The document summarizes the stages of mitosis. It begins with a cell entering prophase where its duplicated chromosomes condense. In metaphase, the chromosomes migrate to the center of the cell. During anaphase, the sister chromatids separate from each other. Telophase concludes mitosis as the chromosomes decondense and a nuclear membrane reforms around each daughter cell. Mitosis produces two daughter cells that are genetically identical to the parent cell.

Cells are the basis of life—the basic structural unit of living things. Molecules such as water and amino acids are not alive but cells are! All life is comprised of cells of one type or another.
One of the hallmarks of living systems is the ability to maintain homeostasis, or a relatively constant internal state. The cell is the first level of complexity able to maintain homeostasis, and it is the unique structure of the cell that enables this critical function.
In this section of the course, you will learn about the cell and all the parts that make it functional. You will also focus on the cell membrane, which is the structure that surrounds the cell and separates its internal environment from the external environment. It is a critical component because it controls what can enter and exit the cell. This section will also describe how cells reproduce to maintain homeostasis.Cells are the basis of life—the basic structural unit of living things.

This is a Presentation describing the structure and different functions of many cell organelles. This describes cells, types of cells, prokaryotic cells, eukaryotic cells, cell membrane, cytoplasm, mitochondria, nucleus, nucleolus, vacuoles, endoplasmic reticulum, Golgi apparatus, ribosomes, lysosomes, cell wall, and plastids.
The cell is the basic unit of life. All organisms are made up of cells (or in some cases, a single cell). Most cells are very small; most are invisible without using a microscope. Cells are covered by a cell membrane and come in many different shapes. The contents of a cell are called the protoplasm.
The cell is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.
All living things are made of organized parts, obtain energy from their surroundings, perform chemical reactions, respond to their environment, grow and develop, change with time, and reproduce
All organisms are made of cells
All cells are produced from other cells (all cells arise from pre-existing cells by cell division)
The cell is the most basic unit of life
At the end of this session, the student should be able to:
a. Describe the representative functional systems of the cell and discuss their potential roles.
b. Describe the types of locomotion in non-muscle cells and discuss their mechanisms.

The study of the cell cycle focuses on mechanisms that regulate the timing and frequency of DNA duplication and cell division. As a biological concept, the cell cycle is defined as the period between successive divisions of a cell. During this period, the contents of the cell must be accurately replicated.
The cell cycle is regulated by cyclins and cyclin-dependent kinases.
How long is one cell cycle?
Depends. Eg. Skin cells every 24 hours. Some bacteria every 2 hours. Some cells every 3 months. Cancer cells very short. Nerve cells never.
Programmed cell death:
Each cell type will only do so many cell cycles then die. (Apoptosis)

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. • A cell enters mitosis, its duplicated chromosomes condense
into rod- shaped bodies (prophase)
• As mitosis progresses, the chromosomes migrate to the
equatorial plane of the cell (metaphase)
• In mitosis, the centromere that holds the sister chromatids of
a duplicates chromosomes together splits, and the sister
chromatids separate (or disjoin) from each other (anaphase)
• As mitosis comes to en end, the chromosomes decondense
and a nuclear membrane reforms around them (telophase)
• Each daughter cell produced by mitosis and cytokinesis has
the same set of chromosomes; thus daughter cells are
genetically identical.
3. • During mitosis, the chromosomes
shorten and thicken
• They ‘condense’ out of the
chromatin network and individual
chromosomes ‘decondens’ the
chromatin network is re-formed.
• When mitosis begins each
chromosome has already been
duplicated, and the duplicated
called sister chromatids, they
intimately associated with each
other and are joined at the
chromosome’s centromere.
• Microtubules: Distribution of
duplicated chromosomes to the
daughter cells is organized and
executed by microtubules, are
components of the cytoskeleton.
These fibers composed of
proteins (tubulins), attached to the
chromosomes and move them
about within the dividing mother
cell.
4. • The microtubules assemble into a
complex array called the spindle.
Formation of the spindle depends on
microtubules organizing centers
(MTOCS), are formed in the
cytoplasm usually near to the
nucleus.
• The MTOCS are differentiated into
small organelles called centrosomes.
Each centrosomes contains two
barrel shaped centrioles.
• Pericentriolar material: A
centrosome consists of two barrel-
shaped centrioles embedded in a
matrix of proteins known as the
pericentriolar material (PCM). The
PCM serves as a platform
for protein complexes that regulate
organelle
Spindle
fibers
5. • S is the period in which
the chromosomes are
duplicated, an events
that require DNA
synthesis, to which the
label “S” refers.
• The M phase in the cell
cycle is the time, when
the mother cell actually
divides. Has usually
two components:
(1) Mitosis
(2) Cytokinesis
The label “M” refers to
the term mitosis, is
derived from Greek
word for thread.
• The G1 and G2 phase
are “gaps” between the
S and M phases.
This cycle is 24 hours long, a series of phases
that collectively form the CELL CYCLE
6. • Interphase: during this period individual chromosomes cannot
be seen, which may be quite lengthy. Is the phase of the cell
cycle in which a typical cell spends most of its life. During
interphase, the cell gets itself ready for mitosis or meiosis.
• Prophase: Prophase is the first stage of cell division in both
mitosis and meiosis. Beginning after interphase, DNA has
already been replicated when the cell enters prophase. The main
occurrences in prophase are the condensation of the chromatin
and the disappearance of the nucleolus.
• Metaphase: Chromosomes aligned at metaphase plate halfway
between the poles. Spindle microtubules attached to the
kinetochores.
• Anaphase: Sister chromatids of duplicated chromosomes are
separated from each other during this phase, this separation is
accomplished by shortening the microtubules attached to the
kinetochores.
• Telophase: The process that separates the duplicated genetic
material carried in the nucleus of a parent cell into two identical
