To review:
The diet group having highest LDL (low-density lipoprotein) to HDL (high-density lipoprotein) ratio. The results of the study are shown in the table given below:
Effect of Diet on Lipoprotein levels (mg/dL or milligram per deciliter) | ||||
cis Fatty acids | Trans Fatty acids | Saturated Fats | Optimal level | |
LDL | 103 | 117 | 121 | <100 |
HDL | 55 | 48 | 55 | >40 |
LDL-to-HDL ratio | 1.87 | 2.43 | 2.2 | <2 |
Introduction:
Lipoproteins are made up of proteins and lipids. These molecules help in the transportation of lipids (mainly cholesterol) in the blood or extracellular fluid. The phospholipids are present on the exterior while other lipids lie in the interior. Phospholipids are oriented in such a way that the hydrophilic part is on the outer side while the hydrophobic part is on the inner side.
On basis of density, lipoproteins are classified as Ultra Low-Density Lipoproteins (ULDL), Intermediate Density Lipoproteins (IDL), Very Low-Density Lipoproteins (VLDL), LDL, and HDL. The LDL and HDL are of clinical importance and are classified as bad cholesterol and good cholesterol, respectively.

Enter the number of milligrams of zinc rounded to the first decimal place in the box below. ______ mg ?arrow_forwardthe direct output from molecular replacement is a coordinate file showing the orientation of the unknown target protein in the unit cell. true or false?arrow_forwardthe direct output from molecular replacement is a coordinate file showing the orientation of the unknown target protein in the unit cell. true or false?arrow_forward
- Did your intake of vitamin C meet or come very close to the recommended amount? yes noarrow_forwardWhich of the following statements about hydration is true? Absence of thirst is a reliable indication that an individual is adequately hydrated. All of these statements are true. Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration. Urine that is the color of apple juice indicates dehydration. I don't know yetarrow_forwardThree of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.

The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle?
