In a human cell, what would happen to DNA replication during interphase of the cell cycle if there were a single origin of repli
Dominik [7]

The question is incomplete as it does not have the option which are:

  • No DNA replication would occur because DNA isn’t replicated during interphase.
  • All chromosomes would be replicated, but more slowly than usual.
  • A single chromosome would be replicated.
  • No DNA replication would occur because multiple origins of replication must interact to replicate DNA.

Answer:

All chromosomes would be replicated, but more slowly than usual.

Explanation:

Origin of replication refers to the sequence of the DNA in the genome of the organism where the process of replication begins.

The opening of the origin of replication allows the binding of the replisome complex at the terminals which initiates the process of the replication.

The number of origin of replication varies in the prokaryotes and the eukaryotes as the prokaryotes possess only one chromosome which requires only one origin of replication but eukaryotic chromosomes are large which contains multiple of origin of replication.

In the given condition if the chromosome contains only one origin of replication then the replication process will get slower as the large size of the eukaryotes will have to be replicated by only one Ori sequence.

Thus, the selected option is the correct answer.

The largest of the brain's lobes, the _____ lobe, is where multiple cognitive functions are performed. group of answer choices
Aloiza [94]

The Frontal lobe is the largest brain lobe.

Frontal lobe is the largest lobe of the brain where most important activities of the body like the voluntary movements are controlled.

It is the region which determines the personality, thinking, reasoning, memory, speech and logical ability of the human body.

This region has the ability to manage high level functions to maintain the system of the human body.

This lobe contains the largest part of the brain i.e. Cerebrum.

Cerebrum receives sensation of the thought and activity of the body. It is divided into the right and left hemispheres joined through a network of nerve fibers i.e. corpus callosum.

It is responsible for the behavioral function and the speech.

Broca's are and Wernick's area is present in this lobe which control the speech and understanding.
