What are the basic building blocks of dna and rna? a. nucleotides b. phosphorous c. proteins d. sugar

a;nucleotide

Explanation:a nucleotide is the building block of the Nucleic Acids. It forms the component part of the nucleic acids.A nucleotide usually contains a nitogeneous base, a five carbon sugar and phosphate group.

Nucleic acids may be ribonucleic acid RNA or deoxyribonucleic acid DNA. Nucleic acids functions to carry information which directs the synthesis of proteins and transmits genetic information.

However RNA and DNA can be differentiated based on the pentose sugar they contain.RNA contains a ribose sugar and DNA contains a deoxyribose sugar, due to the removal of an oxygen atom.

Nucleotide may undergo condensation to form polynucleotide

the national environmental policy act (nepa) is a united states environmental law that promotes the enhancement of the environment and established the president's council on environmental quality (ceq). the law was enacted on january 1, 1970. to date, more than 100 nations around the world have enacted national environmental policies modeled after nepa.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
