Day-to-day choices can help reduce the risk of heart disease. One of the major risk factors for development of heart disease is elevated LDL, which can be affected by the types and amounts of dietary fat consumed as well as other dietary factors. Read the statements below and select all of the correct statements regarding how various dietary fats affect LDL cholesterol levels. Select all that apply. a. Typically, the higher your consumption of unsaturated fats, the higher the LDL cholesterol levels in your blood. b. Trans fats are worse for heart health than saturated fats because they raise LDL cholesterol and lower HDL cholesterol. c. Increasing intake of plant foods may be one of the easiest ways to decrease LDL cholesterol. d. Typically, the higher your consumption of saturated fats, the higher the LDL cholesterol levels in your blood. e. Dietary cholesterol does not affect blood cholesterol levels.

In mice, the autosomal locus coding for the β-globin chain of hemoglobin is 1 m.u. from the albino locus. Assume for the moment that the same is true in humans. The disease sickle-cell anemia is the result of homozygosity for a particular mutation in the β-globin gene.a. A son is born to an albino man and a woman with sickle-cell anemia. What kinds of gametes will the son form, and in what proportions? (2 points)b. A daughter is born to a normal man and a woman who has both albinism and sickle-cell anemia. What kinds of gametes will the daughter form, and in what proportions? (2 points)c. If the son in part a grows up and marries the daughter in part b, what is the probability that a child of theirs will be an albino with sickle-cell anemia? (1 point)

Answers

Answer:

Explanation:

The disease sickle cell anemia is caused by homozygosity for a mutation:

  • SS or Ss genotypes: normal
  • ss: anemia

Albinism is a recessive trait:

  • AA or Aa: normal
  • aa: albinism

The genes S/s and A/a are linked and separated by 1  map unit.

Remember that 1 mu means that 1% of the gametes produced by an individual will be recombinant.

a) Albino man (Sa/Sa) X woman with sickle-cell anemia (sA/sA)

Son: Sa/sA

The gametes he can produce are:

  • Parentals: Sa and sA
  • Recombinant: SA and sa

Since the frequency of recombination is 1% (or 0.01), each recombinant gamete has a frequency of 0.005 (since there are two possible recombinant gametes).

The parental gametes will appear with a frequency of 0.99, each of them with a frequenct of 0.495.

b) Normal man (SA/SA) X woman with anemia and albinism (sa/sa)

Daughter: SA/sa

The gametes she can produce are:

  • Parentals: SA (0.495) and sa (0.495)
  • Recombinant: Sa (0.005) and sA (0.005)

c) Son (Sa/sA) X daughter (SA/sa)

In order for them to have an albino child with anemia (sa/sa), the gamete sa from each parent had to be produced and fused into the zygote. Since the production of gametes by each parent is an independent event, the probability of having sa/sa offspring can be calculated as:

Prob. sa gamete son × Prob. sa gamete daughter = 0.005 × 0.495 = 0.0025

The probability that a child of theirs will be an albino with sickle-cell anemia is 0.25%

Which of the following statements about the functional consequences of single base-pair mutations are TRUE? Select the three correct answers. A) Mutations that occur in the intron sequences cannot affect the protein coding sequence of a gene. B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence encoded by a gene. C) Nucleotide substitutions within a coding sequences always change the amino acid sequence encoded by a gene. D) Missense mutations always change the amino acid sequence encoded by a gene. E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.

Answers

Answer:

these statements are true

B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence

D) Missense mutations always change the amino acid sequence encoded by a gene

E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.

Explanation:

B) insertion or deletion of nucleotide in coding region of DNA can change the amino acid sequence encoded.

D) missense mutation means that the change in nucleotide sequence resulting in change in amino acid sequence encoded by gene.

E) A mutation may alter the promoter of a gene, thereby affecting the rate of transcription.

Final answer:

The correct statements regarding single base pair mutations are: insertions or deletions within a protein coding sequence likely change the encoded amino acid sequence; missense mutations always change the encoded amino acid sequence; nucleotide substitutions outside of the coding sequence can impact gene expression.

Explanation:

Your question focuses on single base-pair mutations and their functional consequences. After considering the provided statements, the three correct answers are: B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence encoded by a gene. D) Missense mutations always change the amino acid sequence encoded by a gene. E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.

A missense mutation is a type of mutation where a single base pair is changed, leading to the substitution of a different amino acid in the resulting protein. This change can alter the function of the protein. On the other hand, insertions or deletions of single base-pairs can often lead to a frameshift mutation, which alters the reading frame and potentially changes every subsequent amino acid in the encoded protein, often resulting in a nonfunctional protein. Lastly, nucleotide substitutions outside of the coding sequence can also affect gene expression by changing areas involved in the regulation of gene transcription.

Parasitic

Competition

Mutualism

Answers

Answer:   Comensulism

Commensalism is being displayed From the video Clownfish and Sea Anemone Partnership

Explanation:

From the video Clownfish and sea Anemone Partnership there is a significant relation that can be seen from the statement itself too and that is sign of symbolism.

The relation of symbol is used for the sea anemone. So, both Clown fish and Anemone are held to be very beneficial whenever these two fishes are kept together in presence of each other.

So, it can be said clown fish and sea anemone have a very deep relation between each other.

Hydrophobic interactions between nonpolar molecules or groups: A. result from the tendency to maximize water's contact with nonpolar molecules. B. depend on strong permanent dipoles in the nonpolar molecules. C. are the result of strong replusion between water and nonpolar regions. D. are the result of strong attractions between nonpolar regions. E. require the presence of surrounding water molecules

Answers

Answer:

C

Explanation:

Final answer:

Hydrophobic interactions are the result of strong attractions between nonpolar regions and are crucial in biological phenomenon such as protein folding and cell membrane structure. The correct option is D.

Explanation:

Hydrophobic interactions often occur between nonpolar molecules or groups. The correct statement among those provided is D: hydrophobic interactions are the result of strong attractions between nonpolar regions.

These interactions do not require the presence of surrounding water molecules, nor do they result from maximizing contact with water. Instead, nonpolar molecules or groups tend to gather together, or aggregate, to minimize their exposure to water or any other polar substances.

This is because there is a natural repulsion between polar and nonpolar substances. Thus, hydrophobic interactions are critical for the folding and stability of proteins, cell membrane structure, and many other biological phenomena. The correct option is D.
