What are free floating nucleotides?
transfer RNA, or tRNA Assuming this is the same this as free nucleotides (and it should be), they are nucleotides (the monomer of the polymer, DNA, made up of a phosphate, pentose sugar, and nitrogenous base) in the nucleus that are not attached to any strand of DNA or RNA, and thus literally "free floating" (i.e. floating in the nucleus not attached to anything and therefore "free")
What enzyme used to join the DNA strand that is replicated in small segments called?
DNA polymerase is what I think you are referring to. It will join free nucleotides into a strand based off of a model template.
Why does one DNA strand grow one nucleotide at a time and the other is assembled in short fragments?
The two strands of parental DNA separate, and each becomes a template for the assembly of a complementary strand from a supply of Why_does_one_DNA_strand_grow_one_nucleotide_at_a_time_and_the_other_is_assembled_in_short_fragmentsnucleotides. The nucleotides line up one at a time along the template strand in accordance with base pairing rules.

DNA replication of a leading strand involves which enzyme?
The enzymes involved in DNA replication are helicase, binding proteins, primer synthesizers, DNA polymerases and DNA ligases. The helicase unwinds the two nucleotide strands and the binding proteins stabilize the single stranded DNA. The DNA polymerases attach the free nucleotides to the growing strand and the DNA ligases seal the new short stretched of nucleotides into a continuous strand. If there are any errors in the process, the DNA polymerases, ligases, and others also proofread and repair any mix up in base pairs.
Do enzymes unwind the two strands of the parent DNA double helix during DNA replication?
Several enzymes participate in DNA replication, one being helicase which unwinds the two nucleotide strands.Binding proteins stabilize the single stranded DNA and DNA polymerase attach the free nucleotides to the growing strand. The DNA ligases seal the short stretches of nucleotides into one continuous strand
What enzyme assembles the complimentary nucleotide bases during replication?
THat would be the enzyme DNA Polymerase III which attaches free floating nucleotides to the parent strand. But remember, they can only be attached to a free 3' position!

What is the role of DNA polymearse?
Carries out DNA replication by moving down the leading strand and lagging strand ( two polymerase at once ) while reading the nucleotides and replicating them with free nucleotides that are in the cytosol. Some self correction mechanisms are on the polymerase itself in case of a misread.

What is the enzyme responsible for attaching free floating nucleotides to an open strand of DNA for replication?
Polymerase - in prokaryotes this is accomplished by pol III at the DNA fork. In eukaryotes this is performed by pol delta.
The direction of synthesis of an RNA transcript is?
transcription:"the first step in protein synthesis, a sequence of nucleotide bases becomes exposed in an unwound region of a DNA strand. That sequence acts as a template upon which a single strand of RNA - a transcript - is synthesized from free nucleotides."The synthesis of an RNA molecule from the DNA template strand is called transcription.
How do polymerase create new strands of DNA?
DNA helicase is the main enzyme responsible for splitting the two strands of DNA (or 'unzipping' the DNA). This allows DNA polymerase to come along and copy the DNA, by joining free nucleotides (A, T, C, G) to the template strand of DNA. This is how a new strand of DNA is created.
How does DNA divide?
The division of DNA is called replication.The two strands of DNA are separated with the help of an enzyme, helicase. Each strand of DNA then "grows" a new strand along its length. The new strands are formed from free (uncombined) nucleotides. These nucleotides obey the rules of base pairing, so where the old strand has an A (adenine), the nucleotide that moves into position opposite it in the new strand has a T (thymine). Likewise C (cytosine) pairs with G (guanine).Each old strand is described as acting as a template for the formation of the new one.The nucleotides of the new strands are "stitched together" by enzymes called DNA polymerases.DNA replication is called semi-conservative, because each resulting molecule of DNA has one old strand and one new one.For more information, for example on the roles of the different DNA polymerases, and on such niceties as lagging strands and Okazaki fragments, use the links below.
Who are copies of DNA made and need a picture of it to?
DNA is copied in a process called DNA replication. During DNA replication, the two strands of the DNA molecule separate. Then free DNA nucleotides pair with their complimentary nucleotides according to the base-pairing rule on each of the old strands of DNA. Once the process is complete, the result is two identical DNA molecules, each with one old strand of DNA and one new strand of DNA. Refer to the related link for an illustration.
