DNA is in the shape of a:
A
single helix.
B
single circle.
C
double circle.
D
double helix.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand.

Detailed explanation-3: -DNA is most often found in the classic double helix shape. This is made up of two strands running in opposite directions. Each strand will have nucleotide bases sticking out of it-those famous letters of A, T, C, and G.

Detailed explanation-4: -DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

Detailed explanation-5: -Each DNA molecule is actually a pair of strands wound together, forming a double helix.
