Answer:
DNA to messenger RNA (mRNA) to protein.
Explanation:
Central Dogma is a term that refers to the two step process through which information flows from the sequence of DNA into a sequence of RNA (the process of transcription) and finally takes the form of proteins (the process of translation)
Francis Crick was the first scientist who proposed the term of "Central Dogma".
Significance of Central Dogma:
- This is the process that ensures that genetic information of all living organisms is preserved and transmitted without any alteration or changes into their offspring.
- It is a process that intricately explains the logical mechanism through which DNA stored in our chromosomes express themselves into functional forms called proteins.
- This was the process which let us know the important roles of molecules like ribosomal RNA, transfer RNA and messenger RNA in the process of protein formation.
- The process has immense importance in understanding the latest advances in RNA technology that can further help in investigation and diagnosis as well as treatment of many critical diseases.

Embryonic mass cells are in constant
division, making it much easier to find good examples of each phase of mitosis. The root and the stem are the best place to
look because they contain meristematic tissue that retains the ability to
divide throughout the life of the plant.
Answer:
The correct option is e
Explanation:
An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.
From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.
NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.
Answer:
carbohydrate chain
Explanation:
Cholesterol is more rigid than some of the other lipids in the membrane. Cholesterol keeps the fatty-acid tails of the phospholipids bilayer from sticking together, which contributes to the fluidity of the plasma membrane. The membrane would become rigid. Transport protein move needed substances or waste materials through the plasma membrane
. Carbohydrate defines the cell characteristics and help cells identify chemical signals.
