Answer: The type of inheritance shown by the gene that control sickle cell anaemia is autosomal recessive inheritance
Explanation: Autosomal recessive inheritance means that there is mutation in two copies of the gene in a cell. Sickle cell anaemia is a condition caused by a single point mutation in the two beta chains of haemoglobin. Haemoglobin is a protein in the red blood cells responsible for oxygen transport to the cells. The mutation is caused by substitution of valine in place of glutamate at the sixth position of the two beta chains of haemoglobin.
Every individual has two copies of almost every gene, one from the mother, and one from the father. The autosomal recessive inheritance pattern of sickle cell gene means that for an individual to manifest outwardly as sickle cell, the two copies of the gene inherited from the parents are mutated.
More because if the condition changed it would not be the same like it was before it was changed.
Answer:
c. amino acids
Explanation:
Amino acids are the monomers of proteins. Two amino acids combine in a condensation reaction that releases water forming a peptide bond. These two amino acid residues form a dipeptide. If a third amino acid is bound, a tripeptide is formed and so on to form a polypeptide.
The amino acids are formed by an alpha carbon attached to a carboxyl group, an amino group, a hydrogen and an R chain of variable composition, which determines the properties of the different amino acids; There are hundreds of R chains so hundreds of different amino acids are known. In natural amino acids, the amino group and the carboxyl group are attached to the same carbon that is called asymmetric alpha.
The binding of several amino acids results in chains called polypeptides or simply peptides. Protein will be discussed when the polypeptide chain exceeds 50 amino acids or the total molecular weight exceeds 5,000 amu. There are about 20 different amino acids composing proteins. The chemical binding between amino acids in proteins occurs through a peptide bond. This reaction occurs naturally in ribosomes, both of the endoplasmic reticulum and the cytosol.
