Question

Which or the following can make competent bacterial cells? A) Exposing cells to a strong electric field B) Treating the cells chemically C) Anything that makes the cell membrane more permeable to DMA D) Allowing the culture to enter stationary phase growth E) All but D A purine is a ______ molecule, while a pyrimidine is a ______ molecule. A) one-ring, two-ring B) one-ring, one-ring C) two-ring, one-ring D) two-ring, three-ring E) two-ring, two-ring TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. In the case of genetic exchange in bacteria by transformation, there is an exchange of DNA back and forth between cells, and a complete diploid cell is formed. All the cells in a bacterial colony are genetically identical. In F+ times F- crosses, none of the bacterial chromosome is transferred only the F factor is. A ______ inversion involves the centromere. A) paracentric B) chromocentric C) concentric D) epicentric E) pericentric

Explanation / Answer

Cells can be make competent by treating cells to strong electric field, treating cells chemically, anything that uptakes DNA, Allowing the culture to enter stationary phase growth.

A purine is a 2 ring carbon nitrogen molecule and pyrimidine is 1 ring carbon nitrogen molecule.

3. True

4. True.

5. True.

A pericentric inversion involves centromere
