Give 3 effects of antibiotics that they can have on bacteria. Max 3 sentences
Antibiotics can inhibit bacterial cell wall synthesis, preventing the bacteria from maintaining their structure and causing cell death.
They can also interfere with protein synthesis, stopping bacteria from producing essential proteins needed for survival.
Additionally, antibiotics can disrupt bacterial DNA replication, hindering the ability of bacteria to reproduce and spread.
Gene duplication: Mechanism and significance for evolution
Mechanism:
Gene duplication occurs when a DNA segment is copied, resulting in two identical genes in the genome. This can happen due to DNA replication errors, unequal crossing-over during meiosis, or retrotransportation.
Significance for Evolution:
Gene duplication is evolutionarily significant because it creates genetic redundancy, allowing one copy to mutate without losing the original function. This can lead to new functions or divided roles, promoting adaptation and diversity.
