Describe the intracellular events that occur when a population of wild type ( lac+) escherichia coliis transferred from a medium
denis23 [38]

The lac repressor protein is bound to the operator region of the lac operon when there is no lactose in the medium. When introduced in lactose, it binds to an allosteric site on the repressor causing its to change conformation and release from the operator. This allows the polymerase that is bound to the promoter region to proceed transcription of the lac operon genes (LacZ, Lac A, and Lac Y). Translation of these genes forms enzymes that enable the organism to break down lactose for energy.

If an organism has a diploid number of 6 chromosomes, how many different combinations of maternal and paternal chromosomes are p
Alexxandr [17]

The different number of maternal and paternal chromosomes possible will be 8. that is option A is correct.

Chromosomes are defined as the genetic material within the body. They are thread like structures within the DNA and are made of proteins. In general human body has 23 pairs of chromosomes out of which 22 are numbered while 1 is the sex chromosome. Gametes are genetic material that are generally haploid in nature and they carry only one chromosome along with them. According to the question, there are 6 diploid chromosomes present which means there are 3 pairs of chromosomes. So each gametes will have a total number of 3 chromosomal pairs irrespective of their type that is maternal or paternal. Therefore combination of maternal and paternal chromosomes are given by

Combination = 2ⁿ where n is pair of chromosomes and here n = 3

Combination = 2³ = 8
