How is bacterial DNA replication different from eukaryotic DNA replication in terms of process and mechanisms?
Bacterial DNA replication is simpler and faster than eukaryotic DNA replication. Bacteria have a single circular chromosome, while eukaryotes have multiple linear chromosomes. Bacterial replication occurs bidirectionally from a single origin, while eukaryotic replication starts at multiple origins. Bacteria use a DNA polymerase III enzyme for replication, while eukaryotes use multiple DNA polymerases.
Some organisms use single-stranded rather than double-stranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
DNA helicase
What are two differences between transcription and DNA replication?
# Transcription is copying a section of DNA (a gene) onto a mRNA molecule. Replication is the copying the entire DNA molecule. # Transcription does not require primer for initiation.DNA replication use primer for initiation. # RNA transcription, mRNA copy of the active stand of DNA helix is made this process is carried by different enzyme & result is a single of mRNA.DNA replication double helix of DNA is duplicated into two identical double helix which are also identical to the mother DNA, this process is carried by specific enzyme
What enzyme do scientists use to cut genes out of strands of DNA?
Scientists use an enzyme called restriction enzyme to cut genes out of strands of DNA.
Which restriction enzyme did you use to cut the DNA?
The restriction enzyme used to cut the DNA was EcoRI.
How are copies of DNA made?
DNA is copied by breaking the hydrogen bonds keeping it together, separating itself into two complimentary strands. Lone base pairs in the nucleus attach to the now single stranded DNA, creating two identical strands of DNA.nnnlknlk A DNA molecule is copied in a process called DNA replication. During DNA replication, the enzyme helicase separates the two strands of DNA nucleotides. The nitrogen bases of the two strands of DNA nucleotides are exposed, and the enzyme DNA polymerase causes new DNA nucleotides to pair with the original, exposed nucleotides according to the base-pairing rule. The result is two identical DNA molecules, each having a new strand of DNA nucleotides, and an original strand of DNA nucleotides. This kind of replication is called semi-conservative replication.
Some organisms use singlestranded rather than doublestranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
Some viruses have single stranded DNA molecules. These viruses do not have the machinery to synthesise the DNA on their own. They insert their DNA in a living cell where the DNA synthesis takes place.
How do DNA gyrases and helicases differ in their respective functions and modes of action?
Helicases are involved in the unwinding of DNA double helix at the replication fork. When one part of the DNA is unwound the other part is overwound which exerts strain. DNA gyrases introduces negative supercoiling to reduce the strain.
What is Replication of an RNA virus?
You might be referring to the reverse-transcription that many retroviruses use (a virus with an RNA that turns into DNA). By using the enzyme reverse transcriptase, viruses like HIV can make a DNA from RNA template.
What uses bacteria to copy DNA?
They can reproduce very quickly
Is the process of polymerase chain reaction similar to the process of DNA replication which occurs in cells true or false?
True. The process of polymerase chain reaction (PCR) is similar to the process of DNA replication that occurs in cells. Both processes involve the use of DNA polymerase enzyme to synthesize new strands of DNA using a template strand. However, PCR occurs in a controlled laboratory setting and amplifies specific target DNA sequences, while DNA replication is a natural cellular process that duplicates the entire genome.
Which best describes a difference between transcription and DNA replication-?
Another answer could be that Transcription uses Uracil. This is the answer I got from Apex btw.
