Explanation:
Answer:
adenine pairs with Thymine and guanine always pairs with cytosine respectively
Explanation:
In DNA nucleotide subunits, there are four nitrogenous bases:
- Adenine (A)
- Thymine (T)
- Cytosine (C)
- Guanine (G)
Each of these bases can be divided into two categories: purine bases and pyrimidine bases.
Adenine and guanine are examples of purine bases. This means their structure is a nitrogen-containing six atom ring joined with a nitrogen-containing five atom ring that share two atoms to combine the two rings.
Thymine and cytosine are examples of pyrimidine bases.
Note that RNA replaces thymine with a different pyrimidine base called uracil (U).
The complementary base pairing rule, Chargaff's rule states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.
Answer:
vAccording to one data set, the average American has has an ecological footprint over four times larger than the global average.
Answer:
The statement <u><em>'The National Institutes of Health says that acupuncture relieves pain and reduces nausea and vomiting, although it is unclear how it works' </em></u>supports that acupuncture relieves pain.
The National Institute of Health would have made the claim of acupuncture releasing pain by thoroughly testing it. Hence, this statement supports and lets the reader believe that acupuncture might be effective for relieving pain of the body along with other symptoms such as nausea and vomiting.
