MEIOSIS
1)name the process unique to meiosis that occurs during bivalent formation that may increase genetic diversity?
2)how are sister chromatic made and what is the structure that holds them together?
3)what do we call package of genetic information (DNA), encoding a protein, needed to regulate both the individual cell and the whole organism?
AN ANSWER TO THE FOLLOWING QUESTIONS AS SOON AS POSSIBLE WOULD BE GREAT.
Sure! I can help you with those questions. Here are the answers:
1) The process unique to meiosis that occurs during bivalent formation, which may increase genetic diversity, is called crossing over or genetic recombination. Crossing over happens during Prophase I of meiosis when homologous chromosomes pair up and exchange genetic material. This exchange of genetic material leads to the creation of new combinations of genes on the chromosomes, thereby increasing genetic diversity within the resulting gametes.
2) Sister chromatids are produced during the S phase of the cell cycle, which occurs before meiosis. In the S phase, DNA replication takes place, and each chromosome duplicates. The result is two identical copies of the chromosome called sister chromatids. These sister chromatids are held together by a protein structure called the centromere. The centromere plays a crucial role in ensuring that the sister chromatids are distributed correctly during cell division.
3) The package of genetic information (DNA), encoding a protein, needed to regulate both the individual cell and the whole organism is called a gene. A gene is a specific sequence of DNA that contains the instructions for producing a particular protein or RNA molecule. Genes play a fundamental role in determining the physical characteristics, traits, and functions of an organism. They are responsible for passing on hereditary information from one generation to the next.
