Bacteria and other microbes can be used to "clean up" an oil spill by breaking down oil into carbon dioxide and water. Two sampl
Novay_Z [31]

Answer:

In sample A,  

The percentage of thymine or T is 20.5 %. A = T, so the percentage of A will also be 20.5 %.  

Thus, A + T = 20.5 + 20.5 = 41 %

Therefore, G + C = 100 - 41 = 59 %

So, G = 59 /2 = 29.5 %

Also. G = C = 29.5 %

In sample B,  

The percentage of Thymine or T is 30.7 %. As A = T, so A will also be 30.7 %.  

Thus, A + T = 30.7 + 30.7 = 61.4 %

Also, G + C = 100 - 61.4 = 38.6 %

So, G = 38.6 / 2 = 19.3 %

Therefore, C will also be 19.3 %. As GC content is more found in the sample A, that is, 59 %. Hence, the sample A will possess the higher temperature to denature in comparison to B.

Amanda gets protein at lunch by eating a chicken sandwich. How can Amanda’s body use the protein in the chicken to build protein
Ahat [919]

Answer:

- The proteins in the chicken are broken down into amino acids, and the DNA in Amanda's cells uses those amino acids to build human proteins.

Explanation:

The body uses the protein taken by Amanda in the form of a chicken sandwich by breaking it down into the form of compounds called 'amino acids.' Amino acids are described as the substances that are responsible for the formation of proteins in the body. Thus, the DNA present in Amanda's body cells will use these amino acids to form human proteins. The longer chains of these amino acids help the body to ensure its proper structuring and functioning.
