Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
Answer:
Nucleotide ( monomer )
Explained Definition:
The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids
1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.
3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products
4. polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group
Answer: The shell of the giant African snail reaches up to 7.8 inches in length and 2.7-3.9 inches in height. An adult weighs about 32 grams. The body has two short tentacles and two long ones that have the eyes. The shell has an appearance conical and narrow, with 7 to 9 spirals visible on its surface.

Answer:
To keep blood safe, blood banks carefully screen donated blood. The risk of catching a virus from a blood transfusion is low. Sometimes it is possible to have a transfusion of your own blood. During surgery, you may need a blood transfusion because of blood loss.
hope this helps!!:)
