emmainna [20.7K]

The feature that you need to use in examining and make a determination whether the skeletal remains in the pelvis is either male or female is by analyzing its size and construction. It is because males have larger pelvis bone and are robust elements compared to females who have smaller and are light in terms of construction.

What is the effect on transcription of the structural and regulatory genes of the lac operon when lactose is present in the envi
vova2212 [387]

In the lac operon, glucose also plays an important role along with lactose. When Lactose is present in the environment along with glucose then it cannot deactivate the regulator gene [repressor], as a result, the repressor will bind to the operator and the transcription will be blocked.

When Lactose is present in the environment without glucose then the Catabolite repressor protein will bind to the CAP Site, and lactose will bind to the repressor [regulatory gene product], as a result, the repressor gets deactivated and the transcription takes place.

Lac operon: It is a set of three structural genes z, y, and a which are all transcribed and regulated under one single promoter. The three genes code for β-galactosidase, lactose permease, and transacetylase respectively.

β-galactosidase is responsible for breaking the lactose into glucose and galactose, lactose permease is responsible for transporting lactose across the cell membrane and transacetylase attaches a particular chemical group to target molecules.

fredd [130]
The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.

<span>A) Nnew = 2·Nold
B) Nnew = Nold 2
C) Nnew = Nold + 2
D) Nnew = Nold × 2</span>
