BioBeyond - Genetic Blueprints Questions
and Answers| Latest Update
What parts of the nucleotides you built connect to each other to form the chain? Sugar
Phosphate
What repeating unit forms the chain connecting the nucleotides? Phosphate-Sugar
Which details became clear about DNA from Photo 51? The sugar-phosphate backbone is
on the outside.
The radius of DNA is 1 nanometer
What was Rosalind Franklin's contribution to the discovery of the structure of DNA?
Wilkins showed Franklin's data to Watson and Crick without her knowledge, allowing
them to deduce a double helical structure
What were the key new features of Watson and Crick's model? Specific base pairing
Bases on the inside
Which nucleotides bond with each other to give the DNA molecule the correct radius? Select all
that apply: A and T
C and G
, Which part of the nucleotides you built connects the two strands? base
Choose the letter of the correct schematic.Top to bottom S
A
P
What color is the backbone? orange
What color are the bases? purple
DNA isn't the only nucleic acid used by biological organisms. Organisms also use a similar
nucleic acid, ribonucleic acid or RNA, for several cellular processes.
Shown to the right are schematics of an RNA nucleotide and DNA nucleotide.
What differences do you see? Select all that apply: the sugar is different
Nucleic acids aren't just the realm of biological chemistry. Experiments by a Swiss scientist,
Albert Eschenmoser, on nucleic acids in the 20th century yielded an interesting result: threose
nucleic acid, or TNA. TNA is a synthetic (man-made) nucleic acid that acts just like natural
nucleic acids, but resists enzymes that normally would break down nucleic acids.
Diagrams of TNA and RNA are shown to the right.
