What are the 4 major types of cells? What are the main structures within the cell nucleus? What are the main structures within the nucleus of a cell? What different types of cells have an abundance of ribosomes? What cellular structure is found in prokaryotic cells, plant...
In eukaryotic cells, DNA has the appearance of a How are chromatin, chromosomes, and DNA related? Is B-DNA double-stranded with antiparallel strands? Describe one similarity between DNA and RNA. Do plant cells have DNA? Is cDNA for a DNA microarray single-stranded?
Plants, however, lack specialized mobile immune cells. Instead, every plant cell is thought to be capable of launching an effective immune response. So how do plants achieve specific, self-tolerant immunity and establish immune memory? Recent developments point towards a multilayered plant innate ...
The sex (XX) chromosomes form a sex body on the periphery of the nucleus. The chromatin of the sex body undergoes reorganization. MSCI markers have different distributions: SUMO-1 (yellow), ATR (black dots), ubiH2A (blue), H2AFX (violet). SUMO-1 marks a small nucleolus-like body of ...
In contrast, the potential roles of this posttranslational modification in mammalian cells have remained largely understudied due to a lack of suitable experimental tools and methods [131,132]. The recent generation of pHis-specific antibodies and the development of appropriate proteomic approaches to ...
Abstract Recurrent spells of droughts are more common than a single drought, with intermittent moist recovery intervals. While the detrimental effects of the first drought on plant structure and physiology are unavoidable, if survived, plants can memorize the first drought to present a more robust re...
A comparative cytogenetic analysis of Iranian Pamphagidae provides new information about the karyotype evolution in this group of grasshoppers. Two species from the Eremopeza Saussure, 1888 genus (Thrinchinae) have the fundamental chromosome number of the Pamphagidae karyotype (2n=19♂). However, ...
Over the past two to three decades, molecular and genetic studies have helped to decipher the cellular events responsible for GA activities in some model plants such as A. thaliana and rice, and this has opened the door to GA research in other plant species. In A. thaliana, DELLA regulates...
How do plant cells elongate? At the end of meiosis, are all daughter cells genetically different from parent cell? Where is DNA housed in the prokaryote cell? Which offspring of a single-celled eukaryote would inherit a mutation acquired by the parent cell?
Which structures of the cytoskeleton are found in animal cells but not in plant cells? A) Name the two organelles (one in animal cells and one in plant cells) that have their own DNA that are not located in the nucleus. B) What are the functions of each of these organelles? C) ...
