DNA is linear, so there must be two ends to it. (Prokaryote circular genomes have a 5' and 3' end as well, but only for directional purposes).
DNA grows from 5' to 3'
Double helix
three different roles in DNA polymerase are 1. binding of enzymes to existing DNA 2. Unwinding of the double helix 3. Synthesis of a new matching strand for each existing strand
The sequence on the strand of the helix is TACCGGATC.
they would have 3' and 5' at the same end
1. DNA unzips 2. Nitrogen bonds floating outside of the nucleus attach with the unzipped DNA. 3. Two DNA strands with the exact same bases are formed.

The DNA structure is called a double helix. It consists of two strands that are twisted around each other, resembling a twisted ladder.
The sequence on the strand of the helix is TACCGGATC.
DNA has two polynucleotide molecules that spiral around an imaginary axis to form a double helix. only certain bases in the double helix are compatible with each other. Adenine pairs with thymine and guanine pairs with cytosine.

Antiparallel base pairing refers to the arrangement of nucleotide bases in DNA strands that run in opposite directions. In this arrangement, the 5' end of one strand is paired with the 3' end of the complementary strand. This allows for the formation of stable hydrogen bonds between the bases to maintain the structure of the DNA double helix.
Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .
here are some characteristics: 1. The Double Helix Structure 2. The Ladder Shape 3. The Twisted Form
