What is the difference between replicated and unreplicated chromosomes?
a unreplicated chromosome has one DNA molecule; a replicated chromosome has two identical DNA molecules (sister chromatids) attached at the centromere. … HOMOLOGOUS chromosomes are chromosomes of the same type.
What is the difference between a non duplicated chromosome and a chromatid?
Chromosomes are the microscopic entities in living cells that contain the genetic information pertaining to the organism as a whole. … The difference between a duplicated chromosome and a chromatid, strictly speaking, is that a chromosome contains two chromatids that are joined at a structure called a centromere.
What does it mean when a chromosome is duplicated?
The term “duplication” simply means that a part of a chromosome is duplicated, or present in 2 copies. This results in having extra genetic material, even though the total number of chromosomes is usually normal.
What is the difference between replicate and duplicate?
Duplicate means to make an exact copy and can also be used as an adjective and a noun. Replicate means to reproduce something, and can also be used as an adjective and a noun.
Are chromosomes replicated or unreplicated after mitosis?
To make this happen, replicated chromosomes condense (prophase), and are positioned near the middle of the dividing cell (metaphase), and then each of the sister chromatids from each chromosome migrates towards opposite poles of the dividing cell (anaphase), until the identical sets of unreplicated chromosomes are …
What are Nonsister chromatids?
Non-sister chromatids are chromatids of homologous chromosomes. … These chromatids contain the exact same genes and the exact same alleles – the chromatids are exact copies of each other.
What is the difference between homologous and non homologous chromosomes?
The primary difference between these two chromosomes – homologous and non-homologous lies in their constituency of alleles. Homologous chromosomes consist of alleles of the same gene type found in the same loci unlike non-homologous chromosomes, which constitute alleles of varying gene types.
What process ends with unreplicated chromosomes?
Interphase preceding Meiosis
Prior to the S phase, each homologous pair of chromosomes (one paternal and one maternal chromosome of the same type) are unreplicated.
