A double helix of dna is formed when two dna strands each having a 5' and a 3' end wind around each other <span />
Answer:
The correct answer will be option- deoxyribose, thymine, and a phosphate group.
Explanation:
Deoxyribose nucleic acid or DNA is a type of nucleic acid which acts as genetic material in the organisms.
Each strand of DNA is made up of nucleotide which is made up of a 5 carbon sugar called deoxyribose, a phosphate group and 4 types of nitrogenous bases mainly adenine, thymine, guanine and cytosine. The sugar and phosphate form the backbone of the DNA molecule while the nitrogenous bases are stacked perpendicular to the backbone.
Thus, option- deoxyribose, thymine, and a phosphate group.
Such deterioration allows large amounts of ultraviolet B rays to reach Earth, which can cause skin cancer and cataracts in humans and harm animals as well.
<span>To
protect plant form insect damage, I will make it into a transgenic plant. Transgenic
plant are called genetically modified organisms (GMO) because there is a gene
added or removed in the original plant to obtain a set of characteristic such
as insect damage.</span>
Agriculture just became easier. It was much easier and safer than directly hunting, albeit, it wasn’t always as rewarding, but it was much more reliable. If you could hold off until the large crop was fully grown with hunting, you could rely on the large crop while waiting for the next one, and have a berth large growth. In other words, it was more reliable, easier, and could be very lucrative.
