Answer:

The correct answer is "Mutate or remove the Shine-Dalgarno sequence on the mRNA".

Explanation:

The Shine-Delgarno sequence is a fragment of bacterial and archaeal messenger RNA that helps to recruit the messenger RNA to the ribosome to initiate protein synthesis by translation. Mutating  or removing the Shine-Dalgarno sequence on the mRNA will prevent translation of a particular prokaryotic mRNA. Therefore, this is a reasonable experimental strategy to achieve this effect without targeting the ribosome, but the prokaryotic mRNA.

Alex

The endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat.  It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.

Multicellular gametophytes are the product of spores from ____​
jolli1 [7]

Answer:

In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.

Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.

In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.

Advocard [28]

Answer:

Nervous systems become clearly unique in their communication properties only at the tissue and organ level, where billions of cells can work together as an intricately organized interconnected circuit. It is through the organization of cells in these neural circuits that the brain supports the great diversity of animal behavior, up to and including human consciousness, cognition, and emotion.

 

Explanation:

Communication, the effective delivery of information, is essential for life at all scales and species. Nervous systems (by necessity) can adapt more specifically between biological tissues for the high speed and complexity of the information transmitted, and therefore, the properties of neural tissue and the principles of its circuit organization can illuminate the capabilities and limitations of biological communication. Here, we consider recent developments in tools to study neural circuits with special attention to defining neural cell types using input and output information flows, that is, how they communicate. Complementing the approaches that define cell types by virtue of the properties of the genetic promoter / enhancer, this communication-based approach to define cell types operably by the structure and function of linkages of input / output relationships (E / S), solves the difficulties associated with defining unique genetic characteristics. , leverages technology to observe and test the importance of precisely these I / O ratios in intact brains, and maps processes through which behavior can adapt during development, experience, and evolution.
