Does DNA replication take place in the same direction along both strands of the DNA molecule that is being replicated?

Yes. If it cut short, then one copy would be incomplete. But through mitosis or meiosis, either one, the entire set of DNA is replicated fully.

Compare the leading and lagging strands during replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
What is the process by which a DNA molecule is copied called?
dna replication. can be summarised as the two helical strands of dna unravelling through the action of enzymes and the corresponding nitrogenous bases of each being matched up (A-T, C-G) to form two identical strands
Why is replication on one strand of DNA continuous while on the other strand the replication must be discontinuous?
New strands of DNA can only be created in one direction - 5' to 3'. This is because only the 3' end of the DNA is able to join to a new nucleotide. The two strands of DNA are antiparallel - meaning they run in different directions. Therefore only one strand (called the leading strand) is running in the correct direction for continuous replication. The other strand (called the lagging strand) must first be looped around so that small sections can be replicated in the correct direction.
DNA replication involves producing new copies of DNA molecules. How many individual DNA strands exist after one molecule of DNA has been replicated?
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
How many copies of DNA molecule result from two replication of a single DNA molecule?
Four.
What is birectional replication in DNA?
A DNA molecule has two complementary strands, the top (leading) one is 5' to 3' and the bottom (lagging) one is 3' to 5'. The 5' carbon has a phosphate group linked to it and the 3' carbon has a hydroxyl group. During replication, both strands get replicated however DNA strands due to their molecular structure can only be replicated from 5' to 3' so the lagging strand is replicated in 5' to 3' pieces called Okazaki fragments. However, even with this, replication still happens in both strands, even if in the same direction (5' to 3').
How many strands are replicated in DNA replication?
Two - the leading strand and the lagging strand.
Where does replication of the two DNA strands takes place?
in a direction opposite to that of the replication fork
Compare the leading and lagging strands during replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
How many individual DNA strands exists after one molecule of DNA has been replicated?
4
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
What is a y-shahped point that results when the two strands of a DNA doble helix separate so that the DNA moecule can be replicated?
Replication Fork
Is DNA replication conservative or semi conservative?
Semi conservative. The double strand splits into two strands and then a strand is replicated from the template of the two strands constructing four total strands. Two original and two copies.

Is RNA polymerase used in both leading and lagging strands of DNA replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
