Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.
Answer:
Well the white allele had to be Ww.
Explanation:
So you cross them and you 50% white and 50% yellow if the white parent was Ww.
Answer:
Neutrons.
Explanation:
Two atoms which are isotopes of one another must have a different number of neutrons.
Isotopes are defined as atoms of the same element which have the same numbers of protons i.e. atomic number remains the same but has different numbers of neutrons. It is observed that they have the same chemical properties due to the same electronic configuration but physical properties differ.
It is likely a <span>carbohydrate. </span>
Answer:
The two major genera of gram positive bacteria include the Bacilli , which contain the endospore-forming genera (e.g. Bacillus and Clostridium) , and the Cocci , which contains some filamentous (e.g. Streptomyces) that produce exospores.
Explanation:
The two main genera of Gram positive bacteria include:
1) Bacilli (Bacillus) : It is a group of cylindrical or rod shaped gram positive anaerobic or aerobic (some condition) bacteria found in water and soil. Bacillus bacteria can be subdivided on their ability to form spores.
2) Cocci (Coccus) : It is a type of bacterium that have a spherical, ovoid and round shape anaerobic gram positive bacteria.
