How does the DNA in body cells compare? the DNA in body cells is the same, but cells use different parts of the DNA the DNA in all cells is different because different cells have different functions The DNA in body cells is different depending on the type of cell

Watch this video (http://openstaxcollege.org/l/DNArep) to learn about DNA replication. DNA replication proceeds simultaneously at several sites on the same molecule. What separates the base pair at the start of DNA replication?
Which best describes DNA polymerase? Group of answer choices an enzyme that removes the sugar molecule from a nucleotide so that the phosphate groups can be linked together an enzyme involved in DNA replication that binds to DNA and facilitates the formation of a new strand of DNA an enzyme that allows the chromosomes to coil around proteins so that the chromosomes can fit into the nucleus an enzyme that deletes specific regions of DNA an enzyme that breaks DNA down into fragments

Which statement most accurately describes the ‘backbone’ of DNA? Group of answer choices The DNA strand is wound up around histone groups which gives the backbone structure to the chromosome The sugar group from a nucleotide is connected to the next sugar group via a phosphate group The hydrogen bonds between nucleotides are quite strong and provide structure to DNA. Adenine and Thymine, and Guanine and Cytosine are linked together

In DNA replication new molecule is form different from previous only one strand is replicated both strands are replicated such that a new copy is composed of both new strands, and the original molecule is composed of both original strands both strands are replicated such that two molecules result, each having one old strand and one new strand
Reproduction of DNA Before DNA can copy itself the cell must make lots of extra A, T, G, and C. Then the DNA unzips between the two bases and adds nucleotides to each side of the unzipped DNA molecule. Original DNA Splits Open Adds New Nucleotides A- T-A= C-G T-A= -A= C-G= -%3D FA- -T Now, two DNA molecules exist where there was only one before. TION 1. Finish unzipping the DNA molecule pictured above, and draw the completed picture of the two “new" DNA molecules in the left margin. Use the same DNA sequences as the example above. 2. What are the two "new" DNA molecules built from? Explain. 3. Are the two "new" DNA molecules identical to the "original" DNA molecule? る。 TCAC TCAA UUUU UUD AÜ-C ACTT CGA JUUUO UDOUU
What happens to the RNA primers found in newly synthesized DNA? Their nucleotides are converted to deoxynucleotides by an enzyme They remain in the DNA They are removed by an enzyme and replaced with DNA
