The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.

Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.

Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

Answer:

There are a number of lipids that are found in foods and contribute to various functions in the body. Triglycerides are the most common lipid found in food and in the body; they consist of a Glycerol backbone attached to three fatty acids.

Fatty acids are classified based on the degree to which the carbon chain is saturated with Hydrogen

A fatty acid is saturated if it contains no carbon-carbon double bonds, polyunsaturated if it contains two or more carbon-carbon double bonds, and monounsaturated if it has only one carbon-carbon double bond.

The unsaturated fatty acids can exist in one of two structural forms: the trans form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of that bond.

When hydrogens on an unsaturated fatty acid lie on the same side of the carbon-carbon double bond, a cis formation exists.

7. Why do the Amoeba Sisters consider the mitochondrion a big deal?

IceJOKER [234]

Answer:

Mitochondria are famed as the energy factories of eukaryotic cells, the seat of an array of membrane-bound molecular machines synthesizing the ATP that powers many cellular processes.

Sphinxa [80]

IV only

Plate IV will only have the trangenic E Coli hence will have the highest percentage of bacteria that are expected to produce insulin.

Explanation:

The transgenic E. coli will have taken up the plasmid with the insulin and amp genes hence they will be able to survive and grow in amplicilin antibiotic.

In plate IV, the wild type E. coli will be eliminated by the antibiotic (because they do not have the gene for resistance) hence providing no competition for resources, in the agar, with the transgenic E coli. This will ensure optimal growth for the transgenic E coli even, than in plate III, producing highest percentage of insulin.

Which statement describes a common measurement error?

Kitty [74]

Answer – C (Using instruments that have not been calibrated).

When the integrity of an instrument’s calibration has been compromised (usually due to exposure to a shock, vibration, or physical damage), it needs to be calibrated; failure to do this inevitably leads to inaccurate measurement; this is a very common measurement error.
