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.

How is bacterial translation different from eukaryotic translation in terms of their processes and mechanisms?
Bacterial translation and eukaryotic translation are similar in many ways, but there are some key differences in their processes and mechanisms. One major difference is that bacterial translation occurs in the cytoplasm, while eukaryotic translation takes place in the cytoplasm and on ribosomes attached to the endoplasmic reticulum. Additionally, bacterial translation typically involves fewer initiation factors and ribosomal proteins compared to eukaryotic translation. Another difference is that bacterial mRNA often lacks introns, while eukaryotic mRNA undergoes splicing to remove introns before translation. Overall, while both processes involve the same basic steps of initiation, elongation, and termination, the specific mechanisms and factors involved can vary between bacterial and eukaryotic translation.
How are viruses different from eukaryotic cells in terms of their structure and replication mechanisms?
Viruses are different from eukaryotic cells in structure and replication. Viruses are smaller and simpler, consisting of genetic material surrounded by a protein coat. They cannot replicate on their own and rely on host cells to reproduce. Eukaryotic cells, on the other hand, are larger and more complex, with a nucleus and organelles. They can replicate independently through mitosis or meiosis.
How is bacterial translation different from eukaryotic translation?
Bacterial translation occurs in the cytoplasm and has fewer post-translational modifications. Eukaryotic translation occurs in the cytoplasm and on the endoplasmic reticulum, and involves more complex regulatory mechanisms and additional processing steps.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacterial and mammalian cells have different genetic codes and regulatory mechanisms, making it difficult for the bacterial cell to properly transcribe and translate the mammalian gene. This can result in the gene not being properly expressed or expressed with errors, leading to potential harmful effects or lack of desired function. Additionally, the post-translational modifications required for mammalian proteins may not occur in bacterial cells.
How does DNA replication differ in prokaryotes and eukaryotes?
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.

How is bacterial cell different from onion cell?
Bacterial cells are prokaryotic and the cells of an onion are eukaryotic.
Why antibiotics don't damage eukaryotic cell or viruses?
Antibiotics primarily target specific bacterial structures or functions, such as cell wall synthesis, protein synthesis, or DNA replication, which are absent in eukaryotic cells. Eukaryotic cells have different ribosomal structures and metabolic pathways that are not affected by the mechanisms of action of antibiotics. Additionally, viruses lack cellular structures and metabolic processes altogether, making them immune to antibiotics, which are designed to target living cells. Thus, antibiotics are effective against bacteria but do not harm eukaryotic cells or viruses.
Are clarithromycin ciprofloxacin the same?
No, clarithromycin and ciprofloxacin are not the same; they are different antibiotics used to treat bacterial infections. Clarithromycin is a macrolide antibiotic that works by inhibiting bacterial protein synthesis, while ciprofloxacin is a fluoroquinolone antibiotic that interferes with bacterial DNA replication. They have different mechanisms of action, spectrums of activity, and are used to treat different types of infections. Always consult a healthcare professional for appropriate antibiotic selection.

Is human DNA built the same as a plant?
The structure & replication process of eukaryotic cells DNA ie in eukaryotic plant and animal cells are same.Human cell is an eukaryotic animal cell, so its structure is similar to the plant cells but the arrangement of base sequence are different.
How are bacterial cells different from the cell of eukaryotes?
this is a very broad question. bacteria are prokaryotic and eukraryotes aren't. if you need more than this refer to a teacher or text book.
Why doesn't Tamiflu work against bacteria?
Tamiflu, or oseltamivir, is an antiviral medication specifically designed to inhibit the neuraminidase enzyme found in the influenza virus, preventing its replication and spread. Bacteria do not possess neuraminidase; instead, they have different structures and mechanisms of action. Consequently, Tamiflu is ineffective against bacterial infections, which require antibiotics for treatment.
Why Erythromycins does not destroy the 70s ribosomes in mitochondria which is inside eukaryotic cells while it destroys 70s ribosomes in bacteria?
ribosomes are created from the nucleus (protein synthesis) so ribosomes of bacterica will have different genetic information....and remember the cells can communicate with each other .e.g hormones
