Question

nit 5.1
Which of the following characteristics is not true of a plasmid?
A. It is a circular piece of DNA
B. O It is required for normal cell function
. It is found in bacteria
. It can be transferred from cell to cell​

Answer 1

It is required for normal cell function (B) is not a true characteristicsof a plasmid

Explanation:

1.Transfer of this DNA to another cell is referred to as transduction.

2.Transferred DNA once inside the infected bacterium can either exist as transient extrachromosomal DNA, like a plasmid, or it can integrate into the host bacterium's genome through homologous or site directed recombination.

3.Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

4.Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly one thousand DNA base pairs to hundreds of thousands of base pairs.
