Answer:
Lipases and Amylases:
Lipases are a class of digestive enzyme produced by the pancreas. These enzymes are responsible for breaking down fatty acid chains into their smaller sub units so that they can be absorbed by the body. Amylases are a class of digestive enzyme produces by the salivary glands in the mouth and the pancreas. These enzymes breakdown carbohydrates into smaller sub units so they can be absorbed.
Explanation:
because of excessive amount of protease this problem may have protein lack causing various problem in body
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>.
It's when you use something so much that it loses it's value or purpose. But it can also mean making a piece of land more profitable and productive.
The correct answer is option B
Sperm cells when pollinated by the insect to the female body part stay there for a while til the part of the flower determines its suitability and once it is done the sperm travels down through the pollen tube.
Probiotics also known as good bacteria are beneficial to one's health. The answer to the question is all of the choices are correct. They also prevent the harmful bacteria to grow, helps in having low cholesterol and regulate metabolism as well.
