DNA STRUCTURE 3.3.3 page 63-74. What are the monomers of the nucleic acids? What are the elements found in the nucleic acids? Where is DNA found in a prokaryotic cell? In eukaryotic cell. STRUCTURE OF NUCLEIC ACIDS. Types of nucleic acids :. Polynucleotide 3.3.3.
Where is DNA found in a prokaryotic cell? In eukaryotic cell
* This process is called semi-conservative replication. Why?
3.5 Transcription, translation
tRNA (transfer RNA):
rRNA (ribosamal RNA)
There are 64 different codons
Whatis the amino acid
sequence of a polypeptide
which is produced from this
tRNAmolecules transfer amino acidsaccordingtocodon anti-codonrecognition.
In the past it is believed that each gene codes an enzyme. This hypothesis is called one gene-one enzyme.
After further researches, one gene one enzyme hypothesis is modified as one gene one polypeptide
Each gene works by coding for the synthesis of one particular protein, such as an enzyme.
1- What will be nucleotide sequence of the complementary strand of this DNA strand?
2- What will be nucleotide sequence of the mRNA which is transcribed from this DNA strand?
3- What would happen to the DNA strand after transcription?
