Answer:
Enzymes
Explanation:
The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.
During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.
Answer:
recombinant DNA
A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA
Explanation:
Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.
Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.
This single DNA is known as Recombinant DNA
Foodborne illness is the contamination that results from the spread of bacteria from meat to vegetable. Various types of pathogenic micro-organisms get access to food, which is rich in nutrients and allows bacteria to flourish. When such contaminated foods are eaten, they cause foodborne illness.
Answer:
Answer B.
Explanation:
Biological Fitness, also called darwinian fitness, means the ability to survive to reproductive age, find a mate, and produce offspring. basically, the more offspring an organism produces during its lifetime, the greater its biological fitness.
