The following figure represents a strand of DNA being replicated in E.
Question The following figure represents a strand of DNA being replicated in E. coli. The top strand represents the newly synthesized strand, and the darker shaded bases in the top strand represent primer nucleotides. Use the figure to answer this question and the previous question (the figure will be shown again with each question).1) TRUE OR FALSE If you were told that the site of initiation for replicating this molecule is not within the figure shown, you could predict that the site of initiation lies closer to the nucleotide labeled (A) than to the nucleotide labeled (F).2)The nucleotide, incorporated into the newly synthesized strand by DNA polymerase III, which has been in place the longest period of time is labeled: (C) (A) (E) (B) (D)
1.Which one of the following describes the FUNCTION of mRNA during Bacterial protein synthesis?
Question 1.Which one of the following describes the FUNCTION of mRNA during Bacterial protein synthesis? mRNA is made complementary to a gene in the DNA.A 40S and a 60S ribosomal subunit will attach to the mRNA to begin translation.mRNA consists of a series of anticodons that determine the amino acid sequence of a polypeptide or protein.2.Which one of the following describes the FUNCTION of tRNA during bacterial protein synthesis?Each of the tRNA molecules picks up and carries a specific protein to the ribosome.tRNA is involved in the transcription stage of protein synthesis.Each tRNA molecule has a specific anticodon that will pair with a specific complementary codon along the mRNA.3.Which one of the following describes the FUNCTION of a codon during bacterial protein synthesis?A codon on a molecule of tRNA hydrogen bonds with an anticodon along a molecule of mRNA to insert the correct amino acid in the correct place during translation.With the exception of the 3 stop codons, a codon codes for a particular amino acid in a protein. Codons are copied into complementary genes by the enzyme RNA polymerase.

Develop a good critical-thinking answer for two of the case study
Question Get Answer Develop a good critical-thinking answer for two of the case study questions listed below, your response based on scientifically -Using scientific information to back up your statements, answer two of the questions listed below to help shape your initial post -Using scientific information to back up your statement(s).Case History Information ~ What if I told you that Jason has Acute Lymphocytic Leukemia (ALL is a type of blood cancer)? Use at least two of the following questions to help you develop a discussion with your “fellow health care worker regarding Jason’s diagnosis. Question list for Module One Discussion. Answer two of the following questions to help you develop your main discussion post. Remember that all your response must be based on scientific information.1) Select one of the organs, organ systems or tissues found in the human body and discuss how Jason’s conditions would or would not affect its normal range of functions. -Your answer must contain scientific information about the normal function(s) of the tissue, organ or organ system you have selected and how Jason’s condition would, or may impact it.2) What long term, potentially permanent changes would you predict could be observed in specific tissues, organs or organ systems as a result of Jason’s condition?3) What homeostatic evidence was present on the medical form that indicated the presence of his condition? -Don’t just list the results of his exam and blood tests, also discuss what they specifically reveal about the normal range of functions of specific tissues, organs or organ systems.Remember that indirect measurements can give health care practitioners insight into the health of the various body systems. The indirect measurements recorded on the medical forms provide “clues” about Jason’s condition.Background information you should use to identify and interpret Jason’s test results that fell outside the acceptable ranges for each test value. -Fasting glucose above normal range indicate diabetes. -Sodium levels increase when there is excess water loss due to vomiting, excessive sweating (to name a few). Decreased sodium levels may be due to impaired adrenal gland function. -High potassium levels indicate renal failure or decreased adrenal activity. Low levels indicate diuresis (e.g due to diabetes or use of diuretics). -Low protein and albumin levels indicate poor nutritional status. -GGT (gamma-glutamyl transaminase) and lactate dehydrogenase are liver enzymes. GGT levels tend to be elevated with alcohol or drug abuse or chronic hepatitis (liver inflammation). -Lactate dehydrogenase isoenzymes increase under conditions such as heart attack, sickle cell crisis, or early hepatitis. -BUN (blood urea nitrogen) and creatinine are both indicators of kidney function; elevation of both indicates impaired renal (kidney) function, while elevation of just BUN is typical of dehydration. -Globulin levels provide information about immune system functioning. -High cholesterol and triglyceride levels are related to the development of arteriosclerosis. -Low iron levels indicate anemia, especially in combination with low RBC (red blood cell) counts and low hemoglobin and hematocrit results. The hematocrit is the percentage of cells in the blood. -A high WBC (white blood cell) count may indicate infection or leukemia, while low WBC levels may be caused by radiation or certain drugs. Patients with a low platelet count tend to bleed from capillaries and small venules, creating small, purplish blotches on their skin. -TSH is thyroid-stimulating hormone; low levels result in slow metabolism and sluggishness. High levels can cause nervousness, heart palpitations, and weight loss. -The items left blank on the medical form were considered unnecessary by the doctor based on the patient’s symptoms. In the absence of specific symptoms, it is unnecessarily costly to perform certain tests.
