What is telocentric chromosome?
A metacentric chromosome has two equal arms because the centromere can be found in the median position. A telecontric chromosome, on the other hand, is like a straight rod. Its centromere is in the terminal position.
When DNA is copied to form chromosomes that have 2 sister chromatids this is called DNA .?
Each chromosome has two arms, labeled p (the shorter of the two) and q (the longer). The p arm is named for "petite" meaning 'small'; the q arm is named q simply because it follows p in the alphabet. (According to the NCBI, "q" refers to the French word "queue".) They can be Metacentric A chromosome is metacentric if its two arms are roughly equal in length. In some cases, a metacentric chromosome is formed by balanced Robertsonian translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome. Submetacentric If arms' lengths are unequal, the chromosome is said to be submetacentric Acrocentric If the p (short) arm is so short that is hard to observe, but still present, then the chromosome is acrocentric (The "acro-" in acrocentric refers to the Greek word for "peak."). In an acrocentric chromosome the p arm contains genetic material including repeated sequences such as nucleolar organizing regions, and can be translocated without significant harm, as in a balanced Robertsonian translocation. The domestic horse genome includes one metacentric chromosome that is homologous to two acrocentric chromosomes in the conspecific but undomesticated Przewalski's horse. This may reflect either fixation of a balanced Robertsonian translocation in domestic horses or, conversely, fixation of the fission of one metacentric chromosome into two acrocentric chromosomes in Przewalski's horses. A similar situation exists between the human and great ape genomes; in this case, because more species are extant, it is apparent that the evolutionary sequence is a reduction of two acrocentric chromosomes in the great apes to one metacentric chromosome in humans Telocentric A telocentric chromosome's centromere is located at the terminal end of the chromosome. Telomeres may extend from both ends of the chromosome. For example, all mouse chromosomes are telocentric Holocentric With holocentric chromosomes, the entire length of the chromosome acts as the centromere. Examples of this type of centromere can be found scattered throughout the plant and animal kingdoms with the most well known example being in the worm, Caenorhabditis elegans.
Is chromosome Y an acrocentric chromosome?
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
What are P and Q arms of a chromosome?
The p arm is the shorter arm of the chromosome. The q arm is the longer arm. For chromosomes which are metacentric, the arms tend to be the same length. For submetacentric, acrocentric, or telocentric, the p and q arms show clear differences in length- and thus are classified accordingly.
What does deletion chromosome consists of?
There is no 'deletion chromosome'. You mean chromosome deletion, and it is a phenomenon where a chromosome disappears from cell's genetic layout.

What is the center of a chromosomes called?
The center of a chromosome is a centromere.

What is the possessive noun for illustration?
The possessive form for the noun illustration is illustration's.
How do you arrange chromosomes in a karyotype?
Homologous chromosomes are identified by two main characteristics viz, size and position of the centromere. Homologous chromosomes always have the same size. According to the position of the centromere, they may be acrocentric, metacentric, sub-metacentric and telocentric.
