Transcription

The process of copying a gene's DNA sequence into a messenger RNA (mRNA) molecule. This mRNA then carries the genetic information to the ribosomes, where proteins are synthesized.

Mutation

A permanent change in the DNA sequence of an organism. Mutations can be caused by errors in DNA replication or by exposure to mutagens such as radiation or chemicals.

Evolutionary evidence

This refers to the change in the frequency of alleles (genes) in a population over time. This is driven by factors like natural selection, genetic drift, and gene flow.

Types of evidence for evolution?

Fossil record, anatomical homology, molecular homology, biogeography, and direct observation are all examples of this evidence.

What is sexual reproduction in plants?

This type of reproduction involves the fusion of two gametes (sex cells), a sperm and an egg, to produce a zygote, which develops into a new organism.

What is double fertilization in flowering plants?

A process that involves the fusing of a sperm cell with two polar nuclei within the embryo sac of a flowering plant. One fusion results in the formation of the zygote (2n), which will develop into the embryo, while the other fusion gives rise to the endosperm (3n), a nutritive tissue that nourishes the developing embryo.

Study Notes

Evidence Supporting Evolution

  • Fossil Record: Fossils reveal a chronological sequence of life forms, demonstrating evolutionary change over time. Transitional fossils show intermediate characteristics between ancestral and descendant species
  • Comparative Anatomy: Similar structures (homologous) in different species suggest shared ancestry despite functional differences. Vestigial structures, like the human appendix, are remnants of features crucial to ancestral species.
  • Comparative Embryology: Early embryonic stages of different species can exhibit remarkable similarities, hinting at a common evolutionary origin.
  • Biogeography: Distribution patterns of species across the globe reflect their evolutionary history and the process of speciation in different environments.
  • Molecular Biology: Similarities in DNA and protein sequences among organisms provide evidence for common ancestry. Closely related species share more similar DNA sequences than distantly related ones.

Transcription and Mutation

  • Transcription: The process of copying genetic information from DNA to RNA. This RNA then directs the synthesis of proteins.
  • Mutation: A permanent change in a gene or chromosome. Mutations can be spontaneous or induced by environmental factors. They introduce variations in the genetic material which are crucial for evolution.
