15 years for scientist to classify an area's weather as its climate.
Answer: The correct answer is option C. To form RNA molecules from DNA molecule.
Explanation:
The main function of transcription is to form ribonucleic acid (RNA) molecules from deoxyribonucleic acid (DNA) molecule present in the nucleus. In transcription, small part of DNA is copied and attached to the RNA molecule with the help of enzymes i. e. RNA polymerase.
DNA replication occurs in the 5 prime (5') to 3 prime (3') direction.
I'm sure you've heard this many times. I tutor in genetics, and all of my students can rattle that off. Less understand what it means.
First, understanding what 5' and 3' mean is important. DNA is composed of a ribose sugar, a phosphate group, and a base (A,T,G,C). The sugar has a phosphate group attached to its fifth carbon, and a hydroxyl group on its 3rd carbon. Nucleotides (separate components of DNA) are linked by the phosphate group and the hydroxyl group. So, every nucleotide is linked at the phosphate group and the hydroxyl group besides two - the two nucleotides at either end of the strand of DNA. The one that leaves a phosphate group exposed is called the 5' end of DNA, and the one that leaves a hydroxyl group exposed is called the 3' end of DNA.
<span>A problem with many students just memorizing that replication occurs in the 5' to 3' direction is that there are two strands of DNA involved in replication. DNA polymerase (the major enzyme responsible for replication) reads the already existing strand of DNA in the 3' to 5' direction, and creates the new strand of DNA in the 5' to 3' direction (meaning that it adds nucleotides to the 3' end of the new strand).</span>
To prevent cells from either shrinking or swelling you should keep them in an isotonic solution. Isotonic solution is a solution with equal amount of solute and solvent. Therefore, when cells are placed in such a solution they will not lose or gain water, as opposed to hypertonic (more solute than solvent) and hypotonic (more solvent than solute) solutions.
