Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected
viktelen [127]

Answer:

the answer is A. E. coli B

Explanation:

The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect <em>E. coli</em> cells and the numbers of these <em>E. coli </em>cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that <em>E. coli </em>strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on <em>E. coli</em> K strains that carry phage λ (lysogenic for λ), but they produce plaques on <em>E. coli</em> B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.

taurus [48]

The millions of sequences were not put up together from their end and had no repeating non-coding sequences.

Explanation:

Celera Venter of Gene Myers started working in collaboration with the Human Genome project which was designed as a revolutionary concept of sequencing of human genome at a large scale. Myers break through the traditional method of sequencing and proposed of an idea of sequencing in a unique way.  

He suggested the method of breaking genome copies and then sequencing them together using LINEs. However, the declaration of this proposal by the Human project had certain failures at first as it lacked the non-coding repeating sequence.
