Study Notes

Cellular Reproduction

Telomeres are repetitive DNA sequences (TTAGGG in humans) that protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes.

Plant Growth

Hormones, particularly auxins, dictate growth in plants.

Chromosome Number

In somatic cells of a species, the characteristic chromosome number is diploid (2n), meaning two sets of chromosomes, one inherited from each parent.

Olea Europaea (Olive Tree)

Olea europaea, the olive tree, has 46 chromosomes per cell.

Meiosis

Meiosis is a type of cell division that reduces the number of chromosomes by half, producing four non-identical daughter cells, each with a unique combination of genetic traits.
The role of meiosis in the cell cycle is to produce gametes (sperm or egg cells) for sexual reproduction.

Telomeres and Their Function

Telomeres function as a protective cap, preventing the loss of genetic information during DNA replication and protecting the chromosome from degradation.
