Chromosome in which centromere is close to one end which result in short arm being very short is which type of chromosome?
**Core Concept**
The question is testing the understanding of chromosome morphology and the location of the centromere, a crucial region for chromosome segregation during cell division. Chromosomes with a centromere close to one end are characterized by a short arm that is significantly shorter than the long arm.
**Why the Correct Answer is Right**
Chromosomes with a centromere located near one end are classified as acrocentric chromosomes. This type of chromosome has a short arm (p arm) that is significantly shorter than the long arm (q arm). The location of the centromere close to one end results in the short arm being very short. Acrocentric chromosomes are typically found in the human genome and are involved in various genetic processes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the characteristic of a chromosome with a centromere close to one end.
**Option B:** This option is incorrect because it describes a metacentric chromosome, which has a centromere located near the center, resulting in approximately equal-length arms.
**Option C:** This option is incorrect because it does not accurately describe the characteristic of a chromosome with a centromere close to one end.
**Option D:** This option is incorrect because it is a distractor and does not describe the characteristic of a chromosome with a centromere close to one end.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that acrocentric chromosomes are involved in various genetic processes, including the formation of the nucleolus organizer region (NOR) and the production of ribosomal RNA.
**Correct Answer:** C. Acrocentric.
