Answer:
Adenine= 22%
Guanine= 28%
Cytosine = 28%
Explanation:
According to Chargaff rule, the amount of adenine in a double-stranded DNA is equal to the amount of thymine. This is due to the fact that adenine and thymine bases are complementary and form base pairs.
Likewise, the amount of guanine in a double-stranded DNA is equal to the amount of cytosine since guanine pairs with cytosine.
Given that percentage of thymine in a DNA sample = 22%
Percentage of adenine = 22%
Total percentage of adenine and thymine = 22+ 22 = 44%
Percentage total of guanine and cytosine bases = 100-44 = 56%
Percentage of guanine base in the DNA = 56 /2 = 28%
Percentage of cytosine base in the DNA = 28%
Often a plasmid is used in recombinant cloning technology to clone newly isolated genes. It is also very common to use a recombinant plasmid to express large amounts of a known gene to obtain RNA or protein from it. Such recombinant gene expression has been indispensable for the biotechnology industry.
The preoperational stage is the second stage in Piaget's
theory of cognitive development. Children begin to take part in symbolic play and
learn to manipulate symbols throughout this stage. This stage begins around age
2, as children start to talk, and lasts until around age 7. The answer is that Piaget’s
explain that Preschool children's tendency headed for centration avoids them
from focusing on other applicable features of a situation.
Phylogenetic is also called the evolutionary tree, it is a branching that shows the relationships among various biological organisms based on their similarities and differences in the genetic and physical traits. Chloroplast is an organelle found in all photosynthetic plants as its key in the process of photosynthesis . If the chloroplast of wheat is sequenced it would appear at the base of plantae ( a kingdom containing all eukaryotic, multicellular, photosynthetic plants)
Answer:
40%
Explanation:
Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.
If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.
The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.
Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.
