Modifications of Root - Tap Roots and Adventitious Roots

Modifications of Tap Roots: For Storage of Food: Tap roots of some plants become fleshy due to storage of reserve food. The main root stores extra food whereas secondary roots are thin and are involved in absorption of minerals from the soil. The swollen roots occur in different shapes. Based on their shapes, tap roots may be classified as:

Therefore, in this review, we focused on the roles of m6A modification in circRNAs during circRNA metabolism and discussed their biological consequences in human development and diseases based on current studies. Importantly, this review will provide a comprehensive understanding of m6A in circRNA biology.

Post translational modification in proteins

3/19/10 2 First modification - Modification of N-terminal met. ♦ AUG is the universal Starting codon. ♦ Hence, Met is the first amino acid in all proteins. ♦ But met has to be cleaved. ♦ It occurs as and when the protein is being synthesized. ♦ Eukaryotes: Removal of Met to expose new amino terminal. ♦ Prokaryotes: A) Removal of Formyl group.

16 Biosynthesis of the hydroxamic acid siderophore desferrioxamine D1 (DFOD1, 6), which is the N-acetylated analogue of desferrioxamine B (DFOB, 5), has been delineated. Enzyme-independent Ac-CoA-mediated N-acetylation of 5 produced 6, in addition to three constitutional isomers containing an N-O-acetyl group installed at either one of the three …

Cell Specialization | Mechanisms, Examples & Importance

As alluded to earlier, multi-cellular cells are composed of two or more cells that may have different forms, structure, function, and organization. Also referred to as cell differentiation, cell specialization is the process wherein "general" or "common" cells evolve to form specific cells that have specific functions.This process is very much prevalent and most …

Pseudouridine (Ψ) is an abundant mRNA modification in mammalian transcriptome, but its functions have remained elusive due to the difficulty of transcriptome-wide mapping. We develop a nanopore native RNA sequencing method for quantitative Ψ prediction (NanoPsu) that utilizes native content training, machine learning modeling, and single-read …

Genetically Modified Organisms | National Geographic Society

Genetically Modified Organisms. A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques. For thousands of years, humans have used breeding methods to modify organisms. Corn, cattle, and even dogs have been selectively bred over generations to have certain desired traits.

Definition of Descent With Modification - ThoughtCo

Descent with modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of heredity is the gene.Genes are the blueprints for making an organism, and, as such, hold information about its every conceivable aspect: its growth, development, behavior, …
