Just as stated and also explained, the correct answer is <span>a long chain of adenine nucleotides is added to the 3' end of mRNA during terminationof transcription. That is the only statement that is true about the polyadenylation mechanism. Hope this is helpful</span>
Answer:
Collagen is an extracellular matrix protein and one of the most abundant protein in the body. Its triple-helical structure is a result of the 3 coiled chains. Each chain mainly comprises of Glycine, Proline and Hydroxyproline. The Glycine hydrogen bonds with residues of the adjacent chain while the proline and hydroxyproline C-N bonds provide stability in the structure.
Explanation:
Answer:
Active transport proteins use adenosine triphosphate (ATP), the cell's energy storage molecule, to pump glucose into the cell, either with or against the concentration gradient.

Isotonic because water is going both in and out of the cel
Explanation:
The plants would not retain their shapes.
Carbohydrates molecules that supply energy and provide support consist mainly of sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.
Many long chain polysaccharides are made up of glucose joined by regular 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.
It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass. When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.
