The order of nucleotides is critical in finding out the amino acid which is encoded. What do the given trinucleotides code for: AAC, ACA, CAA and CAC?
Describe why can prokaryotic cells be smaller than the eukaryotic cells and still carry on all of the functions of life?
Explain how did the theory of biogenesis lead the manner for the germ theory of disease?
Ciprofloxacin, erythromycin, and acyclovir are employed to treat microbial infections. Ciprofloxacin inhibits DNA gyrase. Erythromycin binds in front of the A site on the 50S subunit of the ribosome
Describe why gram-negative bacteria are more resistant to the biocides than gram-positive bacteria. Be specific and expressive in your response.
Clostridium and Streptococcus are both catalase-negative. Streptococcus grows through fermentation. Explain why is Clostridium killed by oxygen, while Streptococcus is not?
Restriction endonucleases are enzymes that digest the DNA. They are not similar digestive enzymes that completely digest DNA to monomers so cells can eat nucleic acids.
You add up 10 ng of pGEM to 50 ul of competent cells, and then dilute this into a total of 1 ml Luria broth after the transformation. You take 100 ul of the Luria broth and plate on and agar plate.
Explain DNA sequencing with reference to the cloning of a DNA fragment in bacteriophages M13 based cloning vector.
One of these dogs ate some of a birthday cake. Digestion and electrophoresis of DNA found at the scene of the crime with the restriction enzyme Scs1 revealed a banding pattern included of four band
Describe why a woman carrying the gene for hemophilia can generate two hemophiliac sons when she is mated to a normal male.
You failed to recover any revertants from mutants A and recovered one revertant from mutant B. This revertant was crossed with a normal wild-type strain. What proportion of the progeny from this cro
Describe the impact of chromosomal aberration during the Meiosis II, when the normal gametes produced as an end product of Meiosis II are compared with those produced from Meiosis II with the chromo
I have utilized a polyacrylamide gel in a protein analysis of fish samples. My question is why this is employed rather than an agarose gel.
Would it be possible to investigate the possible homology between the Y chromosome on an animal (example: platypus) and the Y chromosome on a human - using FISH (fluorescent in situ hybridization)?
Eukaryotic genes differ than the prokaryotic genes. Please describe, in depth, the post-transcriptional modification which a eukaryotic mRNA goes through before it leaves the nucleus and explain how
Is it possible for two people who have Down syndrome to give birth to a normal (without Down syndrome) child? If so, explain how would that be possible?
Select a chromosomal disorder from the March of Dimes Foundation Website. Recognize the disorder and describe how is it expressed in a person and inherited.
Certain trees of the similar species are known to take place with some different chromosome numbers, even although they have similar features.
What would occur if any of the gametes produced were crossed with any of the other gametes produced? (That is, crossing an abnormal gamete with the normal gamete)? Be specific.
Suppose that a single gene controls soybean seed color, and that you already know the nucleotide sequence of the wild type allele.
A primary oocyte gives mount to: four diploid egg cells, one diploid egg cell and three polar bodies, four haploid egg cells or one haploid egg cell and the three polar bodies. Explain it in detail
What event should take place during meiosis for this to happen? What syndrome is characterized by the XYY genotype? What can you learn regarding this syndrome?
Certain human chromosomal aberrations which take place during meiosis result in eggs or sperm with two copies of the X chromosome.
Explain how is sex determined in the grasshoppers? Can you find other illustrations of organisms with a similar system of sex determination?
