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 is the leading strand considered continuous?
The leading strand is the correct orientation, so it can be replicated continuosly - meaning the DNA Polymerase can continue to add new nucleotides without stopping. New DNA strands can only be created in a 5' to 3' direction. This is different to the lagging strand - which must be looped and copied in small, non-continuos segments. These segments are known as Okazaki fragments.
What is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?
RNA Polymerase
What are the short segments produced in the formation of the 3'-5' strand of DNA called?
During DNA replication, the lagging strand is replicated ~1000 (E. coli) base pairs at a time, forming numerous "Okazaki fragments".Okazaki fragments form because polymerase is only able to replicate DNA in one direction, but DNA is double stranded, with the strands running anti parallel (in opposite directions). The polymerase waits for a region of DNA to be unwound, and while the leading strand is replicated continuously, on the lagging strand the polymerase waits until a region of single stranded DNA is produced before replicating it. This discontinous replication forms the Okazaki fragments, which can then be joined together by ligase (although a different polymerase enzyme, pol I in E. coli, is needed as well to replace the RNA primers with DNA).
Why is the lagging strand replicated with stretches of Okazaki fragments and that is why its synthesis is considered to be?
discontinuous

What is A strand of replicated DNA formed during prophase called?
chromatid
What is RTase?
An enzyme called reverse transcriptase, which creates a DNA strand from an mRNA strand.

What unwinds in multipule areas as dns is replicated?
The lagging strand. It is replicated in Okazaki fragments.
What is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?
RNA Polymerase
When a strand of DNA is ATCG what would the complementary pairings be for the replicated strand of DNA?
TAGC.
What does semi conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
What elongates as DNA unwinds and is replicated continuously?
Leading strand
The enzyme amylase un zips or winds the DNA strand?
The enzyme helicase unzips the DNA strand not amylase.
What happens During replication DNA .?
During DNA replication the following occurs: 1) An enzyme called helicase separates the DNA strands (the space where they separate is called the replication fork). 2) DNA polymerase adds complementary nucleotides to the separated strand of DNA. 3) The DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules.

What enzyme is responsible for decodingthe DNA strand into an mRNA?
RNA Polymerase is the enzyme responsible for creating a strand of RNA.
