Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.
There would be 23% because adenine pairs with uracil and it would be even.
That means that the person you are talking about is 39% native american
Answer: Option C
Explanation:
Protein building begins on the DNA strand. Usually, the DNA contains genetic information which flows from nucleic acids to proteins in a series of steps:
1) Replication: this is the first step. It involves the copying of parental DNA into daughter copies.
2) Transcription: this is the second step. Here, parts of the coded genetic message in DNA are copied precisely in the form of RNA - in the form of messenger RNA (mRNA).
3) Translation: this is the third step. Here, genetic message coded in mRNA is translated, on the ribosomes, into a protein with a specific sequence of amino acids.
Simply put, DNA makes RNA, and RNA makes protein.
