Answer:

True

Explanation:

Acceptable Macronutrients Distribution Ranges refers to adequate amount of macronutrient that should be taken in diet to avoid chronic illness or simply AMDR refer to healthy ranges of intake for carbohydrate, fat, and protein.

ADMR tells about how the protein, Lipids and carbohydrates should be distributed in diet or how much of energy should be obtained from each macronurient.

ADMR for adults are;

Protein; 10-35%, Fat; 20-35%, Carbohydrates; 45-65%.

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.

Normal hemoglobin protein in a RBC

DNA CTG ACT CCT GAG GAG AAG TCT

Amino acids Leu Thr Pro Glu Glu Lys Ser

Sickle cell hemoglobin protein in a RBC

DNA CTG ACT CCT GTG GAG AAG TCT

Amino acids Leu Thr Pro Val 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 change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.

List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood typ

ziro4ka [17]

Answer:

The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.

The table is given below:

Blood Type Genotype

Blood Type A Genotypes AA or AO

Blood Type B Genotypes BB or BO

Blood Type AB Genotype AB

Blood Type O Genotype OO

The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.

3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.

<h3>How is lineage improvement done?</h3>

The answer is to obtain populations with genetic variability. This can be achieved through hybridization or crossbreeding. Hybridization is the fusion of genetically different gametes, which results in hybrid individuals heterozygous for one or more loci.

With this information, we can conclude that 3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.
