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:
The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.
Explanation:
Answer:
It is dangerous if directly inhaled, it is not a very abundant energy source and it releases the most toxins when burned i think :))
Explanation:
Submarine mountain ranges(ocean spreading ridges), volcanoes, earthquakes
hope this helps
Answer:
The correct answer is :
A. we know there are four nucleotides and three sequence makes a triplet code then total possible ways are:
4^3 = 4×4×4= 64 ways.
B. The stop codons by 64 amino acid or triplet codes: TAA, TAG, and TGA then the probability would be = 3/64 = 0.0469
C. the probability that a sequence that is not a stop sequence is formed = total minus probability of stop codons:
64-3 = 61
61/64 = 0.953
D. G at end place and c should not be in the middle then:
the codes will be =
ATG
AGG
AAG
TTG
TGG
TAG
CTG
CGG
CAG
GTG
GGG
GAG
Total 12 triplet code sequences.
E. Among all these 12 codons there is only one stop codon that is TAG so the probability of this stop codon is :
1/12 = 0.083
