The right option is; Hooke
Robert Hooke was an English scientist that first recognized the cell as the universal unit of life. In 1665, Robert Hooke observed honeycomb-like structure when he viewed very tiny slices of cork using a coarse compound microscope. He called the structures cells but he did not know their actual structure and function.
Answer:
To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating. ... DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.
Explanation:
Transcription is the answer you are looking for
Answer:
nucleic acids
Explanation:
Nucleic acids are the polymers of nucleotides. There are two types of nucleic acid: DNA and RNA. DNA is a polymer of deoxyribonucleotide while RNA is a polymer of ribonucleotides. The nucleotides are added together with the help of phosphodiester bonds.
Each nucleotide has a nitrogenous base, a pentose sugar and a phosphate molecule.
Answer:
Adenosine triphosphate or ATP is the energy-providing molecule of the organisms which produce energy during the metabolic process. Therefore this is also considered as the energy currency of the cell.
As a biomolecule, it is made up of three components: a ribose sugar, adenine nitrogenous base and three phosphate groups. Its adenine base is attached to the 9th nitrogen atom of the 1′ carbon of the sugar. and three phosphate group are attached to the 5' carbon atom of the sugar.
High energy is stored in the three phosphate bonds which when broken down to adenosine diphosphate and monophosphate releases energy. New ATP is generated through the process of phosphorylation in mitochondria and chloroplasts in plants. The ATP production reaction is catalyzed by ATP synthase
