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.
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.
they would have 3' and 5' at the same end
Normally, DNA forms a right-handed double helix but it can also come in other forms.

The sequence on the strand of the helix is TACCGGATC.
The DNA molecule is anti-parallel. This is because the two strands are the opposite of one another, such that if one strand has the base sequence ATC, the opposite strand would have the base sequence TAG.
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.

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
they would have 3' and 5' at the same end
