Label the figure below. Word bank: leading strand, lagging strand, DNA
Natalija [7]

Answer:

DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.

Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.

The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.

The points where DNA is currently unwinding are called replication forks.

A new born has soft spot on he top of its head. This is called as fontanelle and is diamond in shape present on the top of the head of the baby.

Babies skull is very soft and can be very easily moulded, to help them squeeze through the birth canal at the time of delivery.

Moulding is done in the skull of the babies as it is most largest part of the body during the time of delivery.

As soon as the skull and bones of the baby meet and fuse they become hard gradually.
