The structure and function of specialised cells in multicellular organisms are different. Explain why this is possible if they a

NISA [10]4 years ago

Answer:

<h2>Differential gene expression </h2>

Explanation:

1. Cell specialization occurs due to the differential gene expression, it is the process which is responsible for the production of cells with different traits at different positions and at different time. This process changes cells  from simple to more specialized in  both structure as well as in function. This is all due to the differential gene expression where all cells beside containing the same gene, express different genes in different cells.

2. Cell differentiation is very important among almost all multicellular organisms. This process results in the  formation of a complex organism with different types of tissues and cells from a zygote.

Gene expression in eukaryotes can be regulated at many different levels. List the different levels of regulation, and explain wh
Aneli [31]

Answer:

Transcription, mRNA (processing, transport, localization and stability), translation.

Explanation:

  • Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
  • mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
  • In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Plant transgenic technology is important for the introduction of genes that convey traits related to environmental stresses and
Gekata [30.6K]

The options of the given question are:

method for DNA delivery

gene construct

efficient selection strategy

tissue culture system

Answer: Tissue culture system.

Explanation:

The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.

But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.

The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.
