Answer:
The pyrenoid, a dense structure inside or beside chloroplasts of certain algae, consists largely of ribulose biphosphate carboxylase, one of the enzymes necessary in photosynthesis for carbon fixation and thus sugar formation. Starch, a storage form of glucose, is often found around pyrenoids.
When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.
Answer: Option C
<u>Explanation:</u>
Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.
Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil. However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.
Answer:
tRNA molecules bring a specific <u>amino acid</u> to the ribosome, according to the <u>mRNA codon</u>.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that
:
- <em>The pattern in the amino acid sequence of a protein is indicated by mRNA
</em>
- <em>tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.</em>
In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.
Explanation:
main difference between competitive and noncompetitive inhibition is that competitive inhibition is the binding of the inhibitor to the active site of the enzyme whereas noncompetitive inhibition is the binding of the inhibitor to the enzyme at a point other than the active site.
