DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
The answer is B) ATP + oxygen --> ADP + P
Adenosine triphosphate (ATP) is the energy currency stored in every living cell. ATP is a complex molecule which composed of the nucleoside adenosine and a tail of three phosphates. Normally energy is released from the ATP molecule by a reaction that removes one of the phosphate-oxygen groups and becomes adenosine diphosphate (ADP). Thus, ATP converts to ADP to liberate energy. ADP soon after release, it is recharged in the mitochondria and comes out again as ATP.
Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA. During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs. RNA polymerase moves from the 3 'end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA. Therefore, D. Nucleic acids attach to the bases in the DNA.
