A linear chain of proteins A circular array of nucleotides A double-stranded array of proteins A double-stranded array of sugar-phosphate groups linked together by bases None of the above View Feedback Question 19 4 4 points.

The three-dimensional structure of DNAthe double helixarises from the chemical and structural features of its two polynucleotide chains. Correct option is A The structure of tRNA can be decomposed into its primary structure its secondary structure and its tertiary structure - all tRNAs have a similar L-shaped 3D structure that allows them to fit into the P and A sites of the ribosome. Option number 3 that is DNA controls the production of proteins in the cell is the best relationship.

Examine the three dimensional structures of each of the following molecules in the simulation which can be found in the Real Molecules mode. A linear chain of proteins B. Adenine and thymine or between guanine and cytosine.

A double-stranded array of sugar-phosphate groups linked together by bases E. A DNA deoxyribonucleic acid molecule is made up of two strands complement each other means that the strands fit together and make bond with each other to establish as a double helix. Exploring the Molecule by Spinning and Zooming.

How are these solubilities consistent with the three-dimensional structure of double-stranded DNA. A linear chain of proteins B. Each type of protein has a unique sequence of amino acids.

It may be easier to visualize if you uncheck the box labeled Show Lone Pairs. A double-stranded array of proteins D. A double-stranded array of sugar-phosphate groups linked together by bases E.

A DNA molecule has which of the following 3-dimensional structures. Building on his work and the work of other scientists around the world the. Briefly Describe the 3-Dimensional Structure of DNA.

None of the above. A linear chain of proteins. Your answer is correct.

Because these two chains are held together by hydrogen bonding between the bases on the different strands all the bases are on the inside of the double helix and the sugar -phosphate backbones are on the outside see Figure 4-3. A linear chain of proteins B. The sequence of bases is read in a 5 3 direction so that you would read the structure in the next figure as ACGT.

The cloverleaf structure becomes the 3D L shaped structure through coaxial stacking of the helices which is a common RNA tertiary. This polymer is packed inside the nucleus of the cell by binding to sets of specific proteins called nucleosomes. If a protein molecule consists of more than one polypeptide it also has the quaternary structure which specifies the relative positions among the polypeptides subunits in a protein.
