The genes are the sentences.
Gene = a segment of DNA that codes for a particular trait
The industrial revolution damaged our ecosystem
Answer:
The correct answer is - 1.57 × 10⁶ codons.
Explanation:
Given:
No. of base pairs in E.coli DNA = 4.70 × 10⁶
we know :
1 codon = 3 DNA nucleotides
Solution:
No. of of base pairs in DNA = No. of nucleotides in a single strand
= 4.70 × 10⁶
It must have 1/3 this number of triplet codons
= 4.70 × 10⁶ / 3
= 1.57 × 10⁶ codons.
Thus, the correct answer is - 1.57 × 10⁶ codons.
Answer:
Hello. I numbered your cells to make it easier to name them. The image with the numbers is attached.
cell 1: Interphase.
Cell 2: Telophase.
Cell 3: Metaphase.
Cell 4: Prophase
Cell 5: Interphase.
Cell 6: Anaphase.
Explanation:
In the interphase, it is possible to notice that the cell increased its volume, due to the increase in the size of the organelles and the increase in the number of the organelles, which indicates the beginning of the cell cycle.
Prophase is really the beginning of the cell cycle. At that moment, you can see that the nuclear membrane has been disorganized and we can see a 'tangle' of the cell interior that is very full and disorganized. This is mainly because the material present in the nucleol spreads through the cell.
In the metaphase, the chromosomes are condensed and start to connect to each other forming the spindle fibers, which are located right in the middle of the cell, forming the equatorial plate.
In anaphase there is a rupture of the centromeres and sister chromatids. Each part of these elements migrates to one of the poles of the cell. This is mainly due to the shortening of the spindle fibers.
Telophase is the final phase of the cell cycle, at that moment, the spindle fibers disappear, the chromosomes are condensed and the nuclear membrane is reconstructed. However, the cell has not yet separated and it is possible to see two nuclei in a single cell, each nucleus is at a pole, indicating that the division will occur.
