What is meant by chromosome explain its type s with diagram
Answers
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
four types of chromosome
Metacentric Chromosomes
Metacentric chromosomes have the centromere in the center, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric.
Submetacentric Chromosomes
Submetacentric chromosomes have the centromere slightly offset from the center leading to a slight asymmetry in the length of the two sections. Human chromosomes 4 through 12 are submetacentric.
Acrocentric Chromosomes
Acrocentric chromosomes have a centromere which is severely offset from the center leading to one very long and one very short section. Human chromosomes 13,15, 21, and 22 are acrocentric.
Telocentric Chromosomes
Telocentric chromosomes have the centromere at the very end of the chromosome. Humans do not possess telocentric chromosomes but they are found in other species such as mice.
Answer:
The compactly packed structure of chromatin is called chromosome.
types: Metacentric- equal size of arms and V shaped,
Submetacentric- one long and one short arm and L shaped ,
Acrocentric- one very large arm and one very short arm and J shaped,
Telocentric- centromere reach the end, so appear as only one long arm and I shaped.
