNA in every cell is responsible for the different traits seen in humans and other living organisms.
The combinations of the four different bases in DNA are endless, much like the combinations of the letters in the alphabet and the endless combinations of the numbers 0 and 1 in all computer data.
