The reduction in chromosome number occurs during <u>meiosis I.</u>

Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.

Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.

Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.

What is the purpose of transcription and translation?
tresset_1 [31]
Answer: The purpose of transcription is to move the information from the DNA to the ribosomes with the help of mRNA. Then we have translation it occurs on ribosomes and its purpose is to assemble amino acids into proteins.

Explanation:
the steps of transcription:
1. unzipping the DNA
2. build the RNA molecule
3. detach the mRNA molecule
4. rewinds the DNA molecule
If u want the steps of translation tell me :)

DNA replication occurs prior to meiosis and _________.
Evgesh-ka [11]
A. Mitosis is the correct answer.

DNA replication occurs in the two major types of cell division: mitosis and meiosis.

Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.

Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).

Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.
