What basic unit of heredity is found on segments of DNA and are passed on from parent to offspring?

Answers

Gene is basic unit of heredity is found on segments of DNA and are passed on from parent to offspring.

What are the characteristics of gene ?

A gene is  physical and functional unit of heredity which is made up of DNA.

Genes control both DNA and RNA function.

Some genes codes protein for functional expression of a trait where as some genes do not code for proteins.

In humans, the size of genes ranges from few hundred DNA bases to more than 2 million bases and human have between 20,000 and 25,000 genes.

Each gene have two copies, one is passed from each parent. Only 1 percent of the total genes is slightly different between people.

This is because of presence two different types of allele the same gene which contribute to each person’s unique physical features.

Which of the following statements best describes the major difference between anaphase of mitosis and anaphase I of meiosis? In anaphase I, homologous pairs are separated but sister chromatids stay joined together. In anaphase, spindle fibers pull each set of sister chromatids to opposite ends of the cell. In anaphase I, sister chromatids are separated, forming a total of four haploid cells. In anaphase, tetrads of homologous pairs are separated to form four new nuclei

Answers

In anaphase I, sister chromatids are separated, forming a total of four haploid cells.


Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.

Answer:

In anaphase I, homologous pairs are separated but sister chromatids stay joined together.

Some chemotherapy drugs act by attaching themselves to the growing strand of a DNA molecule, thus preventing its replication. Cells on which phase of the cell cycle would be affected by this drug?

Answers

The answer is S phase.

If drugs prevent DNA replication which occurs in the S phase. That means that the S phase will be affected by these drugs.
is when the cell is on the S phase.

S-Phase is the part of cell cycle when the DNA is replicating, occurring between G1 and G2 phase

If the replication is somehow prevented, the drugs is most likely affecting the S-Phase
