An eclipse occurs when one celestial body passes in front of another and casts a shadow. A solar eclipse happens when the moon passes between the earth and sun, casting its shadow on earth. There are three types of solar eclipses: total, partial, and annular. A total solar eclipse can only be seen within the moon's dark umbral shadow. A lunar eclipse occurs when the earth passes between the sun and moon, casting its shadow on the moon. The three types of lunar eclipses are: total, partial, and penumbral. Eclipses can only occur during a new moon for a solar eclipse or full moon for a lunar eclipse.
A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.

A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.

Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
9. What is an eclipse?
• An eclipse occurs any time something
passes in front of the Sun, blocking its light.
This can be the Earth or the Moon.
10. Types of eclipses
• Lunar Eclipse- When the Earth casts a shadow
on the moon, causing the moon to go dark.
Earth comes between the Sun and the Moon
and casts a shadow on the Moon (Full Moon)
• Solar Eclipse- When the Moon casts a shadow
on the Earth, causing the sun to go dark.
The Moon comes between the Sun and Earth and
casts a shadow on part of Earth (New Moon)
11. • Umbra – The dark inner portion of the
shadow cone.
• Penumbral – the lighter outer portion of
the shadow.
15. Partial Solar Eclipse – Visible if you are in the
penumbra of the shadow. Only some of the Sun will
be blocked by the Moon
16. Annular Eclipse – occurs when the moon is farthest
from the Earth in its orbit. This makes the moon look
smaller, so during the eclipse you see an outer ring of
light from the Sun.
17. Here is an animation showing a total solar eclipse
Remember that it is not safe to stare at a solar eclipse !!!
18. This animation shows that the moon creates a small shadow which
Only allows certain areas of the earth to see a total solar eclipse.
19. Lunar Eclipse
The diagram shows
That the moon is covered by the
Earth’s shadow, which makes this
Eclipse safe to look at.
Notice the moon sometimes turns
red
When totality occurs.
20. If you are in the umbra of the shadow, you will see a total eclipse.
If you are in the penumbra of the shadow, you will have a partial eclipse
24. Penumbral Lunar Eclipse – When the moon passes
only through the penumbra, or partial shadow. They
are barely visible.
25. This is an animation showing a total lunar eclipse from start
To finish.
26. Why Don’t We See Lunar
Eclipses More Often?
• Lunar eclipses don’t happen every month
because the Moon’s orbit is tilted. So,
during most months, the Moon is above or
below the Earth.
27. Let’s Answer!
• How does solar eclipse happen?
• What are the different types of solar
eclipse?
• In what phase of the moon does a solar
