Organic Molecules
Carbon Containing
Earth life is based on which two types of large organic molecules?
Proteins and nucleic acids
Nucleic acids store…
The hereditary information required for reproduction and also for synthesizing the enormous quantity and variety of protein required by an organism during its life span.
Ribosomes
Minuscules but intricately structured molecular devices found in large numbers in the cells of all known organisms on Earth.
Ribosomes handle translating the hereditary material stored in nucleic acids into proteins for use in growth, maintenance and repair.
Proteins consist of long chains known as…
Polymers
Protein polymers are made of
Amino acids
Nucleic acids
Long molecular polymers and are synthesized from nucleotides
Nucleotides
A complex molecular unit consisting of theee subunits:
- Phosphate unit
- Sugar unit (ribose or deoxyribose)
- Base unit
Earth life employs which two nucleic acids?
DNA and RNA
DNA is the repository for…
Hereditary information
RNA supervises…
The process of translating hereditary information stored in DNA, into proteins for immediate use by the organism.
Four bases of a DNA molecule
- A- adenine
- T- thymine
- G- Guanine
- C- Cytosine
What are the two base pairings of DNA?
- C-G
- A-T
Codon
A triplet of bases that specifies a specific amino acid- the initiation or termination of of the construction of a chain of amino acids constituting a protein.
