Note
diff genes have diff. nucleotide sequence
Definition
Genes are the basic units of inheritance in a living organism A Gene is a sequence of nucleotides in a DNA molecule that controls the formation of a single polypeptide.
→ a polypeptide can be used to make new proteins. Each gene → stores a message → that determines how a polypeptide should be made in cell. message stored by gene is known as genetic code
The sequence of nucleotides in a DNA molecule
- sequence is a genetic code → that determines the formation of a single polypeptide → which then all comes together to form a protein when folded together. *** check.
→ the polypeptide/protein → determines the development of characteristics in a living organism.
How Is Polypeptide or Protein Made?
Making of Polypeptide or Protein
Since there are 4 diff nucleotides, then a gene of n number of nucleotides will have different combinations
