So, the correct answer is Sub-metacentric i.e option (d).
Which chromosomes are J shaped or L shaped?
The metacentric chromosomes appear to be V-shaped. sub- metacentric chromosomes appear to be L-shaped, the telocentric chromosome appears to be like I-shaped and the acrocentric chromosome appears to be J-shaped.
What are the shapes of chromosome?
Chromosomes have generally three different shapes, viz., rod shape, J shape and V shape. These shapes are observed when the centromere occupies terminal, sub terminal and median position on the chromosomes respectively. Chromosome size is measured with the help of micrometer at mitotic metaphase.
What is the shape of telocentric chromosome?
The centromere of a telocentric chromosome is located at the terminal end of the chromosome, and p arms is barely visible. The shape of telocentric chromosome is similar to the letter “i” during anaphase.
Which type of chromosome appears L shape during anaphase?
Submetacentric chromosomes are those whose centromere is located slightly away from the centre. They appear L-shaped during anaphasic movements.
What is J shaped chromosome?
The chromatids moving towards opposite poles appear to be of various shapes like V-shaped (metacentric chromosomes), J-shaped (submetacentric chromosomes) or I-shaped (telocentric chromosomes), depending on the position of the centromere.
What is called the J shaped chromosome?
2. Submetacentric Chromosomes. The chromosomes in which the centromere is slightly away from the middle point so that its two arms become unequal in length are called submetacentric. These are L shaped or J shaped.
What are the 4 types of chromosomes?
Chromosomes can be classified into 4 types based on the length of the chromosomal arms and the position of the centromere.
- Sub metacentric chromosomes.
- Acrocentric chromosomes.
- Telocentric chromosomes.
- Metacentric chromosomes.
What are the three shapes of a chromosome?
There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric.
Why is it called anaphase?
anaphase Add to list Share. Anaphase is a stage in cell division that happens towards the end of mitosis. During anaphase, chromosomes move away from each other. … Anaphase was first coined in German, from the Greek ana-, “back.”
What shape would a Metacentric and Submetacentric?
Metacentric chromosomes produce V-shaped daughter chromosomes, submetacentric appear J-shaped and acrocentric form I-shapes. When creating karyotypes, the position of the centromere is used to find matching pairs, as it can be very specific.
What is Metacentric Submetacentric and Acrocentric?
Submetacentric chromosomes have the centromere placed visibly off-center. Acrocentric and telocentric chromosomes are defined as having the centromere near and at the end of the chromosome, respectively.
What is the meaning of Submetacentric?
Definition of submetacentric
: having the centromere situated so that one chromosome arm is somewhat shorter than the other.
Which is not true for anaphase?
Reformation of organelles is a key event of telophase. This stands not true for anaphase and hence this is the correct answer.
Which of the following chromosomes appear V shaped during anaphase stage of cell division?
Metacentric chromosomes have the centromere located at or near the middle of the structure, resulting in two arms of equivalent (or nearly so) length. These chromosomes appear V-shaped when observed during anaphase.
What are Bivalents in meiosis?
During the prophase of meiosis I, homologous chromosomes pair and form synapses. The paired chromosomes are called bivalents. The bivalent has two chromosomes and four chromatids, with one chromosome coming from each parent.
