Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.
The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.
<span>Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.</span>
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:hey I’m actually early this time ayyyy wazup
Explanation:
Answer:
It is possible since a receptor can activate different signaling pathways in different cell types
Explanation:
In a cell, a receptor bind to a specific ligand to activate a signaling pathway, while the same receptor may bind either with the same or another ligand in another cell type and thus activate another signaling pathway
Answer:
That would be true!! Hope this helps.
