The correct answer is: Replacement of defective genes with normal genes
Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
Answer:
Increased fossil fuel use has increased atmospheric carbon dioxide.
Explanation:
Burning fossil fuels increases the amount of CO₂ in air, which is unhealthy.
Answer:
The given blank can be filled with acquisition.
Explanation:
An unconditioned stimulus provokes the unlearned response and an unconditioned response is the naturally taking place reaction. A neutral stimulus is illustrated as the stimulus that prior to conditioning do not generate any kind of response.
A type of learning wherein a subject begins to react towards neutral stimulus as it would perform with another stimulus by acquiring the path of associating the two stimuli is termed as classical conditioning.
An acquisition can be illustrated as the time of learning in classical conditioning where an individual begins to associate a neutral stimulus with an unconditioned stimulus that further permits the neutral stimulus to begin possessing the conditioned response.
Not always because there could be birth defects, mutations, or other variables.
