The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The information contained in the genes will be used to make thousands of proteins involved in the functioning of the cell. The first step in the expression of a gene is to copy its information in the form of a molecule very close to DNA, ribonucleic acid or RNA.
The main difference between DNA and RNA is the presence of an extra oxygen atom on each of the nucleotides of the RNA. This addition provides greater flexibility to the RNA, allowing it to fold on itself to form propellers. Due to its structural properties, RNA takes a wide variety of forms and ensures a variety of roles in the cell. DNA, on the other hand, is more static and stable, and its essential function is the storage of information in the form of a double-stranded helix. Another change: in RNA, thymine (T) is replaced by uracil (U).
In the transcrption of DNA, the strand of the RNA formed is complementary to that of the DNA:
* A is matched to the U
* T is matched to A
* C is paired with the G
* G is paired with C
Answer:
The correct answer is mesosphere.
Explanation:
The atmosphere exhibits five distinct layers, which are determined by the modifications in temperature that take place with the upsurging altitude. These are troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Of the mentioned layers, the mesosphere, that is, the layer present above the stratosphere is considered as the coldest layer of the atmosphere. The coldest portions of the atmosphere are situated in this layer and can reach up to -90 degree Celsius.
Answer:
(CFC) production has been linked to an increase in the occurrence of skin cancers caused by holes in the ozone layer.
B) Chlorophyll molecules are the largest of the all pigment molecules.
C) Chlorophyll reproduces faster than the other pigments.
D) Green is the color of the spectrum most easily seen by humans.
If yellow, red, and orange pigments exist in the leaves of trees. The leaves appear green except for the autumn because the chlorophyll is the most abundant of all the pigments present. Thus, the correct option is A.
Chlorophyll is a pigment which is present in all the green plants and in a few other organisms such as algae. It is required for the process of photosynthesis, by which light energy is converted into chemical energy in the plants. The chlorophyll pigment is responsible for the green coloration in plants.
However in the autumn, because of changes in the length of daylight and temperature, the leaves stop the food-making process. The chlorophyll pigment breaks down, the green color disappears from the leaf, and yellow to orange colors become visible in the leaves and give the leaves part of their fall splendor.
Therefore, the correct option is A.

Biotic components or biotic factors are any living organisms that affect another organism. These components shape an ecosystem which includes animals that consume organisms in question and its living food that the said organisms consume. Biotic components include human influence. Producers, consumers and decomposers usually comprise biotic components.
The biotic component of an environment are (a) plants and animals because only plants and animals are living
Biotic components are the living parts of an ecosystem. They include plants, animals, bacteria, and fungi. Biotic components interact with each other and with the abiotic components of the environment.
Abiotic components are the non-living parts of an ecosystem. They include air, water, soil, and sunlight. Abiotic components provide the physical environment for biotic components to live and grow.
So the answer is (a), plants and animals.

Correct answer: Isostasy
Isostasy is the state of gravitational equilibrium between the mantle and the earth's crust. It tries to explain how different topographic heights exists on the earth surface.
It tries to balance all large portions of the earth's lithosphere. It controls the regional elevations of oceans and continents according to the density of rocks.
