<span>Occult blood in urine is often said as the occult blood +, which means there are 10 red blood cells which is observed under the high-power microscope. And 20 red blood cells in urine means occult blood ++. If a kidney disease patient finds their urine test has +, it means their kidney inherent cells have been damaged, and the filtration function of kidneys has been damaged by the immune medium complexes.</span>

type ii restriction enzymes, such as ecori, that make staggered cuts within its recognition sequence, are considered more effect
postnew [5]

Type II restriction enzymes, such as Ecor I, that make staggered cuts within its recognition sequence, are considered more effective in biotechnology because they result in cohesive or sticky ends.

<h3>What is Ecor I and why are sticky ends important?</h3>

Ecor I is a kind of restriction enzyme which is obtained from Escherichia coli. The palindromic sequence recognized by this enzyme is 5' - GAATTC - 3'. It makes the following cuts between G and A on both the strands of the DNA to form sticky ends:

5' - G↓AATTC - 3'

3' - CTTAA↑G - 5'

Sticky ends are a fragment of DNA which is produced through a staggered cut, by the use of restriction enzyme. In this the terminal portion stretches with unpaired nucleotides. These kind of ends are easy to ligate when rDNA needs to be formed.

List the various reagents in Gram staining in correct order.
dedylja [7]

Answer:

Gram staining procedure is used to differentiate between the gram-positive and gram-negative bacteria. various reagents used in the gram staining are crystal-violet, iodine, ethanol, and safranin.

1. First, the primary strain that is crystal violet is used to stain the bacterial cells present present on the slide.

2. Then the iodine solution is added over the bacterial culture and held for 1 minute. Iodine makes a complex with the crystal violet in the cell wall of bacteria.

3. Then acetone is used as a decolorizer that decolorizes the gram-negative bacteria by dissolving its lipopolysaccharide cell wall but do not decolorize gram-positive bacteria because its cell wall is made up of peptidoglycan layer.

4. The last reagent is safranin which is used to stain decolorized gram-negative cells pink. Therefore the correct order of staining is:

         Crystal violet→Iodine→acetone→sefranine

Compared with the traditional passive drug delivery, what are the advantages of the active drug delivery method of liposomes? Ho
Dima020 [189]

Answer:

The invention of active drug loading method improves the encapsulation efficiency of some ionizable hydrophilic drugs (weak acid or weak base). The specific method is to construct pH gradient inside and outside the liposome, and then use the solubility difference of ionizable drugs under different pH conditions to realize the drug loading. With this method, the drug encapsulation rate can reach more than 95% and the drug loading can reach about 10%.
