During follicular phase which hormones have highly secreted in mentrual cycle
Answer: The follicular phase of the menstrual cycle is defined as the first day of menstruation until ovulation. It is initiated by a rise in follicle-stimulating hormone (FSH) levels at the first day of the cycle. This is triggered by a decrease in progesterone and estrogen (which act to inhibit FSH secretion).

Why does a cell need to copy its DNA before undergoing mitosis?
what is required for the initiation of an enzyme
Answer:
RNA poly merase
Explanation:Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

Indicate whether each of the following occurs mainly in G1 phase (G), S phase (S), or G2 phase (H) of the cell cycle. Your answer would be a four-letter string composed of letters G, S, and H only, e.g. HGSS. ( ) DNA helicase activation ( ) DNA helicase deposition on DNA at the replication origins ( ) ORC phosphorylation ( ) Licensing of replication origins
Answer:
the answer is S-G-S-G
Explanation:
DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.

when a cell goes through mitosis and cell division, the two new cells have _?
Answer:
D. Same number of chromosomes as the original cell
Explanation:
Mitosis is a kind of cell division which results in two daughter cells that are genetically identical to one another and the parent cell. Mitotic division causes each daughter cell to contain the SAME NUMBER OF CHROMOSOMES as the parent cell.
For example, a somatic human cell contains 23 pairs of chromosomes. If this cell undergoes division by mitosis, the two daughter cells that will result will contain 23 pairs of chromosomes each. This means that the two new cells that results from mitosis have the same number of chromosomes as the original cell.
In order for high force crossbridges to form in contracting skeletal muscle, calcium must a. bind to calmodulin to phosphorylate the myosin. b. phosphorylate the tropomyosin which moves it. c. phosphorylate the troponin to move the tropomyosin. d. bind to tropomyosin which moves the troponin. e. bind to troponin which moves the tropomyosin.
Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

Which of the following best explains how the prokaryotic expression of a metabolic protein can be regulated when the protein is already
present at a high concentration?
Answer:
A. Repressor proteins can be activated and bind to regulatory sequences to block transcription.
Explanation:
its A
The best explanation for the prokaryotic expression of a metabolic protein is repressor proteins can be activated and bind to regulatory sequences to block transcription.
What are metabolic proteins?Protein helps with growth and repair. Proteins have the potential to serve as a metabolic fuel source in addition to all of these important functions.
Excess proteins must be converted into glucose or triglycerides and used to provide energy or build energy reserves because proteins cannot be stored.
Thus, the correct option is A.
