Plasmids: Plasmids are circular pieces of DNA which are capable of replicating independently of the chromosome. Plasmids are often used by scientists for the purposes of expressing foreign proteins in bacterial cells. Answer and Explanation:
For a plasmid to be useful as a recombinant DNA vector, it must have some essential features. What features are important for a plasmid that is used in recombinant DNA procedures? After transforming E.coli with the plasmids, how can we identify the cells that contain a chimeric plasmid (cont...
Eventually, the culture will become dominated by existing plasmid-free cells, leading to low plasmid yield. Plasmid Copy Number Summarized Plasmid copy number can influence experiments, and while it is appealing to have high-copy numbers for your plasmids, there are some applications where low plasm...
All living things can be divided into two types of cells: prokaryotes and eukaryotes. Eukaryotic cells have a nucleus and other cell structures that are bound by a distinct membrane. Bacteria, as prokaryotic cells, lack these internal membrane-bound structures. This distinction is considered to be...
Transformation is the uptake of foreign DNA from the environment, such as plasmid DNA, typically by bacterial cells. Plasmid transformation is the transfer of plasmid DNA between organisms. Naturally occurring plasmids often confer benefits to the bacterial host, such as antibiotic-resistance or virulen...
To achieve this higher-than-predicted stability, CPs have evolved multiple mechanisms that promote their persistence at the population level. Among these mechanisms, partitioning systems and toxin-antitoxin systems are best characterized examples, which promote segregation of plasmids into daughter cells ...
Step-by-Step Solution:Step 1: Define Recombination Recombination is the biological process that results in the exchange of genetic material between different DNA molecules, leading to the formation of new combi
The main difference between the two types of cell is thatprokaryotic cells have no (membrane-bound) organelles. This means that the processes that usually happen in organelles take place in the cytoplasm. The DNA in prokaryotes is circular, whereas DNA in eukaryotes is linear and arranged in ch...
Step-by-Step Text Solution:1. Definition of Plasmodesmata: Plasmodesmata are specialized structures that act as cytoplasmic bridges between adjacent plant cells. They facilitate communication and transport betw
1. What is the complementary strand for: 5'-ATGCATGCATGCCC-3'? How many turn(s) will this strand have? 2. Are eukaryotic cells always diploid during S phase whereas bacteria are only haploid at the end of DNA replication? Which of the following is characteristic of genes and gene regul...
