what would happen if the DNA fragment taken into the cell was not homologous to anything in the bacterial genome? (transformation)
if the DNA fragment taken into the cell was not homologous to anything in the bacterial genome then bacterial defence system recognise it as Foreign material and restriction endonuclease will cut this DNA fragment and degrade it.

What is bacterial transformation? What are the differences and similarities between transforming a bacterial cell with a plasmid and with a DNA fragment?
1. Homologous recombination can happen between non-identical DNA sequences. T/F? 2. Homologous recombination can happen in_______ a) meiosis b) mitosis c) both 3. Homologous recombination in meiosis has the main purpose of_____ a) DNA repair b) Creating new chromosomes c) Sealing double-stranded breaks 4. Strand invasion usually happens without enzymatic assistance. T/F? 5. When replication fork runs into a nick, it results in a_______ a) single-stranded break b) double-stranded break 6. The invading end is usually a _______ a) 3'...
If DNA receptors on the cell surface of a bacterial cell were mutated and nonfunctional, how would that effect the bacterial cell? -The cell would die. -The cell would be incapable of accepting naked DNA from the environment. -The cell would be incapable of integrating naked DNA from the environment into its genome. -The cell would be incapable of conjugation. -The cell would be incapable of transduction.
If 100% of the DNA contents of a transducing bacteriophage were DNA from the host chromosome, what would happen when the bacteriophage infected a new bacterial cell? Group of answer choices The bacteriophage would be converted from a lysogenic phage to a lytic bacteriophage. The new bacterial cell would die. No more bacteriophage would be synthesized, as there is no bacteriophage genome available to direct synthesis. More bacteriophage would be synthesized, resulting in death of the new bacterial cell. The...
Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...
A T4 bacteriophage transfers a random fragment of DNA from one E. coli cell to another E. coli cell. This phenomenon is an example of a. conjugation b. transformation c. transduction d. none of the above
Question 6 1 pts What would happen at the end of meiosis lif the homologous chromosomes did not separate during anaphase? One daughter cell would be 4n; the other would have no chromosomes. Both daughter cells would be 4n. Both daughter cells would be 2n. One daughter cell would be 2n; the other would have no chromosomes, Facebook Facebook Eme Facebook KON < Previous
DNA taken in via conjugation must be integrated into the host cell genome to be used. True or false? Explain your reasoning.
In order for cell division to occur, what has to happen to DNA? (there are two major things)Why? How do both processes work?
If the size of your gene (DNA fragment) was 1815 bp, what would be the likely molecular weight of the protein encoded by this gene?
