Eduqas A Level Biology mitosis and meiosis revision guide: Key concepts and processes of cell division explained for students. Covers chromosome structure, ploidy, cell cycle stages, and detailed steps of mitosis.
09/07/2022
758
This page delves into homologous chromosomes, ploidy levels, and introduces the cell cycle for Eduqas A Level Biology students.
Key concepts covered:
Definition: Diploid refers to having two complete sets of chromosomes, symbolized as 2n. In humans, the diploid number is 2n = 46.
Highlight: Homologous chromosomes are matching pairs that are identical in size and shape, carrying genes for the same characteristics but potentially different alleles.
Vocabulary: Ploidy level - the number of complete sets of chromosomes in an organism.
Example: Human body cells are diploid (2n), while gametes are haploid (n).
This page focuses on the process of mitosis and its stages, crucial for Eduqas A Level Biology students studying cell division.
Key points covered:
Definition: Mitosis is a type of cell division producing two genetically identical daughter cells.
Highlight: Interphase is the longest phase of the cell cycle, involving significant metabolic activity and DNA replication.
Vocabulary: S phase - the part of interphase where DNA replication occurs (synthesis phase).
Example: During prophase, chromosomes condense and become visible, while the nuclear envelope disintegrates and the spindle forms.
This page introduces fundamental concepts related to chromosomes and cell division in Eduqas A Level Biology.
Key points covered:
Definition: A chromosome is a long, thin structure of DNA and protein in the nucleus of eukaryotic cells, carrying genes.
Vocabulary: Chromatid - one of two identical copies of a chromosome, joined at the centromere, prior to cell division.
Highlight: Chromosomes only become visible when chromatin condenses prior to cell division, after DNA replication.
Example: Humans have 46 chromosomes in their body cells, but this number varies among different species.
