EXTRA CHROMOSOMAL INHERITANCE & GENOME IMPRINTINGBiswarup Nandi
Cytoplasmic Inheritance:
Imagine genetic information passing from a mother to her child. It happens through tiny structures called organelles in the cell.
These organelles have their own set of instructions, separate from the cell’s nucleus.
Why is this important? Because it affects how traits are inherited!
Genomic Imprinting:
Think of it like a “parental tag” on genes. Some genes behave differently depending on whether they come from the mother or the father.
Epigenetics plays a role here—it’s like a switch that can turn genes on or off.
This process affects development and can lead to certain diseases.
Remember, these concepts help scientists understand how our genes work and why we’re unique! 🧬
Introduction
Maternal Inheritance
Organellar inheritance
Mitochondrial inheritance
Chloroplast inheritance
Inheritance involving kappa particle
INTRODUCTION
DNA or RNA is the Genetic materials carrying information from
one generation to another.
Besides these two nucleic acids the cytoplasm also
contributes to the inheritance of some characters in some
organisms.
Extra chromosomal inheritance is also defined as nonmendelian inheritance
Inheritance due to genes located in cytoplasm plasmagenes.
The genes are located in DNA present in mitochondria and in chloroplasts these
are called organellar genes. This type of inheritance is also called as
cytoplasmic inheritance.
The evidence of cytoplasmic inheritance was first presented by Carl Correns in
mirabilis jalapa.
In 1943, Sonnenborn discovered Kappa Particles in Paramecium and they are
inherited through cytoplasm.
In cytoplasmic inheritance the character of female parent is only transmitted to
the progeny
MATERNAL INHERITANCE
The character of only one of the two parents (usually female parent) is
transmitted to their progeny.
It is usually referred to as extra-chromosomal or maternal or uniparental
inheritance.
The transmission of cytoplasm differs between sex cells:
Sperm or pollen transfer little or no cytoplasm to the zygote, but Egg
Contributes almost all of the cytoplasm to the zygote
This pattern of mtDNA inheritance is well known as "maternal
inheritance.
ORGANELLAR INHERITANCE
The cytoplasmic organelles like plastids (chloroplast) and
mitochondria are involved.
The cytoplasmic inheritance is governed by the genes of
mitochondria and chloroplast.
The genes which involve in cytoplasmic inheritance are called
plasma genes or cytoplasmic genes or extra nuclear genes.

F. Questier, Computer security, workshop for Lib@web international training program 'Management of Electronic Information and Digital Libraries', university of Antwerp, October 2015
Keynote talk at the Web Science Summer School, Singapore, 8 December 2014. Today we see the rise of Social Machines, like Twitter, Wikipedia and Galaxy Zoo—where communities identify and solve their own problems, harnessing commitment, local knowledge and embedded skills, without having to rely on experts or governments.
The Social Machines paradigm provides a lens onto the interacting sociotechnical systems of our hybrid digital-physical world, citizen-centric and at scale—emphasising empowerment and sociality in a world of pervasive technology adoption and automation.
This talk will present the Social Machines paradigm as an approach to social media analytics and a rethinking of our scholarly practices and knowledge infrastructure.
This is a presentation by the Division of Information and Technology Studies, Faculty of Education, The University of Hong Kong. Advances in information and communication technology, especially the rapid developments in social technology such as wikis, blogs, social bookmarking, etc. have opened up new opportunities as well as challenges to education in schools as well as human resource development and training in public and business sectors. In the seminar, a group of experts introduce recent developments in learning technology and how these have been applied in different educational and human resource development contexts internationally and locally.

In the world of digital literacies, liaison and instructional librarians are increasingly coming to terms with a new term: algorithmic literacy. No matter the liaison or instruction subjects – computer science, sociology, language and literature, chemistry, physics, economics, or other – students are grappling with assignments that demand a critical understanding, or even use, of algorithms. Over the course of this session, we’ll discuss the term ‘algorithmic literacies,’ explore how it fits into other digital literacies, and see why it as a curriculum might belong at your library. We’ll also look at some examples of practical pedagogical methods you can implement right away, depending on what types of AL lessons you want to teach, and who your patrons are. Lastly, we’ll discuss how librarians should view themselves as co-learners when working with AL skills. This session seeks to bring together participants from across the different libraries, with diverse missions/vision/mandates, to explore ways we can all benefit from teaching AL. If time permits, we may discuss how text and data librarians (functional specialists) can support the development of this curriculum.
Spatial Data Infrastructure (SDI), communities and social media are three different terms. What do they have in common? At first all these terms are very modern and trendy
now. They are very often used not only in technical publications but these words and collocations are also used by the public. It is possible to say that primarily social media could
be described as buzzword (fashion word and vogue word).
Information and communication technologies (ICT) are simply technologies arising fromscientific and technological progress in computer sciences, electronics andtelecommunications. They enable us to process, store, retrieve and disseminate valuableinformation in text, sound and video form. In an increasing interconnected world, brought about by the application of technological advances to all sectors of society, quality education necessitates active and innovative exploration to maximize the benefits of ICT and developand maintain the partnerships that use of ICT in education requires. This calls for re-conceptualising and restructuring the educational enterprise, so as to confront thetechnological challenges of this millennium. With rapid changes within society and radical transformations in the way people acquire knowledge, new teaching paradigms arerequired, ones that tune educational systems to modern times and ensure quality trainingfor large numbers of persons.
Seminar at CSAIL, MIT, Cambridge, Mass. Date: Friday October 30, 2015. Time: 4:00 pm - 5:00 pm, Location: D463 (Star)
Abstract:
Today we are witnessing several shifts in scholarly practice, in and across multiple disciplines, as researchers embrace digital techniques to tackle established research questions in new ways and new questions afforded by digital and digitized collections, approaches, and technologies. Pervasive adoption of technology, coupled with the co-creation of new social processes, has created a new and complex space for scholarship where citizens both generate and analyse data as they interact at the intersection of the physical and digital. Drawing on a background in distributed computing, and adopting the lens of Social Machines, this talk discusses current activity in digital scholarship, framing it in its interdisciplinary settings.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
