Answer:
C- Dominant, but not sex-linked
Explanation:
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
Answer:
O and Q
Explanation:
Why O: Because gas has a lot of energy and movement and doesn't have a definite shape or volume, it can move as much as it likes, but when it condenses, it becomes a liquid, and a liquid has a definite volume, but no definite shape, and has less energy and movement.
Why Q: Because liquid has a definite volume, but no definite shape, and a good amount of energy and movement, but when it freezes it loses its energy and movement, and becomes a solid, and a solid has a definite volume and shape and the particles can barely move enough to vibrate
I hope you at least understand my concept. :)
fats are composed of high amounts of saturated fatty acids which are solid at room temperature and oils are composed of mainly unsaturated fatty acids which are a liquid at room temperature
Answer:
1. The difference between the normal hemoglobin protein DNA sequence and the sickle cell hemoglobin DNA sequence is a base to base shift, in this case adenine (GAG) to thymine (GTG).
2. The difference affects the amino acid sequence of the protein by replacing glutamic acid (Glu) with valine (Val).
Explanation:
In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the amino acid sequence of globine β, incorporating valine instead of glutamic acid. This represents a molecular mutation - point mutation - by subtitution, which corresponds to missense mutation.
<u>Normal hemoglobin protein in a RBC</u>
DNA CTG ACT CCT GAG GAG AAG TCT
Amino acids Leu Thr Pro Glu Glu Lys Ser
<u>Sickle cell hemoglobin protein in a RBC</u>
DNA CTG ACT CCT <em>GTG</em> GAG AAG TCT
Amino acids Leu Thr Pro <em>Val</em> Glu Lys Ser
When GAG is transcribed to mRNA, the CUC codon is obtained, which codes for glutamic acid. Thymine substitution causes the DNA sequence to change to GTG, which is transcribed as CAC, the codon that encodes the amino acid valine. The <u>change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease</u>.
