1. How many different phenotypes are possible in the offspring of two parents with genotypes AA and aa, where A is the dominant

allele for a trait and a is the recessive allele for the same trait? one
two
three
four
2. A woman buys red-flowering and blue-flowering plants of the same species and plants them in her garden. The plant undergoes both self-fertilization and cross-fertilization. The woman collects seeds and plants them the following spring. What can the woman expect to observe in the flowers of the new generation of plants if the gene for flower color is codominant? (1 point)
plants with red flowers and plants with blue flowers
plants with both red and blue flowers
plants with red flowers, plants with blue flowers, and plants with purple flowers
plants with purple flowers
3. What is formed at the end of meiosis?
two genetically identical cells
four genetically different cells
four genetically identical cells
two genetically different cells
4. Which of the following is true concerning DNA replication?
The original DNA molecule remains intact, although it acts as a template for the formation of a copy that contains two new antiparallel strands.
The leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5’ direction.
Both strands are copied to form Okazaki fragments, which are later annealed by DNA ligase.
The replication process proceeds on both strands in the same direction, which requires that RNA primers bind to the lagging strand.
5. Which of the following will be directly affected in a bacterial cell that has a mutation in its gene for RNA polymerase?
Which of the following will be directly affected in a bacterial cell that has a mutation in its gene for RNA polymerase?
transcription
translation
gene regulation

For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.

Summarize the process of fertilization and implantation.
Aneli [31]
The process of fertilization involves the deposition of sperms into the vagina to the egg cell during sexual intercourse. Sperms make their way towards the cervix and uterus, and eventually goes to the fallopian tubes. <span>Only a few hundred will remain as they interact with the egg through the use of their heads and movement patterns.

</span><span>The process of implantation happens when the embryo, the fertimized eggs develops inside the fallopian tube after three days, and then travels to the uterus.</span>

During which stage of the cell cycle does the cell rest, grow, and copy DNA and organelles?
atroni [7]

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication.
