|
|
The double helix shows that one strand of the DNA ladder is inherited from each parent.
|
|
|
The sugars and phosphates that make up the sides of teh DNA ladder twist and curve to conserve space in the cell.
|
|
|
The double helix is a random occcurance and DNA could just as easily be a straight single-stranded molecule
|
|
|
The pattern of complementary bases on each side of the DNA ladder ensures that exact copies of the DNA are made during replication.

Detailed explanation-1: -Watson and Crick proposed the molecular structure of DNA which they termed the “double helix”. The specific pairing of nucleotides is a key feature of the Watson and Crick model of DNA. Here, each DNA strand is linear and long, comprising smaller units known as nucleotides which in turn form a chain.
Detailed explanation-2: -Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.
Detailed explanation-3: -Double helix, as related to genomics, is a term used to describe the physical structure of DNA. A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
