learning objectives
At the end of the 60- minute lesson, the students are
expected to achieve the following objectives with at
least 85 % of level profiency;
11.
Define DNA and RNA;
2.
Describe the structure of DNA and RNA molecule
3.
Differentiate DNA from RNA in terms of their
structure, components, functions and locations
DNA

DEOXYRIBONUCLEIC
ACID
DNA is a molecule that contains the
instructions an organism needs to
develop, live, and reproduce. DNA is
found mainly in the nucleus of the cell.
DEOXYRIBONUCLEIC
ACID
DNA is a long-thin molecule made up of
nucleotides.
Each nucleotides contains;
·Phosphate Groups
·The sugar DEOXYRIBOSE and Nitrogenous bases:
Adenine (A), Thymine (T)
Cytosine (C), Guanine (G)
RIBONUCLEIC ACID
RNA, just like DNA, is made of nucleotides.
Each nucleotide is composed of
·Phosphate group
·The sugar ribose and Nitrogenous bases
Adenine (A), Uracil (U)
Guanine (G), Cytosine (C)
DEOXYRIBONUCLEIC
ACID
RNA is used to translate instructions from DNA
to make proteins. RNA in turn then contains
the codes for the primary sequence of amino
acids to make proteins.
1. Messenger RNA (mRNA) transcribes the DNA
nucleotide bases to RNA
nucleotide bases
3 types of
rna
2. Ribosomal RNA (rRNA) binds the mRNA and tRNA to
ensure that codons are
translated correctly
3. Transfer RNA (tRNA) translates the mRNA codons
into the correct amino
acids.
Any
questions?
