Answer: Option D) 1:4
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.
Then, 10% + 10% + C + G = 100%
20% + C + G = 100%
C + G = 100% - 20% = 80%
Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%
Ratio Adenine to Guanine is 10% to 40%
or 1:4 in simplest form
Answer:
C. Light intensity
Explanation:
they need light to grow so they stay near the ocean surface because that's where the most light is
Answer:
It is a single stranded DNA since adenine percentage is not equal to that of thymine and the percentage of guanine is not equal to cytosine.
Explanation:
According to Chargaff rule, the amount of adenine in a double-stranded DNA is always equal to that of thymine. This is due to the fact that adenine pairs with thymine in a double-stranded DNA. Likewise, the amount of guanine is always equal to that of cytosine in a double-stranded DNA.
The percentage of four types of bases in the genome of the virus does not follow the Chargaff rule and hence, it is a single-stranded DNA.
Because the target cells have the correct attachment for the hormone cells. For example, when you have a remote control you place the battery in the correct position to operate. Same way with hormones, they're wired to work with a certain type of cell because of how they work.
