The DNA changes that are described in Henry’s story are changes to the coding strands of the CYP2C9 genes. What is the function of the coding strand and how does it differ from the function of the template strand of Henry’s CYP2C9 gene? The function of a coding strand is the strand that is going to be transcribed. The function of a template strand is the complementary strand from the coding strand. The template strand is what is used as a template in the synthesis of
Interpahse includes the G1, S, and G2 phases of the cell cycle. Cells in interpase grow and undergo the various metabolic processes needed for their functioning during G1, S, and G2. Mitosis has 4 major stages -Prophase, Metaphase, Anaphase, and Telophase. During interphase, DNA replication occurs. After duplication the cell is ready to begin mitosis.
The production of amino acid is coded by a sequence of how many bases on the DNA molecule? a. Two b. Three c. Four d. Five e. Six 5. Portions of the DNA molecule useful for DNA typing: a.
What is genetic engineering Genetic engineering: The manipulation of an organism’s genes. Genetic engineering is a method of combining techniques of genetics and biotechnology used to separate and join genetic material, DNA, from one or multiple species of organism and to introduce the result into an organism to change one or more of its characteristics. Recombinant DNA technology: The technology used in which a series of procedures are used to recombine DNA segments. A recombinant DNA molecule is produced from segments of two or more different organism’s DNA. Under the correct conditions, a recombinant DNA molecule can move into and replicate in a cell, either by means of integration into a chromosome or by its self.
Take the quiz. 1. Description of Meiosis Meiosis is the type of cell division used to produce gametes (sperm and eggs). Meiosis assures that genetic diversity is achieved during sexual reproduction. Meiosis consists of 2 cell divisions: Meiosis I and Meiosis II.
Kinetochores are the protein area of the centromere on each sister chromatid. The centromere is the area where both the sister chromatids contact one another. There are two kinetochores for each chromosome. -the cell has a circular shape Metaphase -mitotic spindle has moved chromosomes to the middle of the cell -**chromosomes are
RNA primase lays the beginning for DNA Primase to begin laying down the nucleobases: Adenine, Thymine, Cytosine and Guanine. 3. Okazaki fragment from RNA primase a segment of the lagging strand during replication. 4. DNA ligase goes over all the small Okazaki segments and binds them into a new strand of DNA.
F. The plasma membrane controls the movement of substances in and out of the cell. G. The role of the Smooth Endoplasmic Reticulum is to detoxify the organ or cell. H. Chromatin (DNA) is formed when hereditary material and protein combine. They then condense and from chromosomes for cell division. I.
4 – Dismantles debris B. 6 – Protein synthesis C. 2 – Houses DNA D. 1 – Lipid synthesis E. 7 – Processes secretions F. 3 – Energy extraction G. 5 – Detoxification 2) Explain the functions of the following proteins: A. Tubulin and Actin – Tubulin forms microtubules, while actin forms microfilaments. B. Caspases – Caspases are responsible for apoptosis. C. Cyclins and kinases – The interaction of cyclins and kinases trigger mitosis from the inside. D. Checkpoint proteins – Checkpoint proteins are responsible for regulating the cell cycle.
Proteins are formed through condensation reactions which bond amino acids together with peptide bonds in a particular sequence and the type of protein that is created is defined by the unique sequence of the amino acids. DNA and RNA are nucleic acids that are formed in the nucleotides and are both involved in the process of protein synthesis. Deoxyribonucleic acid, more commonly known as DNA, is located within the nucleus of the cell and contains the entire genetic code for an organism within its structure. DNA has two very important functions which are: to convey information from one generation of cells to the next by the process of DNA replication and to provide the information for the synthesis of proteins necessary for cellular function. Basically, DNA controls protein synthesis.
