THE STRUCTURAL GENES CONTROLLED BY THE LAC OPERON
The lac operon is a set of genes that are controlled by the Lac repressor protein in Escherichia coli (E. coli) and other bacteria. These genes are responsible for the breakdown of lactose (a sugar found in milk) and other…
THE STRUCTURE OF PROKARYOTIC GENES
Prokaryotic genes are organized in a specific structure that differs from eukaryotic genes. The key components of prokaryotic gene structure include the promoter region, the coding sequence, and the terminator region. 1) Promoter Region: The promoter region is located at…
THE MOSAIC STRUCTURE OF EUKARYOTIC GENES
The mosaic structure of eukaryotic genes refers to the arrangement of introns and exons in the DNA sequence of eukaryotic genes. Eukaryotic genes are made up of sequences of DNA that code for proteins, as well as non-coding regions called…
GLOBIN GENES AND MOLECULAR BIOLOGY OF GLOBIN SYNTHESIS
Globin Gene Organization The organization of globin genes, including the beta and alpha gene families, is crucial for the synthesis of hemoglobin proteins, which are responsible for transporting oxygen in red blood cells. Here’s an overview of the organization of…
GENES AS INHERITED UNITS OF INFORMATION SPECIFYING PHENOTYPE
Genes are inherited units of information that are responsible for specifying the characteristics, or phenotype, of an organism. These characteristics can be at a gross level, such as the organism’s physical appearance, or at a molecular level, such as the…
MOLECULAR CHARACTERIZATION OF GENES AND THEIR PRODUCTS
Introduction Genes are segments of DNA that contain the genetic information necessary for the synthesis of proteins, which are the functional units of cells. The process of gene expression involves the transcription of the DNA sequence into RNA, which is…
THE SHOCKING REVELATION OF GENES STRUCTURE AND FUNCTION
Introduction Genes are the basic units of heredity in living organisms. They are segments of DNA molecules that contain the instructions for building and maintaining an organism. Genes determine the traits or characteristics of an organism, such as eye color,…
DEFINITION OF SOME GENETIC TERMS
In order to understand the Mendelian Laws and its usefulness in plant breeding, it is important to know some technical words which we shall come across in crop improvement. Genes: Genes are hereditary units or basic units of inheritance. They…
