Bright cherry red color is produced upon the addition of methyl red indicator to a culture of a Gram negative bacilli in MR-VP broth if the organism used the mixed acid pathway of fermentation.

What is MR-VP test?

  • As part of the IMViC testing, Methyl Red (MR) and Voges-Proskauer (VP) broth is utilized as the medium in which both the Methyl Red and Voges-Prosakuer tests can be conducted.
  • It is a straightforward broth made up of dextrose or glucose, buffers, and peptone.
  • In the Methyl Red test, an infected tube of MR-VP broth is mixed with the pH indicator methyl red.
  • The acids will overwhelm the buffers in the medium and create an acidic environment if the organism employs the mixed acid fermentation pathway and creates stable acidic end products.
  • If acidic end products are present when methyl red is introduced, the methyl red will remain red.

are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location
tatyana61 [14]

Answer:

This definition suits that of "HOMOLOGOUS CHROMOSOMES"

Explanation:

Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.

Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.
