Answer:

a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

At the end of meiosis i, there are two haploid cells, each with two sister chromatids per chromosome. True or false?.
jok3333 [9.3K]

True.

At the end of meiosis I, there are two haploid cells.

<h3>What is the process of meiosis I?</h3>

Meiosis I refers to the initial nuclear division that takes place when gametes are formed. Due to the fact that the resulting cells have half as many chromosomes as the parent cell, it is also referred to as the reduction division. Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.

Prophase I:

The chromosomes condense during prophase I and become apparent inside the nucleus. Following this chromosomal condensation, each chromosome pair's members align adjacent to one another and are referred to as homologous chromosomes because of their identical size and gene content.

At this stage, a mechanism known as synaptic attachment occurs between the two chromosomes in each pair along their lengths. Then, while the homologous chromosomes are tightly coupled, the individuals within each pair cross over, also known as recombination, to exchange neighboring pieces of DNA. The nuclear membrane eventually starts to deteriorate after the conclusion of prophase I.

Metaphase I:

Microtubules leave the spindle at the beginning of metaphase I and join the kinetochore close to the centromere of each chromosome. In specifically, microtubules from one spindle side bind to one chromosome while those from the other spindle side adhere to the other chromosome in each homologous pair. The chromosomal pairs subsequently align themselves along the equator of the cell, forming the metaphase plate, with the assistance of these microtubules.

Anaphase I:

The homologous chromosomes are separated during anaphase I by the disintegration and contraction of the microtubules, which causes the two chromosomes in each pair to be drawn toward the opposite ends of the cell. Because of this division, each daughter cell that emerges from meiosis I will have half as many chromosomes following interphase as the original parent cell. Additionally, each chromosome's sister chromatid still has a connection.

Telophase I:

In telophase I, the cytoplasm organizes and separates into two as the new chromosomes approach the spindle. Now there are two cells, and each one has half as many chromosomes as its parent cell did. The recombination that took place during prophase I also caused the two daughter cells to not be genetically identical to one another.

An example of natural immunity is  a fetus acquiring maternal igg to the chickenpox virus across the placenta. Option D

<h3>What is natural immunity?</h3>

The term natural immunity refers to the ability of the body to defend itself from invaders which are pathogenic. There are two kinds of natural immunity which are;

  • Active immunity
  • Passive immunity

Since natural immunity could be due to a person's immune system or may be gotten from another person, it follows that an example of natural immunity is  a fetus acquiring maternal igg to the chickenpox virus across the placenta. Option D
