STRUCTURE OF THE EUKARYOTIC mRNA GENE
Eukaryotic mRNA genes have a complex structure that includes several key components. The typical structure of a eukaryotic mRNA gene consists of the following main sections: Promoter Region: This is the region at the beginning of the gene where RNA…
DIFFERENTIATING PROKARYOTIC AND EUKARYOTIC RIBOSOMES
Ribosomes are essential cellular organelles responsible for protein synthesis in all living organisms. They are composed of ribosomal RNA (rRNA) and proteins, and they can be found in the cytoplasm or attached to the endoplasmic reticulum. Prokaryotic and eukaryotic cells…
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…
THE PRINCIPLES OF DNA PACKAGING IN EUKARYOTIC AND PROKARYOTIC CELLS
DNA packaging is a crucial process in both eukaryotic and prokaryotic cells, as it allows the long DNA molecules to be compacted into smaller volumes, enabling efficient storage and regulation of genetic material. The principles of DNA packaging differ between…
EUKARYOTIC TRANSCRIPTION INITIATION FACTORS AND THEIR FUNCTIONS
In eukaryotic cells, transcription initiation is a complex process that involves the coordinated action of multiple transcription factors. These factors play crucial roles in regulating gene expression by facilitating the binding of RNA polymerase to the promoter region of genes.…
PROKARYOTIC AND EUKARYOTIC DNA DAMAGE DETECTION AND REPAIR MECHANISMS
DNA damage can occur due to various factors such as UV radiation, chemical agents, and errors during DNA replication. Both prokaryotic and eukaryotic cells have evolved intricate mechanisms to detect and repair DNA damage to maintain genomic integrity. Prokaryotic DNA…
TRANSLATION IN EUKARYOTIC AND PROKARYOTIC CELLS
Introduction to Translation in Cells Translation is the process by which the genetic information encoded in messenger RNA (mRNA) is used to synthesize proteins. This essential cellular process occurs in all living organisms and is crucial for the expression of…
