Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
Answer:
The correct answer is option D) six dominant and two recessive.
Explanation:
The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).
Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.
Thus, the correct answer is option D) six dominant and two recessive.
Brain, Brain stem, Idk, Temporal Lobe....I think this is fairly for the most part correct
