Answer:
The organisms that fit in boxes 2 and 7 only
Answer: mucilaginous sheath
Explanation:
These algae are known as "blue algae" because of their pigmentation or "cyanobacteria" because they are prokaryotes. Microbiologists classify cyanobacteria in the realm of Eubacteria. They are the only prokaryote algae. The cellular organization is prokaryotic, without nuclei or organelles. Respiration takes place at the level of plasmalemma and thylakoids. In the center (nucleoplasm), cells contain their genome and circular plasmids. Cyanobacteria often also have a mucilaginous sheath common to many trichomes.
These organisms contain several carotenoid pigments, particularly myxoxanthophyll, which does not occur in any other algae group. Some cyanobacteria are strictly phototrophic, others are optional: they are phototrophic when in the presence of light, but may grow in obscurity using an organic carbon source. Others can use a source of organic carbon as well as inorganic carbon, but only in the presence of light.
Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in 5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in 5' to 3' direction.
