Answer: A. becoming transcriptionally active
Explanation:
Regions that are sensitive to the enzyme DNase I, are regions of chromatin that lost their condensed structure, thereby leaving the DNA accessible and exposed to degradation by the DNase I enzymes. These Chromatin regions become transcriptionally active
.
These regions are referred to as DNase I hypersensitive sites.
The correct answer is reuptake.
The reabsorption of a neurotransmitter by a neurotransmitter transporter situated along the plasma membrane of an axon terminal or glial cell after it has done its activity of conducting a neural impulse is called reuptake.
The process of reuptake is essential for usual synaptic physiology as it permits for the recycling of neurotransmitters and monitors the neurotransmitter level in the synapse, thus, monitoring the duration of the signal resulting due to the discharge of the neurotransmitter.
In an animal cell, the organelles that are present are:
The nucleus,
The endoplasmic reticulum,
The golgi apparatus,
The lysosomes,
The ribosomes,
The vacuoles,
The centrioles,
The mitochondria,
nucleolu, vesicle, rough endoplasmic reticulum, cytoskeleton, smooth endoplasmic reticulum, cytosol
Answer: C
Explanation:
When breeders notice a unique trait of interest and selectively breed to increase their population, there is tendency of also increasing the population of lethal genes. This happens via a situation known as inbreeding depression. There is a tendency to mate closely related individuals in a bid to increase the occurrence of a desired phenotype. However, in a situation where these animals have a recessive lethal gene, it may result in a double recessive thus becoming obvious in the population.
