Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.
Answer:
Explanation:
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[1] These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.[2]
Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality degrees and comfort ratio of greenhouses, such as air temperature, relative humidity and vapour-pressure deficit, in order to reduce production risk prior to cultivation of a specific crop.
Answer:
I would say Phosphate Groups.
Explanation:
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
Plant cells have a rectangular shape and a cell wall, while animal cells have a circular shape and no cell wall
Explanation:
2) E) ribosome .
3) c) cytoskeleton: The cytoskeleton is a series of fibers made from proteins. It provides structure to the cell and gives it its shape it its shape.
4) a) chloroplast
