Concept explainers
(a)
Interpretation: The validation of the given statement that DNA is a double stranded molecule and RNA is a single-stranded molecule has to be stated.
Concept introduction: The process by which generation of new proteins in a cell takes place is known as protein synthesis. It consists of two stages, that is, transcription and translation. DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.
(b)
Interpretation: The validation of the given statement that RNA and DNA molecules have about the same length has to be stated.
Concept introduction: The process by which generation of new proteins in a cell takes place is known as protein synthesis. It consists of two stages, that is, transcription and translation. DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.
(c)
Interpretation: The validation of the given statement that base pairing occurs in both DNA and RNA has to be stated.
Concept introduction: The process by which generation of new proteins in a cell takes place is known as protein synthesis. It consists of two phases, that is, transcription and translation. DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.
(d)
Interpretation: The validation of the given statement that DNA and RNA have the same sugar unit present in their structural backbones has to be stated.
Concept introduction: The process by which generation of new proteins in a cell takes place is known as protein synthesis. It consists of two stages, that is, transcription and translation. DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.

- SH 0arrow_forward2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2arrow_forwardNonearrow_forward

Is this structure a meso compound? d. Please consider the natural product alkaloids shown below. Are these two structures enantiomers, diastereomers or conformers? H HO H H HN HO HN R R с R=H cinchonidine R=ET cinchonine Harrow_forwardNail polish remover containing acetone was spilled in a room 5.23 m × 3.28 m × 2.76 m. Measurements indicated that 2,250 mg of acetone evaporated. Calculate the acetone concentration in micrograms per cubic meter.arrow_forwardPlease help me answer number 1. 1. If your graphs revealed a mathematical relationship between specific heat and atomic mass, write down an equation for the relationship. I also don't understand, is the equation from the line regression the one that I'm suppose use to show the relationship? If so could you work it all the way out?arrow_forward
- Describe the principle of resonance and give a set of Lewis Structures to illustrate your explanation.arrow_forwardDon't used hand raitingarrow_forwardIt is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO interacting with anti-bonding MO...]arrow_forward
