Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100 the same due to I. DNA Replication A. Nucleotides added to each original template strand 1. added in 5 to 3 direction 2. The two strands of DNA are antiparallel a.
run in opposite directions 3. DNA polymerase The main differentce between transcription and DNA replication is that transcription results in the formation of one singlestranded RNA molecule rather than a doublestranded DNA molecule. What are the steps in the process of transcription?
Transcript: During DNA replication, both strands of the double helix act as templates for the formation of new DNA molecules. Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesised by a multienzyme complex. DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

These chemicals can come from other parts of the body (hormones) or from the environment.
Eukaryotes initiate DNA replication at multiple points in the chromosome, so replication forks meet and terminate at many points in the chromosome. Because eukaryotes have linear chromosomes, DNA replication is unable to reach the very end of the chromosomes.
Due to this problem, DNA is lost each replication cycle from the end of the chromosome. Jun 11, 2013 Manual do Mundo Comunicao LTDA Caixa Postal CEP SP SP. Category Como ver o DNA da cebola (experincia) Duration: 6: 05. Manual do Mundo
