Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?

Answers

Answer:

The rapid decolorization with ethanol or acetone

and counterstaining with safranin

When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?

Answers

Answer:

No that is not the father

Explanation:

The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.

Can someone help me with this bio question plss!!!!!!!!

Answers

Answer:

it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef

Answer:

Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.

Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

Place the steps of constructing a genomic library in order. I. Digest phage with restriction enzyme. II. Lyse cells of interest and precipitate DNA. III. Introduce constructs via transformation into competent E. coli cells. IV. Perform ligation reaction with genome fragments and phage. V. Digest genomic DNA with restriction enzyme.g

Answers

Answer:

The correct answer is -

II: lyse cells of interest, precipitate DNA

V. Digest (cut) genomic DNA with restriction enzyme

I. Digest (cut) phage (chromosome) with restriction enzyme so can ligate in the gene in next step!!

IV. Perform ligation (glue plasmid in!) reaction with genome fragments and phage.

III Introduce constructs via transformation into competent E. coli cells.

Explanation:

The total collection of the genomic DNA of an organism is known as the genomic library of the particular organism. In this library, the genomic DNA is inserted and stored in identical vectors.

The genomic library construction involved some major steps that are:

- Extract and purify DNA - lysing and separating the desired DNA of interest.

- Digest the DNA with a restriction enzyme - breaking or digesting DNA into fragments with restriction enzymes

- cut phage (chromosome) with restriction enzyme

- Insert the fragments of DNA into vectors

- introduce these recombinant a host bacterium by transformation, creating a DNA library.

Comparative features of amino and fatty acids

Answers

Hopes this helps:

Answer:

The main difference between amino acids and fatty acids is that amino acids are the building blocks of proteins whereas the three fatty acids bound to a glycerol and form a triglyceride, which is the main constituent of fat. Amino acids and fatty acids are two types of building blocks of macromolecules of the body.

Like replication and transcription, translation is a process in which the information present within a nucleic acid template is used to guide the synthesis of a new polymer. But the translation machinery is much more complex than the machinery involved in replication or transcription. Discuss the aspects of translation that make it so challenging for the cell.

Answers

Answer:

The aspect of translation that makes it so challenging for the cell is that it involves too many steps and too many molecules and organelles. mRNA associated with rRNA and tRNA. rRNA reading mRNA in a specific direction. Codon sequences indicating where to start and where to finish the synthesis. Different codons codifying for different aminoacids and tRNA recognizing those codons to add the correct amino acid to the chain. If the protein is destined to exportation, RER and Golgi complex are also involved in the process.  

Explanation:

In protein synthesis, the first step is to synthesize messenger RNA, mRNA. The transcription is the coping process of the DNA section, and it happens in the nucleus. After that, the translation occurs when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.

Once in the cytoplasm, it begins the translation process. mRNA meets a free ribosome, which is the primary structure for protein synthesis. Ribosomes are composed of two subunits, a big one and a small one. They also associate with different tRNA that carrying amino acids. Ribosomes might be floating freely in the cytoplasm or can be attached to the rough endoplasmic reticulum.

The ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.  tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.  

Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.  

The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.

And if the protein is destined for exportation or cell membrane, its synthesis also involved organelles like the Rough endoplasmic reticulum and the Golgi complex.

Mendel determined that for a given character(i.e. pea seed shape) an individual has two factors that these can exist in two forms (R or r). Today we would describe R and r as being:______.
a. different alleles of the seed shape gene.
b. different genes of the seed shape locus.
c. different genotypes of the seed shape character.
d. different loci of the seed shape gene.

Answers

Answer:

a. different alleles of the seed shape gene.

Explanation:

Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene locus. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
