If you mean forms as in shape, then spiral.
Yes. Our DNA has been passed on and changed/modified since the earliest forms of life.
The probe is the second strand of DNA that forms double-stranded DNA with the target gene.
neucleus is the site of DNA replication hence it forms DNA
The DNA molecule forms a double helix. The linear DNA chromosomes of eukaryotes form a highly supercoiled double helix.
Phosphates and Sugars formthe sides of the DNA ladder~
protein
Nucleic Acids
The sections of DNA called codons code for amino acids.
nitrogeous bases
A replication bubble.
Coiled up DNA, combined with protein histone, forms chromosomes.
Because DNA forms a double helix.
