ACIDS
: DNA AND RNA
NUCLEIC ACIDS:
• Nucleic acids are biopolymers,
macromolecules, essential to all
known forms of life.
• Are the largerst and the most complex organic
molecules. Discovered by Friedric Miescher in
1897.
•• There
NUCLEIC ACIDS:
are two types of-
• The RIBONUCLEIC ACID (RNA) and The
DEOXYRIBONUCLEIC ACID (DNA)
NUCLEIC ACIDS
CHARACTERISTICS AND FUNCTIONS
Characteristics and Functions of nucleic acids:
• diff types:
- ribosomal rna (Rrna). - messenger rna (Mrna)
.- transfer rna (Trna).
NUCLEIC ACIDS
COMPOSITION
COMPOSED OF :
01 02 03
•Polypeptides (are the building • Nucleic acids are substances with • ( DNA AND RNA are both
blocks of nucleic acids) high molecular weight ranging polymers )- a long molecule
from 1,286 to 3,000,000. made up of tiny units called
- Peptides are short chains of monomers.
amino acids linked by peptide Made up of CARBON, • The monomers that make up
bonds. HYDROGEN, OXYGEN, dna and rna are:
NITROGEN, AND
NUCLEOTIDES
PHOSPHORUS.
• Nitrogen - 15-16%
NUCLEIC ACIDS
: NUCLEOTIDES
NUCLEOTIDES
NUCLEOTIDES -linked together by
dehydration synthesis or polymerization
reactions, between the sugar of one
nucleotide and the phosphate group of
another.
• NUCLEOTIDES has its basic parts, these are:
Process: DNA
REPLICATION:
Step 1: Replication Fork Formation. Before DNA can be
replicated, the double stranded molecule must be “unzipped”
into two single strands. ...
Step 2: Primer Binding. The leading strand is the simplest to
replicate.
