When does DNA needs to be replicated?
DNA has to be in a unwound (or stretched out) conformation for both replication and transcription. During replication, an identical copy of the DNA is created. During transcription, an mRNA is synthesized from the DNA template strand. WTF some of us are still in school can you help us with some simpler terms wow
Where does Dna replication and transcription take place?
Both of these 'Distinct Processes' occur within the Cell's Nucleus.
Is DNA transcription the same as DNA replication?
No - they are different processes, although both use a DNA template. DNA transcription is the copying of DNA to create mRNA, which is then translated into a polypeptide (protein). DNA replication creates a new strand of DNA.
What enzyme attaches and adds the matching nucleotides?
DNA Polymerase III adds nucleotides during DNA replication. DNA Polymerase I also adds nucleotides (to a lesser extent). DNA Pol I is responsible for replacing the primers with dNTPs, these sections are then joined to the rest by DNA Ligase.
How does topoisomerase affect the DNA strand during DNA replication?
The topoisomerase enzyme uncoils the double helical structure of DNA during its replication to form the replication fork. In eukaryotes both posive and negative supercoils get unbind by topoisomerase I & II respectively.Topoisomerase isomerase unwinds DNA to form replication fork
How are DNA replication and transcription similar?
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication. Also in DNA replication the compliment of Adenine is Thymine. In transcription the compliment of Adenine is Uracil.

What enzyme catalyzes DNA replication?
one of them is heliocase. it 'unzips' the DNA strand. You can always remember this because it's in a popular joke: Q. Why is the enzyme heliocase a lot like a teenage boy? A. They both want to unzip your jeans (genes) !!!!!

The process of transcription is similar to the process of DNA?
Replication and transcription involves a parental DNA strand that is the foundation on which the products are built on.Replication and transcription both have initiation step which involve the breakage of the parental DNA strand.Replication and transcription both have specific proteins that keep the polymerase molecule attached to the parental DNA strand. There are elongation factors for transcription and sliding clamp for replication.Both processes use DNA topoisomerases to relieve supercoiling.Both processes only proceed in the 5' to 3' direction.Replication and transcription both involve the addition of specific 3' endings. In replication, it is the addition of the GGGTTA sequence by telomerase. In transcription, it is the addition of the poly-A tail.Both processes used nucleotides as the language on which the daughter strands come from.Replication and transcription involve the hydrolysis of a phosphodiester bonds to begin their process.Both processes take place in the nucleus.

In what direction does a DNA molecule split during replication?
In both directions.

When does replication occur in cell's cycle?
Replication of DNA occurs during Interphase of both mitosis and meiosis. This means the DNA is doubled before the cell divides.
When does replication happen during mitosis or meiosis?
replications occurs in both meiosis and mitosis during the S portion of interphase.
Compare and contrast the process of DNA replication to RNA transcription?
DNA replication means that the entire strand of DNA is copied. You end up with two double stranded DNAs that are full length. The four bases that make up DNA are A,T,G & C. Transcription is the copying of just a small section of DNA. From ChaCha!
