What does it mean to say DNA polymerase reads a template strand to make the complementary strand?
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.
An old DNA strand is used as a for the assembly of a new DNA strand?
the process is called semi-conservative because it's half old and half new
DNA replication is semi-conservative. What does this mean?
When DNA is replicated, the new double-strand contains one old strand and one new strand. This means that one of the old strands has been conserved, making DNA replication semi-conservative.
What is the new strand called in Dna replication?
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
What is the new strand complementary to the old strand?
DNA strands are said to be complementary because they both match up with eachother; A with T and C with G. So if you have the strand ATGGCTA the complementary strand (the other half of the double helix) would read TACCGAT. So if you know one side of the strand then you can describe the whole.
The sequence of bases in DNA determines the sequence of what?
When a new DNA is formed , two strands of old DNA open and act as a template for synthesis of two new strands of DNA .Sequence of bases in new strand of DNA is determined by old strand and it is based on complementarity i.e. A pairs with T and G Pairs with C .

What determines the nitrogen base sequence of a DNA in a new strand of DNA?
Since A pairs with T, and G pairs with C, then the sequence of bases in the strand of DNA being copied determines the sequence of bases in the newly copied strand. The bases are complementary (A gives T and G gives C when copied).
What base sequence would be produced through DNA replication?
DNA replication is a semi-conservative process. The DNA is split into two strands. Nucleotides are then attached to each strand by complementary base pairing, where A attaches to T and G attaches to C. The newly formed strand is hence identical to the old strand and the base sequence of DNA can hence be conserved during replication.
What does semi conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
DNA is a macromolecule that is shaped like a double?
Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.

What is the role of DNA polymerese in DNA replecation?
to add complementary nucleotide respect to the old strand for new strand synthesis.....

What does semi-conservative model mean?
Refers to semi-conservative replication of DNA. One strand of the old DNA is used as a template to replicate the other, new, strand of DNA. Thus you have four from two, but two of the four are old strands while the other two strands are new. Thus the name semi-conservative replication.
What is the difference of old and a new strand of DNA?
old is broken but new is not
What is the new strand called in Dna replication?
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
