Answer:
Sigma factors bind to the promoter region of a particular gene and facilitating the binding of RNA Polymerase to the promoter region (formation of the RNA polymerase holoenzyme complex) in order initiate transcription of the gene.
Put simply - Helps RNA Polymerase do it's job.
Answer:
The correct answer will be option- B.
Explanation:
The Transduction is the process of the genetic transfer by which the foreign DNA is incorporated in the genome of the cell using virus or bacteriophage. The process of transduction was discovered by the Zinder and Lederberg in 1952 in the species of<em> Salmonella</em> bacteria. The transduction process is of two types: generalized and specialized transduction.
Thus, option- B is the correct answer.
The correct answer is codominance.
Codominance is when the alleles of a gene, in a heterozygote organism, are not fully expressed. In this case, either red or white fully dominates but they still manifest that they are present in the flower.
Do not get confused with incomplete dominance because that would result in a pink flower.
Answer:
Zooplankton
Explanation:
The correct answer here would be the zooplankton. (see the attached image)
<em>Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem. </em>
<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
There are several ways;
The Skeletal system protects for example the heart and several aspects of large vasculature. The skeleton also has the means to produce blood cells in the marrow of some of the bones.
