The ( nitrogenous bases) of dna form the rungs linking the ( base) strands together through ( a base pair)
Answer:
Breaking carbohydrates into their subunits will yield Monosaccharides .. as products. Breaking down proteins will yield Amino acids .... as products.
Answer:
Transcription is affected via the modulation of the concentrations of the different types of holoenzymes, so saturated promoters are only weakly affected by sigma factor competition. However, in case of overlapping promoters or promoters recognized by two types of sigma factors, we find that even saturated promoters are strongly affected. Active transcription effectively lowers the affinity between the sigma factor driving it and the core RNAP, resulting in complex cross-talk effects. Sigma factor competition is not strongly affected by non-specific binding of core RNAPs, sigma factors and holoenzymes to DNA. Finally, we analyze the role of increased core RNAP availability upon the shut-down of ribosomal RNA transcription during the stringent response. We find that passive up-regulation of alternative sigma-dependent transcription is not only possible, but also displays hypersensitivity based on the sigma factor competition.
We are asked to determined which of the following choices above will be the correct shared property of a lipid and carbohydrate. To know the answer we must evaluate each of the choices.
a. Both have the same number of oxygen atoms
- This is incorrect. Oxygen atoms of carbohydrate and lipids are different since
lipid are usually unsaturated.
b. Both are sources of cellular energy.
- Carbohydrates is the main energy source of human body while lipids are the standby energy source when all the carbohydrates are consumed in the body.
c.Both are dissolvable in water.
-This is incorrect. Lipids are non-polar while water is polar. Like dissolves Like.
d. Both have the same proportion of carbon-hydrogen atoms
-This is incorrect since Lipids are usually double bonded atoms. thus it contain lesser amount of carbon compared to carbohydrate.
Therefore, the correct answer to this is letter B. Both are sources of cellular energy.

</span><span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. </span>
