I think it’s D. H2, NaCI, CO
Answer:
The correct answer will be-
3'- T U U C G C T T G U C G C T C C T G U U G -5'.
Explanation:
The formation of the mRNA from the template strand or anti-sense strand is known as the transcription.
The nucleotide in the mRNA is added in the same way as the DNA according to the Chargaff rules which states that A will bind to T and G will bind to C but instead of adenine in mRNA will add uracil.
On the basis of this, the mRNA strand will be-
template strand: 5' A T T G C G A A C T G C G A G G A C T T C- 3'
mRNA strand: 3'- T U U C G C T T G U C G C T C C T G U U G-5'.
A rock that forms when magma hardens beneath Earth's surface is called an intrusive igneous rock.
Options for part A are as follows:
A) A mutation in the operator sequence
B) A mutation in the lac-Z gene
C) A mutation in the lac-Y gene
D) A super repressor mutation
Answer:
The correct answer:
Part a - A mutation in the operator sequence
Part b - It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part C. true.
Explanation:
part a:
If there is a mutation in the operator sequence leads to prevent binding of the repressor which leads to allowing constitutive expression of the genes various conditions.
part b:
The biological role of the lac operon makes sure that the cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part c:
RNA polymerase cannot transcribe the structural genes due to the repressor binds to the lac operator, therefore, the proper function of the lac operon is possible when the placement of the operator sequence between the promotor and the structural genes.
The answer is A , I hope this is not to late
