what is the peculiarity of the ‘dna’ structure?
peculiarities of the dna structure: dna is a double helical structure having nucleotides. these nucleotides are made of deoxyribose sugar, phosphoric acid and nitrogenous bases such as adenine, thymine, cytosine and guanine. the nucleotide sequence of the dna molecule is called a gene. genes are present on dna. a type of gene is responsible for the synthesis of a particular protein. changes in the gene can alter the characteristics of the organisms.
length of dna sequence yeah, its an incomplete genetic code, having only half the required chromosomes needed to create a life. it also doesn't consume food and produce waste, it cannot itself reproduce, etc. its clearly and obviously, as long as your not an anti science person, not a human being but a fetus is (again so long as your not anti-science). the process through which dna creates its own copies is known as
dna replication


at first, dna double helix starts unwinding in several points these
points are known as origin of replication

enzyme helicase helps in the process of unwinding by breaking the
h- bonds of the paired nucleotides to break apart the two templates
of dna

by the action of enzyme primase, a small primer
which is a small chain of rna by polymerization is formed on the
template at the point of origin of
replication

after unwinding up to a certain point, dna represents a y
â€“ shaped replication fork

the enzyme dna polymerase starts supplying
nucleotides that are complementary to the nucleotides of the dna
template in 5â€™ â€“
3â€™ direction

the synthesis of new strand will be in opposite direction as both
the strands run in antiparallel manner

the new strand that is formed on 3â€™
â€“ 5â€™ strand of template dna
is a continuous strand in 5â€™
â€“ 3â€™ direction and is known
as leading strand however the strand that is
formed on the other template of double helix are formed in
fragments and called lagging strand the small
fragments are called okazaki fragment

the fragments are joined by the joining enzyme called
ligase

during replication, dna polymerase automatically goes back to the
point of the strand where wrong base is formed and corrects it
(proof reading) before proceeding to further
replication
