SVETLANKA909090 [29]

Answer:

Sample A

T= 21.3% and A= 21.3%

G=28.7% and C= 28.7%

SAMPLE B

T=28.7% and  A= 28.7%

G= 21.3% and C= 21.3%

Sample A would have higher melting temperature

Explanation:

According to given information, sample A contains 21.3% thymine.

Percentage of adenine in sample A= 21.3% (Since adenine base pairs with thymine, so, adenine and thymine are present in equal amount in a double stranded DNA)

Total of A+T in sample A= 21.3 + 21.3 = 42.6%

G+ C content of sample A= 100-42.6= 57.4%

Percent G content of sample A = 57.4/2 = 28.7%

Percent C content of sample A = 28.7%

SAMPLE B:

According to the given information, sample B contains 28.7% thymine.

Therefore, percent of Adenine base in sample B= 28.7%

Total of A+T content in sample B= 28.7 + 28.7 = 57.4%

G + C content of the sample B = 100-57.4= 42.6%

Percent G content of the sample B= 42.6/2= 21.3%

Percent C content of sample B = 21.3%

There are three hydrogen bonds between a GC pair while there are only two hydrogen bonds between AT pair. The DNA content with higher GC content has higher melting temperature. Therefore, sample A would have higher melting temperature.

Explain how scientific theories differ from scientific laws.
Sunny_sXe [5.5K]
<h2><em>In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research</em></h2>

OLga [1]
C. Temperature and pH can affect how enzymes work

Enzymes show a maximum activity at an optimum pH and temperature. Changes in the pH or the temperature can cause damage in the structure of the enzymes, if the structure changes the substrate can no longer bind to the enzyme, which is why the activity of the enzymes starts to slow down.
