The meaning of this is to try and give you a visual of the double helix, because if you have ever seen and winding staircase you should have seen that the stair case had steps well in this case the steps represents the linked nucleotides.
The coiled structure of double-stranded DNA in which strands linked by hydrogen bonds form a spiral configuration, with the two strands oriented in opposite directions.
yes
A spiral staircase is actually a very good analogy for DNA. The railings are like the chains of Deoxyribose (the type of sugar that gives DNA its name) that give the DNA molecule its shape. The steps in the staircase would represent the base pairs (made up of Adenine, Guanine, Thymine, and Cytosine) that contain the genetic information.
They are helical in their structure; they look like a strand of DNA (the double helix.)
Its structure is two spirals interlaced; double meaning two, helix being the technical word for such a shape. DNA is known as the double helix because it coils up into chromosomes and looks like a winding staircase.
we dont know what the first sentence is!!
The coiled structure of double-stranded DNA in which strands linked by hydrogen bonds form a spiral configuration, with the two strands oriented in opposite directions.
Watson and Crick DNA model was shape like a winding staircase
That DNA molecule is a double helix-two strands twisted around each other, like a winding staircase
Inclined plane
A Dutch boxed staircase is a staircase that has enclosed sides, creating a box-like structure around the stairs. This design is common in Dutch architecture and provides a classic and elegant look to the staircase.
This phrase typically means that the road was winding and unpredictable, much like the path a gypsy might take while traveling. It conveys a sense of unpredictability and adventure.
A staircase descender is a chair (like a wheelchair) that has a flat back. The flat back can be pulled down to lay flat (like a stretcher) and the ambulance team can take a person from one level to the next by sliding the descender. Sydney Staircase Builders
A staircase is more like a stepped slope.
Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.
