I do believe the answer is B because since it is going through each phase, the DNA strand will continue to adjust itself as the cell moves making the strands split allowing themselves to create copies. Since DNA has to be connected with another strand that will fit, it will be able to multiply itself based on the pieces that are missing
Answer: im pretty sure your correct
Explanation:
Answer:
Option (A) and (C).
Explanation:
Gene regulatory mechanism are important for the regulation of the transcription and proper expression of genes. Different regulatory mechanisms are present in prokaryotes and eukaryotes.
The prokaryotes do not require the multiple general transcription factors where as the eukaryotes have different transcription factors like TFIID, TFIIH and TFIIA. The DNA is packed around the histone protein that form chromatin in eukaryotes. The chromatin packaging includes methylation, ribosylation with the help of enhancers and silencors. The chromatin is absent in case of prokaryotes.
Thus, the correct answer is Option (A) and (C).
A, B, AB and O
It’s the universal plasma donor
Photosynthetic cell that lacks a nucleus is to be placed in bacteria.
A prokaryotic cell is a simple, one-celled (unicellular) organism devoid of a nucleus or any other membrane-bound organelle.
Unlike Archaea and eukaryotes, bacteria have a polysaccharide capsule and a peptidoglycan cell wall formed of sugars and amino acids. The cell wall serves as an additional layer of defence, aids in maintaining the cell's form, and stops dehydration. In addition, the cell can adhere to surfaces in its environment thanks to the capsule.
Fimbriae, pili, or flagella are present in several prokaryotes. While most pili are employed to exchange genetic material during conjugation, a sort of reproduction, flagella are used for motility.
