Answer:
Scientists might replicate a strand of DNA using PCR before sequencing it. Once the sequence is known, they can produce a corresponding gene probe
Explanation:
PCR refers to the polymerase chain reaction that amplifies the small sample of DNA into multiple copies in three steps. These steps are denaturation of sample DNA to produce single-stranded template strand, binding of primer to the template and elongation. The multiple copies of the sample DNA are then used to decipher its sequence using various sequencing methods.
Once the sequence of the sample DNA is known, the short, single-stranded DNA molecules that are complementary to the specific sequence of DNA are formed. These single-stranded DNA molecules are called DNA probe and are used to detect the specific nucleotide sequence in some other sample DNA.
Answer and Explanation:
D. Poultry
There are three important temperatures to remember when cooking meat or eggs at home: Eggs and all ground meats must be cooked to 160°F; poultry and fowl to 165°F; and fresh meat steaks, chops and roasts to 145°F.
Answer:
Emergence of an evolutionary adaptation
Explanation:
<h2>Answer:</h2>
Carbon moves from land to bodies of water as in following steps.
Carbon in the land is present in form of fossil fuels and plants and animals.
It converts into CO2 gas form by the burning of fossils and respiration of plants and animals.
This atmospheric CO2 is used by plants in water for photosynthesis.
Water bodies eat these plants for their nutrition. And use that carbon for making there carbohydrates, lipids and proteins.
Hence making land carbon their body part.
