Lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
<em>Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.</em>
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.
Answer:
Mutation occurred in ribosome binding site that serves as binding site for 30S ribosomal subunit of <em>E. coli</em> and allows the process of protein synthesis to begin.
Explanation:
The initiation of protein synthesis in bacteria requires binding of the ribosome to the ribosome binding site. The ribosome binding site in bacteria consists of the initiation codon "AUG" and the preceding Shine-Dalgarno sequence. The AUG initiation codon and Shine Delgrano sequence are around 10 bases apart.
The sequence is polypurine hexamer and is represented by 5' ...AGGAGG...3'. Shine-Delgrano sequence is complementary to the conserved sequence present at the 3' end of 16SrRNA of the 30S subunit of the bacterial ribosome. Binding of Shine Delgrano sequence of ribosome binding site and the complementary sequence of the 30S ribosomal subunit marks the first step in the initiation of protein synthesis.
Any mutation in the ribosome binding site would not allow the process of protein synthesis to start or would reduce the rate of the initiation of protein synthesis.
In my opinion, the correct answer among the choices listed is option C. The members of the kingdom Protista are least similar to a bacteria. Protists are eukaryotic organisms which cannot be classified as a fungus, animal, or a plant. They are mostly unicellular organisms.
