Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Tiny bodies, big inheritance role.
Chromosomes are darkly stained, small bodies in the nucleus that determine the mechanism of inheritance. In 1902, W.S. Sutton and T. Boveri proposed that chromosomes are the physical structures acting as messengers of heredity. They are best seen during metapha...
↳ Chromosomes are the physical carriers of hereditary information.
DNA plus proteins equals chromosome.
In eukaryotic organisms, DNA molecules in the nucleus combine with proteins, mainly histones, to form chromosomes. The makeup of a chromosome is considered to be highly coiled DNA. Each species has a characteristic number of chromosomes in each cell.
↳ Chromosomes are highly coiled DNA wrapped around histone proteins.
Same species, same number.
The number of chromosomes in cells of different species is variable. In general, all somatic cells of all individuals of the same species possess the same number of chromosomes. Both size and shape of chromosomes differ in different species of fish.
↳ Chromosome number is species-specific and constant within a species.
Chromosomes are darkly stained, small bodies in the nucleus that determine the mechanism of inheritance. They are made of highly coiled DNA combined with histone proteins and occur in pairs in diploid organisms. The numb...

17 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Who proposed in 1902 that chromosomes are the physical structures acting as messengers of heredity?
BeginnerW.S. Sutton and T. Boveri
The source states that in 1902, W.S. Sutton and T. Boveri suggested that chromosomes were the physical structures which act as messenger of heredity.
During which stage of cell division can chromosomes be clearly seen after specific staining?
BeginnerMetaphase
The source mentions that after specific staining, chromosomes can be clearly seen during mitotic cell division particularly during the metaphase.
What is the term for the two chromosomes that form a pair?
BeginnerHomologues
The source defines the two chromosomes that form a pair as homologues.
In humans, how many chromosomes are present in each somatic cell?
Beginner46
The source states that each cell in every human being has 46 chromosomes consisting of 23 different pairs.
