Telocentric chromosomes:Herein, the centromere is present at the terminal end of the arm of the chromosome; as a result, there is a shorter arm, and the other is a long arm. Acrocentric chromosome:Herein, the centromere is placed near to chromosomal arm end, making the p arm very short ...

An autosome refers to any chromosome not considered a sex chromosome. Autosomes are mainly associated with the various metabolic functions of the cell. They occur in pairs in somatic cells and singly in sex cells (gametes). In humans, a somatic cell normally contains 23 pairs of chromosomes (...

Explain what homologous chromosome pairs are? What are homologous chromosomes? Which human cells do...
A root word is the most basic form of a word that cannot be further divided into meaningful segments. Root words are used to form new words by adding letters at the beginning (i.e., a prefix) and/or the end (i.e., a suffix). For example, the word “unfaithful” is made up of...
This is known as the forespore – A section of the cell containing chromosome is engulfed by a membrane as the peptidogycan is synthesized. Stage IV-V: Cortex and Coat assembly - Synthesis of the peptidoglycan cortex followed by formation of proteinaceous spore coat: In this stage, the ...

beingsex chromosomes(XX for females, XY for males). Each homologous pair consists of one chromosome inherited from each parent, contributing to genetic diversity. Understanding homologous chromosomes is crucial for grasping concepts likegenetic variation, inheritance patterns, and the role of alleles in...
During an inversion, regions of a chromosome are broken at two sites - their breakpoints - and are reinserted in a backward order. What are the effects of chromosomal inversions? An inversion can disrupt a gene - resulting in different gene expression or a faulty or non-working protein - or...
When an intersex child is born with the XX chromosome and has the ovaries of a female but the external genitalia of a male, the individual may have been exposed to higher-than-normal levels of male hormones while in the womb. In some cases, the individuals do not know they have a ...
