Which bacteria is described as producing a citron pigment?
Homework Answers
ANSWER:
CITROMICROBIUM BATHYOMARINUM
It is aerobic bacterium which contains photosynthetic pigments.Strain JF- 1 is the first strain containing photosynthetic pigments.This bacteria producing citron pigment (yellow color) indicates the presence of carotenoids,this will helps in the variation of other bacteria and microorganisms.It is isolated from the deep sea plants.

(c) Individual 14 carries a recessive allele for albinism (lack of normal body pigment) which is not sex-linked. She marries a man who is also a carrier for albinism but who does not carry the hemophilia allele. The genes exhibit independent inheritance. Using the symbol a for albinism and A for normal pigmentation, show by means of a suitable genetic diagram, the probability of this couple producing a male child who has both hemophilia and albinism.

If a bacteria is positive for mannitol fermentation, when it is incubated in CTA mannitol, the media turns yellow. This is because: When the bacteria comes into contact with mannitol, it produces a yellow-colored pigment. Fermentation of mannitol produces yellow metabolites. Fermentation of mannitol produces acids, which lower the pH of media. Therefore, the pH indicator turns yellow. Mannitol turns the media yellow.
Albino rabbits lack pigment and are homozygous for the recessive allele c (C allows pigment formation)....
Albino rabbits lack pigment and are homozygous for the recessive allele c (C allows pigment formation). Rabbits homozygous for the recessive allele b make brown pigment, while those with at least one copy of B make black pigment. True-breeding brown rabbits were crossed to albino rabbits (that also had the genotype BB). The F1 rabbits, which were all black, were crossed to rabbits with a double recessive genotype (bb cc). The progeny obtained were 34 black, 66 brown, and 100...

Albino rabbits (lacking pigment) are homozygous for the recessive c allele (C allows pigment formation). Rabbits homozygous for the recessive b allele make brown pigment, while those with at least one copy of B make black pigment. True-breeding black rabbits were crossed to albinos. F1 rabbits, which were all black, were crossed to the double recessive (bb cc). The progeny obtained were 40 black, 60 brown, and 100 albino. What phenotypic proportions would have been expected if the b and...

In Grove snails, gene A codes for the production of black pigment. The dominant allele A blocks the production of black pigment, leaving the shell yellow. Pigment is only produced in homozygote recessive aa. A second gene, D, controls where pigment is deposited, with the dominant allele D restricting pigment deposition to a narrow striped area (see Fig. at right). Genotype dd leads to uniform pigment deposition across the shell. Following several dihybrid crosses (AaDd × AaDd), the ratio of...

To make bacteria produce certain aminoacid in industrial quantities, the most commonly used approach is: A. Find the gene which encodes this aminoacid in human genome, and introduce this gene into bacteria B. Find wild bacteria producing this aminoacid in large amounts and engineer the genome of this bacterium to make it overproduce it in even larger quantities C. Mutate the bacterium in order to make sure it will acquire the gene for this aminoacid D. Cross the bacterium which...
