On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells). Blue-green algae (which are prokaryotic) carry-out the photosythesis reactions in the cytoplasm.
So all of the above
Endangered Species. An animal or plant species is considered 'endangered' when it is at the risk of becoming extinct from the planet or from a particular region on the planet. Most of these species are considered to be endangered as they are at the risk of becoming extinct with only a few individuals surviving.
Answer:
The correct answer would be 2,70,000 nucleotide long gene.
The gene refers to the protein coding sequence of the (deoxyribonucleic acid) DNA.
The nucleotide sequence of a gene corresponds to the codon sequence if mRNA. The codon sequence of mRNA then codes for the amino acid sequence of the protein.
The codon refers to the set of three nucleotide which codes for a specific amino acid. For example, CAG codes for glutamine, AUG codes for methionine et cetera.
So, if the polypeptide chain consists of 90,000 amino acids then it must contain 90,000 x 3 nucleotides which are equal to 2,70,000 nucleotides.
