What is meant by aseptate coenocytes​
spayn [35]

Answer:Filamentous fungi may contain multiple nuclei in a coenocytic mycelium. A coenocyte functions as a single coordinated unit composed of multiple cells linked structurally and functionally, i.e. through gap junctions. Fungal mycelia in which hyphae lack septa are known as "aseptate" or "coenocytic".

Coenocytic cells are present in diverse and unrelated groups of algae, including Xanthophyceae, red algae and green algae.

In the siphonous green algae Bryopsidales and some Dasycladales the entire thallus is a single multinucleate cell, which can be many meters across. However, in some cases, crosswalls may occur during reproduction.

Explanation:The green algal order Cladophorales is characterized by siphonocladous organization, i.e., the thalli are composed of many coenocytic cells.

In contrast to the Cladophorales where nuclei are organized in regularly spaced cytoplasmic domains, the cytoplasm of Bryopsidales exhibits streaming, enabling transportation of organelles, transcripts and nutrients across the plant.

a reaction that hydrolyzes a phosphodiester bond would cleave a dna molecule between a phosphate group and:
Gnoma [55]

Reactions that hydrolyze the phosphodiester bonds split the DNA molecule between the phosphate groups and the hydroxyl groups of the two sugar groups.

In DNA there is a covalent bond through a phosphate group that connects the hydroxyl group (OH) at the 5' position of the pentose sugar and the hydroxyl group at the 3' position of the pentose sugar of the next nucleotide. This covalent bond is called a phosphodiester bond because chemically the phosphate group is in the diester form.

In other words, the phosphodiester bond connects the sugar in one nucleotide to the sugar in the next nucleotide, so this bond simultaneously connects the two consecutive nucleotides to form a polynucleotide chain. If there is an enzyme that catalyzes the hydrolysis of covalent bonds that combine nucleotides, what happens is that the phosphodiester link between deoxyribose sugars will break.
