The two main stages involved in protein synthesis that is in central dogma theory are transcription and translation. The process of transcription and translation occurs in the nucleus and ribosome respectively. In the translation process, DNA is used as a template and mRNA is synthesized. In translation, a protein is synthesized by translating the codon.
Further Explanation:
The double-helical structure of DNA is duplicated through a process called DNA replication. Then, the DNA undergoes a process of transcription and form RNA. After this, RNA processing starts with post-translation modification and forms three different types of RNA molecules that are rRNA, tRNA, and mRNA. Transcription mainly occurs in the nucleus of the cell. In this stage, DNA acts as a template and synthesized new mRNA. Then, the formation of protein occurs. After the process of transcription, mRNA goes into the ribosome to synthesize new protein. In TRANSLATION processes, mRNA is converted to protein. Transfer ribonucleic acid is a kind of RNA that helps in decoding a messenger RNA sequence into a specific protein.
In TRANSLATION processes, mRNA is converted to protein, but to translate mRNA, it goes under many processing before into protein mainly in eukaryotes.
- 5’Capping: In capping 7, ’methylguanosine is added to the 5’end of the transcription result by joining 5’to 5’phosphate.Capping is done only to protect the nascent mRNA from degradation and help in initiating translation.
- 3’poly A tail: Around 100-250 residue of adenine nucleotide added to the 3’end of mRNA to maintain the stability of mRNA. Firstly, the 3’end of mRNA is cleaved and makes free 3’OH. Poly-A tail help in transporting the mRNA from the nucleus to cytoplasm for the translation process.

Answer:
Rays
Explanation:
I think the answer is rays. You can see rays shooting from the sky, but it isn't matter because it doesn't have weight, only the sun does. Hope this helps!
Answer:
A forest ecosystem can support a limited number of bears because bears are the supreme predators of their ecosystem and very few animals can hunt bears so nature by supporting a limited number of bear populations supports a balanced number of population of its prey like insects, fishes, deer.
Another reason for the limited population of bear is that bear occupies the highest trophic level in the ecosystem so according to 10% law of energy transfer, it will get very less energy from its food so it needs to eat more.
Therefore the population of bears is limited because the environment can not meet the energy requirement of many bears so a forest ecosystem can support a limited number of bears.
It will be either C or D but I’m some what sure it would be letter c
<span>The biggest difference between photosynthesis and respiration is that photosynthesis only occurs in plants and some bacteria while respiration occurs in all living organisms. They do share one big similarity and that is that the process of photosynthesis is actually the same process only it is completed in reverse.</span>
