Answer: Telophase
Explanation:
Mitosis is a process of division of the nucleus, which consists of the equal sharing of genetic material (DNA). This type of division occurs in somatic cells and the next step after mitosis is the division of the cytoplasm (cytokinesis), to form two genetically identical daughter cells.
First, it is necessary for the genetic material to be duplicated, so that each newly created cell receives the correct number of chromosomes (structure smade up of DNA). To separate these chromosomes, during <u>anaphase</u>, the chromosomes are anchored to the spindle microtubules and aligned at the metaphase plate (the center of the cell). The sister chromatids (two copies of a chromosome) are separated by the microtubules anchored to their kinetochores as they disassemble, heading toward the respective centrosomes (an organelle in which microtubules grow). Then, the microtubules pushing the centrosomes (and the set of chromosomes associated with them) toward opposite ends of the cell. Since it is necessary for the chromosomes to go to the poles of the cell, new cells are formed. So in this step, <u>it is necessary that the nuclear envelope is not present (otherwise, the nucleus could not divide).</u>
During <u>telophase</u>, microtubules not attached to kinetochores continue to elongate, further stretching the cell. The sister chromosomes are each associated with one of the poles, and as <u>the division of the nucleus is completed, the nuclear envelope reforms around both chromosome sets</u>,<u> using fragments of the nuclear envelope of the original cell.</u> The chromosomes are decondensed back into chromatin and only the cytokineses remain.
The fluorophore labels proteins that are part of the nuclear membrane and as telophase forms back, these proteins are expressed more. So, since the proteins of the nuclear envolope are labeled with a green fluoroforum, the green fluorescence would be most intense during telophase. Therefore there will be more intensity of green color compared to anaphase where the nuclear membrane is disintegrated.
Answer:
Transcribing DNA into mRNA
Explanation:
The geneome of most DNA-containing viruses that infect eukaryotic cells is transported in the cell nucleus, where the cellular DNA is, of course, also found. Once inside the cell, the viral DNA interacts.
(Hope this helps!!)
Vestigial organs are organs that we don't use but maybe our ancestor use this organ and the organ will evolve into smaller. Example : Appendix, Hair in chest, canine.
This theory come from J.B Lamarck
The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Answer/Explanation:
DNA replication doubles each chromosome, meaning the cell can pass on DNA to daughter cells - the duplicated DNA is divided equally between the two new cells formed from the parent.
The laws of inheritance are:
1) The Law of Dominance: An organism with alternate forms of a gene, called alleles, will always display the form that is dominant, masking the recessive trait.
2) The Law of Segregation: In a diploid genome, like most eukaryotes, each trait is defined by a pair of genes (alleles). Each allele is randomly passed on to the gametes so that each gamete only contains one allele. The offspring inherits one allele from each parent during the process of fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted independently from one another That is, the inheritance of one trait does not depend on the inheritance of another trait. so that the inheritance of one trait is not dependent on the inheritance of another.
