A phenotype is the physical appearance of a characteristic.
A genotype is the code for that characteristic.
Answer:
The plasmid must express a gene for ampicillin resistance (the protein product of the <em>bla</em> gene codes for beta-lactamase, the protein that breaks down ampicillin). The colonies on the ampicillin plate are antibiotic resistant. This means that they have taken up the transformed plasmids expressing both the <em>bla</em> gene and the GFP gene.
Explanation:
The transformation involved the genetic modification of a plasmid to incorporate the gene encoding the green fluorescent protein (GFP) from jelly fish. GFP makes cells glow under UV light.
In genetic engineering, scientists use antibiotic resistance as markers to indicate cells that have been transformed. By incorporating an antibiotic resistance gene such as <em>bla</em> into the vector (plasmid) and then growing the cells in antibiotic media, scientists determine which colonies have taken up the plasmid. Therefore, if the cells survive, this means that they contain the plasmid with antibiotic resistance gene as well as the GFP gene.
form cell membrane
Explanation:
It provides barriers in cellular membranes to protect the cell , and they make barriers for the organelles with in those cells. It work to provide pathways for various substance across membranes
Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
