Which of the following steps happens first during transcription?
A. RNA polymerase reaches the end of the gene.
B. RNA polymerase reaches the beginning of a gene.
C. RNA polymerase pulls apart the double helix.
D. RNA polymerase produces mRNA from DNA.
Answers
The correct option for the given question about Genetic transcription is Option B) RNA polymerase reaches the beginning of a gene.
What is Genetic Transcription?It is one among the initial steps in the expression of genes. The transport of genetic information from DNA to proteins occurs sequentially through the processes of transcription and translation. During transcription, just one strand of DNA known as the template strand is replicated, and the resulting RNA is referred to as messenger mRNA.Transcription's primary goal is to create an RNA copy from a DNA sequence. The data required to encode a protein is carried by the RNA transcript.RNA polymerase is the key enzyme responsible for Genetic transcription.It creates a complementary RNA strand from single strand DNA.
Thus we conclude that during the first step of genetic transcription RNA polymerase reaches the beginning of a gene.

What's Chlorophyll ?
Answers
Answer:
Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.
Explanation:
Explanation:
Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO2 and water. Like oil spills cause damage
to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
a) How are aquatic organisms affected by oil spills in the ocean?
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
c) Name any two species of microbes which can degrade rubber from
garbage.
d) Why should there be a ban on plastic bags?
Answers
Answer: See explanation
Explanation:
a) How are aquatic organisms affected by oil spills in the ocean?
Aquatic organisms are affected by oil spilled as it is fatal and toxic to them. It can cause death, habitat degradation, vulnerability to predators and can also lead to the inability to hatch their eggs.
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
The chemical compound degraded by microbes are clearing oil spills are Pseudomonas spp and Alcanivorax borkumensis.
c) Name any two species of microbes which can degrade rubber from

The poles of the planet experience many months in a row when the Sun
never sets. Why are the North and South poles still relatively cold during
these times?
Answers
The missing options are:
A. The Sun is still low in the sky, so the solar intensity is low.
B. The Sun is low in the sky, so the solar intensity is high.
C. The poles were cooling for six months with no sunlight, and it takes a long time to warm up.
D. Both A and C are correct.
The correct answer is D. Both A and C are correct.
Even though the Sun never sets for many moths in the North and South poles, these are still cold because for them to warm up:
The Sun's rays should impact directly on the poles, as it happens with the rest of the Earth during summer.As they are large pieces of land, it takes a lot of time to warm them, and it takes more than six months to do so, even more with the Sun no impacting directly on them.In conclusion, the poles are cold because they are never positioned directly in front of the Sun since the Earth has an inclined axis. As a result, the rays directly impact the rest of Earth during its yearly journey around the Sun, resulting in high solar intensity, with high temperatures, during summer. Besides, as the Sun's rays have a very low intensity in the poles, they could never warm up these parts of Earth in six months; they need more time.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.
What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
