Answer:
Nitrogenous base
Explanation:
Phosphate and deoxyribose create the "backbone" of a DNA molecule.
Think of the molecule as a ladder.
These(deoxyribose and phosphate) are the sides of the latter.
The nitrogenous bases(A,G,C,T) are the rungs of the ladder.
As the arrow points to the "rung" of the ladder, that means it is a nitrogenous base.
Answer:
No. Gender traits in humans are largely determined by biophysical processes.
If i'm wrong, i'm rlly rlly sorry!!
Answer:
Proteins.
Explanation:
Use these mnemonics:
Carbohydrates & Lipids - CHO
Proteins - CHON
Nucleic acids - CHONP
We can immediately eliminate carbohydrates and lipids, as we can see an "N". There is not a "P" visible either, meaning we can rule out nucleic acids. We are left with proteins.
Answer:
Rho protein.
Explanation:
Transcription may be defined as the process of formation of RNA molecule from the DNA template. Three important process of transcription are initiation, elongation and termination.
The termination may occur through rho dependent and rho independent mechanism. In rho independent termination, the rho proteins are not required and not necessary for the termination. The uracil stretch is important for rho independent termination.
Thus, the correct answer is option (b).
Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.
Explanation:
Binary fission and mitosis can be viewed as the same principle of asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.
Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.
