What are the phases of meiosis? ( full explanation and in order )
Alexandra [31]
Interphase: -the cell replicates its chromosomes -each chromosome has two sister chromatids held together by a centromere Prophase 1 chromosomes coil up and a spindle forms -homologous chromosomes come together matched gene by gene forming a tetrad -Crossing Over may occur when chromatids exchange genetic material -this occurs two or three times per pair of homologous chromosomes -Crossing Over results in new combinations of alleles on a chromosomes Metaphase 1: -the centromere of each chromosome becomes attached to a spindle fiber -the spindle fibers pull the tetrads to the equator of the spindle -homologous chromosomes are lined up side by side as tetrads Anaphase 1: -homologous chromosomes separate and move to opposite ends of the cell -centromeres do not split -this ensures that each new cell will receive only one chromosome from each homologous pair Telophase 1: -the spindle breaks down and the chromosomes uncoil -the cytoplasm divides to yield two new cells -each cell has half the genetic information of the original cell because it has only one homologous chromosome from each pair Prophase II- -a spindle forms in each of the two new cells and the fibers attach to the chromosomes Metaphase II- -the chromosomes are pulled to the center of the cell and line up randomly at the equator Anaphase II- -the centromere of each chromosome splits the sister chromatids separate and move to opposite poles Telophase II nuclei re form  the spindles break down  the cytoplasm divides identical to mitosis (Meiosis II) What Meiosis produces four haploid sex cells from one original diploid cell each haploid cell contains one chromosome from each homologous pair haploid cells will become gametes transmitting genes to offspring

Which proccess in respiration happens first
Ad libitum [116K]

Answer:

glycolysis that is the first step in cellular respiration

Explanation:

According to research :

Glycolysis is the metabolic pathway that converts glucose C₆H₁₂O₆, into pyruvate, CH₃COCOO⁻, and a hydrogen ion, H⁺. The free energy released in this process is used to form the high-energy molecules ATP and NADH. Glycolysis is a sequence of ten enzyme-catalyzed reactions. Wikipedia

Hydrophilic means ____ love of water fear of water a water pressure mechanical system related to dams
kow [346]

Answer:

love of water

Explanation:

HYDROPHILIC is a term used for substances that are WATER-LOVING in nature. As the name implies, hydro-meaning water and philia- meaning love, it means the love of water. Substances that are hydrophilic tend to be attracted towards water molecules and are readily dissolved by it. For example, sugar molecules are hydrophilic, hence, attract and dissolve in water.

On the other hand, hydrophobic means water-fearing i.e substances under this category repel water. Examples are some fat molecules.

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an
Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
