The plasmid is an extrachromosomal DNA molecule that is not part of the bacterial genome. Plasmids carry genes that benefit the survival of the organisms. For example, antibiotic resistance. The plasmid is transmitted from one bacterium to another through conjugation. Transfer of genetic material is the mechanism of horizontal gene transfer and plasmid are considered as part of mobilome, unlike viruses where plasmids are nacked DNA.
For plasmids to replicate independently with cell must possess stretch of DNA that acts as the origin of replication. Self-replicating of the plasmid is called replicon.
Resposta:
Ecotoxicologia
Explicação:
A ecotoxicologia é o estudo das interações que os seres vivos possuem não só entre si, mas também com o ambiente em que esses seres vivem.
Estudos de ecotoxicologia buscam compreender os diferentes tipos de reações causadas por substâncias químicas, bioquímicas e os processos biológicos que podem ocasionar essas reações, considerando a sensibilidade que diferentes organismos possuem a essas substâncias e os potenciais toxicológicos delas.
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
Explanation:
Answer:
It is as potential for the rapid growth in the future.
Explanation:
The age pyramid structure or population pyramid may be defined as the graphical distribution of the different age group of the population. Different age groups are pre-reproductive, reproductive and post reproductive.
Different age pyramids are expanding population ( pyramid shape) decline population ( urn shape) and stable population. The age group of the pyramid population determines the potential or the ability of the rapid growth of the country in the future.
