Bio 4.1.2 by Jade Shepherd
Summarize the relationship among DNA, proteins, and amino acids in carrying out the work of cells and how this is similar in all organisms.
From DNA to a Protein
The image above shows the process of protein transcription. In the image, it shows DNA in the original stage. From there, the DNA is replicated. Then, it is replicated and Thymine is then replaced with Uracil. Now the pairs are A to U and G to C. This is now called RNA. This strand is place into groups of three, otherwise known as codons. Codons are then translated into amino acids, the base of proteins. There are specific amino acids for a group of proteins. You can see examples of this below.
An example of how to read this chart:
- Pick your codon
- AUG
- Look on the vertical column for the first letter, A
- You should now only be looking at the third row down.
- Do the same thing for the second letter but, this time you are looking at the top to find the second letter
- U is the first column
- Now, only looking at the third row and first column, find your last letter, G
- The amino acid you are looking for is Met
Could We Survive Without Proteins?
There is a definite answer to this question. No, there is no way we could every make it a single day without proteins, amino acids, and DNA. The same process happens in every living organism because we all need these specific proteins for our bodies to function and our cells to differentiate.
