I is correct and II is incorrect Characteristics of life include: growth and metabolism Examples of synthetic substances are: plastics and silicones Examples of organic biological substances are: carbohydrates and fats Examples of mineral substances are: paraffins and petroleum Matter is everything that: occupies space and has weight The ...

Central Dogma - correct answerDNA-(Transcription) - RNA- (Translation) -Protein DNA Structure - correct answer1. Deoxyribose: 5 Carbon atoms are numbered 1' to 5' . Hydrogen attached to 2'. Sugar 2. Phosphate group Sugar-Phosphate backbone is asymmetric because PO4 groups connect the C5' of a sugar with the C3' of neighbouring sugar. = Asymmetric ends because the C5' end is attached to a PO4 and the C3' end is simply a hydroxyl group of the sugar. 3. Nucleic Acid: No-covalently bonded to ...

Monosaccharide formula correct answer: (CH2O)n (n is 3 or more) Aldotriose correct answer: Also known as glyceraldehyde, simplest aldehyde monosaccharide (n = 3), has L and D isomer (centre carbon is chiral) Ketotriose correct answer: Also known as dihydroxyacetone, simplest ketone monosaccharide (n = 3), non chiral Carbon numbering correct answer: Aldoses always have aldehyde and C1, ketoses have ketone at C2 Sugar naming correct answer: triose, tetrose, pentose, hexose, etc., ...

Glycine Glycine is the most simple amino acid - its best to just memorize that this important amino acid has a functional group that only contains a hydrogen! Alanine Alanine has a really simple functional group (just a simple methyl group) that some of the other AA functional groups build on. You can remember the name because the alphabet builds on the letter A and other functional groups build on the simple Alanine R group. What about the other A amino acids? well Alanine has the shor...

Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energy...

Chem 219 Unit 5 Exam with Correct Solutions Generic formula for alcohols - Answer -R-OH phenol - Answer -hydroxy-substituted aromatic molecules (any compound with an -OH attached to a benzene ring) IUPAC system rules for naming organic alcohols - Answer -- organic alcohols are named by replacing the suffix of the parent chain of the molecule with the suffix -ol - The parent chain is numbered so as to give the hydroxyl group the lowest possible number. (examples: 1-propanol, and cyclohexan...

Monosaccharides - correct answer __________ are the simplest Carbohydrates Carbohydrates are aldoses or ketoses that are rich in hydroxyl groups. - correct answer Carbohydrates are _________ or ________ that are rich in ___________. An aldose is a carbohydrate with an aldehyde group (as in glyceraldehyde and glucose), whereas a ketose contains a keto group (as in dihydroxyacetone and fructose). - correct answer What is an Aldose? What is a ketose? if the absolute configuration of ...

agarose and agar correct answer: polysaccharides used to run DNA gels and for microbial plates bacterial cell walls correct answer: contain polysaccharides in their peptidoglycan layer lectins correct answer: are proteins that bind to sugars protein glycolsylation correct answer: assists in folding and cellular recognition, e.g. ABO blood groups -ose correct answer: indicates a molecule is some kind of carb blood group antigens correct answer: glycoproteins containing differ...

What is the formula for a monosaccharide? Use an example to describe how monosaccharides link to form disaccharides correct answer: (CH2O)*n, where n is the number of carbons and must be greater than 3 (e.g. glucose has 6 carbons, C6H12O6). Glucose and fructose are both monosaccharides, which link through a glycosidic bond to form sucrose, a disaccharide Name, classify and describe the two simplest monosaccharides (3 carbons) correct answer: Glyceraldehyde: Aldo-triose, aldehyde on one end ...
