How does mutating the DNA affect the organism?
Evgen [1.6K]
DNA mutations create genetic variation.
They could have no visible effect, no affect at all or cause something to happen, e.g cancer, or genetic mutations in the gametes lead to genetic variation in offspring. They can also lead to genetic diseases, for example cystic fibrosis or Huntingtons disease

Click and drag each label to the accurately identify the components of the visceral baroreflex
bija089 [108]

The right answers are on the attached image.


Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.

As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.

AnnyKZ [126]

Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.

Explanation:

A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins.  A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, <u>may have lost their functionality or have radically changed </u>it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:

1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.  

2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.

3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.
