Nucleic Acids Flashcards
What’s the definition of a double helix ?
Shape of DNA molecule,due to coiling of the 2 sugar-phosphate backbone strands into a righthanded spiral configuration.
What’s a monomer?
Molecule that when repeated makes up a polymer.
What are amino acids monomers of?
Proteins
What are nucleotides monomers of?
Nucleic acids
What is a nucleotide?
Molecule consisting of a five-carbon sugar, a phosphate group and a nitrogenous base.
What’s a polynucleotide?
Large molecule containing many nucleotides
What are nucleotides roles in biochemical processes?
-They form the monomers of nucleic acids
-phosphorylated nucleotides like ATP and ADP are crucial for energy transfer in cells
-they help regulate many metabolic pathways
-some are components of coenzymes, like NADP used in photosynthesis
What’s a phosphorylated nucleotide?
What are some examples?
What do they do?
A nucleotide that contains more than one phosphate group.And are energy-rich molecules
Examples include ATP and ADP
-they drive energy-requiring metabolic processes
-help regulate many metabolic pathways
-some are components of coenzymes
What are some things nucleotides do?
-form the monomers of nucleic acids (DNA and RNA)
-become phosphorylated nucleotides
-to help in metabolic processes
-help regulate many metabolic pathways
-may be components of coenzymes
What are the components of a nucleotide?
5-carbon sugar (Pentose sugar), phosphate group and a nitrogenous base
What’s the role of cytoskeletons in the human skin cells?
Providing mechanical strength to the cell and the transport of organelles within the cell
