What does it mean when we say a gene is "turned off"? What does it mean when we say a gene is "turned off"? The gene is now acti

vated. The gene cannot be transcribed and translated into a protein. The gene has a mutation. The gene is no longer working properly.

Answer:

The gene cannot be transcribed and translated into a protein.

Explanation:

Turning off a gene means the gene cannot be transcribed and translated into a protein.

Turning off of genes is a form of gene regulation, a process that controls which genes are expressed or not expressed in a cell.

<u>The expression of genes requires that they are first transcribed from DNA to mRNA in the nucleus and then moved to cytoplasm where they are translated into proteins by the ribosome.</u>

Hence, a gene that will not be expressed has to be stopped from being transcribed amd translated by being turned off by the gene regulation process of the cell.

Answer:

A GENE IS SAID TO BE TURN UP WHEN THEY GENE CANNOT BE TRANSCRIBED AND TRANSLATED INTO A PROTEIN.

Explanation:

Genes can be turned on and off bu cells which is the process of gene regulation. Gene regulation involves the mechanisms used by cells to induce or repress the expression of a gene which is an important part of normal development. Gene regulation involves structural changes made to the gene to ensure transcription occur or prevent transcription, the genes can be bound to a specific DNA receptor and the mechanism that modifies translation of mRNA. Gene regulation helps the cell determine which gene to be transcribed and the number of protein molecules to be made at any given time. Gene regulation occurs at any point of gene expression but its most common during transcription of DNA to an mRNA molecule. Signals from the environment activates transcription factors which determines the process of transcription by binding to the regulatory regions of the genes.

(1)

Troposphere – This is the densest layer and where weather events occur

Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.

Mesosphere – Temperatures drop with altitude in this layer

Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer

Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

(2)

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.

(3)

A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

(4)

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.
