The strand of DNA that forms during replication complementary to the sequence 5' GGTTTCTTCAAGAGA 3' is 3' CCAAGAACTTCTCTC 5'. During DNA replication, the new strand is synthesized in the 5' to 3' direction, pairing adenine with thymine and cytosine with guanine. Therefore, the complementary strand would be built from the corresponding bases of the original strand.

How many strands are replicated in DNA replication?
During DNA replication, two strands of the double-stranded DNA molecule are unwound and each strand serves as a template for the synthesis of a new complementary strand, resulting in the formation of two new DNA molecules, each composed of one original strand and one newly synthesized strand.
During DNA replication DNA polymerase lands at origination sites and forms?
DNA polymerase is instrumental in DNA elongation as it catalyzes the addition of deoxyribonucleoside triphosphates to the 3 prime end hydroxyl group of the DNA chain. DNA polymerase binds on the origin of replication, and forms a pre-replication complex with other proteins. The replication complex unwinds DNA during replication
What type of DNA molecule forms as a result o DNA replication?
During DNA replication the two strands of the DNA helix split apart and the ribosome reads off the template strand producing an exact copy of this strand. Then RNA polymerase base pairs both of the strands, producing 2 semi-conservative strands.
Explain the function of replication?
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
When does a chromosome go from one chromatid to two sister chromatids?
A chromosome transitions from being one chromatid to two sister chromatids during the S phase of the cell cycle, specifically during DNA replication. This is when the DNA is duplicated, and each replicated DNA strand forms a sister chromatid with the original strand, creating a pair of identical chromatids joined at the centromere.
How many strands are replicated in DNA replication?

What happens at the DNA replication fork?
The DNA replication fork is where the replication origin forms the Y shape. The replication fork moves down the DNA strand to the strand's end, resulting in every replication fork having a twin.
Which of these show is the correct complementary strand of DNA that would be made during DNA replication based on this template strand ATCGGCTACGTACCTA?

Two new strands of DNA molecules grow as bases are added by the enzyme?
DNA polymerase during DNA replication. Each new strand is complementary to the original template strand and forms a double helix structure.

Do the two DNA double helices following DNA replication have the same or different composition?
After DNA replication, the two DNA double helices have the same composition as the original DNA molecule. Each new double helix consists of one original strand (the template strand) and one newly synthesized strand (the complementary strand). This ensures that the genetic information is faithfully preserved and passed on to the daughter cells.
If an incorrect nucleotide is incorporated into a fanning strand of DNA will this mistake lie transmitted to the next generation of DNA molecules that forms from this strand?
Yes, if an incorrect nucleotide is incorporated into one strand of DNA during replication, it will be present in the daughter strand and can be transmitted to subsequent generations of DNA molecules. This can lead to mutations and potential genetic disorders.
When does a chromosome go from one chromatid to two sister chromatids?
A chromosome transitions from being one chromatid to two sister chromatids during the S phase of the cell cycle, specifically during DNA replication. This is when the DNA is duplicated, and each replicated DNA strand forms a sister chromatid with the original strand, creating a pair of identical chromatids joined at the centromere.
How does DNA make more of itself?
Actually it doesn't. There are lots of proteins in the nucleus that do all the work. The beauty of DNA is that it acts as its own decoder (it forms a mirror image, but since a DNA strand consists of two mirror images the result is two copies).
What Replicates DNA by making a complementary copy of the original?
DNA replicates itself. What happens is, with the help of enzymes, the nitrogenous bases of DNA break away from each other, then copy themselves and re-attach. This process forms 2 strands of identical DNA.
