Question
Hey, i understand that i am only suppose to upload one question at a time but i really need your guys help. I did horrible on my BIO-2 test and I need to know what i did wrong becuase this material is going to be on the final test so I need to know what i did wrong. Please help me with these multiple choice questions. Please answer all of them i would really appreciate it! Thank you so much for your time and help!
ome translating the protein E. the exact nature of the ribos . Which of the following statement A t is found as a double straneout DNA is false statements about DNA is false: e stranded molecule molecule he phosphate and the deoxyri olecules ribose sugars form the outer he phosphate and the deoxu backbone o one of the DNA molecul C. The two strands run in the same 5to 3 D. DNA is used to store genetic information in a living organism s run in the same 5' to 3' orientation E. Each strand of DNA is used as a template for replication 17. Which bond is illustrated below: bond OH CH2 CH2 N-C A. 1, 4 glycosidic bond in cellulose B. phosphodiester bond C. 1,4 glycosidic bond in cellulose D. Dilipid bond in fatty acids E. Peptide bond in proteins 18. Which of the following CORRECTLY describes cholesterol? A. It is a monomer used to make a polymer. B. Its function is to store energy. C. It helps cushion vital organs and provides insulation in mammals. D. It is composed of a carboxyl group attached to a long hydrocarbon chain E. It is the molecule from which estrogen and vitamin D are derived.Explanation / Answer
16) DNA is a double stranded helical structure. It contains genetic information about the organism. During replication, both the strands act as templates for the generation of new strand. One strand runs from 5'-3' end and the other strand runs from 3'-5' end. Therefore, the answer for this question is option C (two strands run in the same 5'-3' orientation).
17) Peptide bonds in proteins are represented in the picture. It is formed by reaction between amino group of the amino acid with carboxyl group of the previous amino acid.
18) Cholesterol stores energy. It helps to cushion vitsl orgsns and provide insulation in mammals. Estrogen and vitamin D are produced from cholesterol. (options B, C, E)
19) The polymer whose primary function is storage is starch.
