What is the name of the point at which the two halves of duplicated chromosomes are connected?
Ah, that's a happy little detail called the centromere, friend. It's like the glue that holds the duplicated chromosomes together, ensuring they are distributed accurately when cells divide. Just a tiny touch of detail that plays a big role in the beautiful process of cell division.

Why is it important that cells have half the number of chromosomes as body cells?
In sexual reproduction, each parent contributes a sex cell with half as many chromosomes as the normal cells. The two sex cells combine and the zygote will have the proper total of chromosomes. In this way, the offspring inherit genetic information from both parents.
What 3 things homologous chromosomes have in common?
Homologous chromosome have gene of same character.
Are chromosomes visible when stained?
Chromosomes can be seen using a light microscope (LM). Mitotic cells can be easily visualised. The study of chromosomes using LM is termed Karyology, the chromosomes are prepared by a variety of techniques and analyses can be performed.
How are most animals classified based on their symmetry?
Animals are classified based on their symmetry as either radial or bilateral. Radial symmetry means the animal can be divided into equal halves in multiple ways around a central point, like a starfish. Bilateral symmetry means the animal can be divided into two equal halves along a single plane, like a human.
What is the difference between Chiasma and Chiasmata?
Chiasma refers to the physical site of crossover between homologous chromosomes during meiosis, facilitating genetic recombination. Chiasmata are the visible manifestations of chiasmata, appearing as X-shaped structures that hold homologous chromosomes together before they separate during meiosis.
Chromosomes are called what once they have duplicated in preparation for division?
During prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. ... Because each chromosome was duplicated during S phase, it now consists of two identical copies called sister chromatids that are attached at a common center point called the centrome or chromosomal duplications
What do symmetric mean?
Bilateral symmetry means you can divide the shape into two halves, and the halves would be congruent. Radial symmetry means all the parts that are connected to a common point are congruent.
Why do karyotypes always show chromosomes at the point when cell division is about to occur?
They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.
three point one four times twelve halves squared?
11111111
What point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
How many miniets in a nrl game?
2x 40min halves = 80. then theres 'golden poin't 2xtimes 5 mins halves (unless one team scores a point)
When a line of symmetry divides an image every point on one side of the line has a corresponding point in the other side?
A line of symmetry is a line that divides an image into two identical halves, such that each point on one side of the line has a corresponding point directly opposite it on the other side. This correspondence ensures that the two halves are mirror images of each other, maintaining the same shape and size. In essence, if you were to fold the image along the line of symmetry, the two halves would align perfectly.
What two chromatids of chromosome are attached at a point?
x and y chromosomes
For an inequality whose boundary is a hyperbola you should pick a test point that is located?
in between its two halves
What is the star point of a CT?
The term, 'star point', refers to the common point of connection for the three windings of a star-connected (wye-connected) transformer connection. The star point is usually earthed (grounded) and provides the neutral point of the connection.
What are the release dates for Turning Point - 2000 Stay Connected?
Turning Point - 2000 Stay Connected was released on: USA: 11 October 2009
What are the three ways chromosomes can cause mutations?
point mutation, insertion and deletion
