Answer:

The correct answer is option 3. "secondary structure".

Explanation:

The secondary structure of polypeptide and proteins refers to the second order of folding, including common structures such as beta sheets, alpha helix, as well as turns and loops. The hydrogen bonds between the oxygen and nitrogen atoms of the peptide bonds are crucial to secondary structures, as these hydrogen bonds form and stabilize the aforementioned common structures.

Explain the different preparations of cocaine and how they are used.
VLD [36.1K]
<span>Cocaine Preparations -Coca leaves --> Coca Paste (60% pure): Not water soluble, so you can't inject it into the bloodstream -- you need an additional chemical step to turn the paste into crystal powder that can be injected or snorted -Coca --> Cocaine Hydrochloride (99% pure): Doesn't hold up very well to heat, so you can't smoke cocaine hydrochloride -Cocaine Hydrochloride (99% pure) --> Free-Base Cocaine or Crack Cocaine: -Reconvert cocaine hydrochloride back to base state by removing hydrochloride from cocaine (that's why it's called free-base cocaine) -Crack cocaine is a crystallized form, mixture of cocaine and baking soda -75% pure -Can be used at lower doses and is much cheaper than cocaine -Can be smoked</span>

Arrange the events taking place during transcription in order: i) The pre-RNA undergoes processing ii) RNA polymerase moves down
Anastasy [175]

Answer:

RNA polymerase binds to the promoter

Polymerase initiates RNA synthesis at the start point on the template strand

RNA polymerase moves downstream unwinding the DNA

RNA transcript is released and polymerase detaches from the DNA

The pre-RNA undergoes processing

Explanation:

The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.

The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.

In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.
