The sickle form of the hemoglobin gene is created when an adenine nucleotide is changed to a thymine. ... That single amino acid replacement in the -globin protein alters the shape and the chemistry of the hemoglobin molecule, causing it to polymerize and distort the red blood cell into the sickle shape.
The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
<span>Both protexts the organisms' organelles which are inside the cell.
Animal Cell: Cell Membrane
Plant Cell: Cell Wall
Cell
wall is present only in plants, it is not found in all organisms.
Compared to the cell membrane, a cell wall is thick and has a rigid
structure. You can see it in a light microscope, because it is visible.
It serves as the protective cover that surrounds the plasma membrane in a
plant cell. Cell membrane is composed of lipids. Cell walls can be made
up of cellulose or peptidoglycan or chitin.<span> </span></span>
Explanation:
Possible anticodon sequences include: GCA, GCC, or GCU.
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other biological macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.
- Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.
DNA encodes an organism's genetic information; this undergoes transcription, where RNA is formed. Codons are three nucleotide bases encoding coding and amino acid or signal at the beginning or end of protein synthesis.
RNA codons determine specific amino acid, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made in translation; the four RNA nucleotides (Adenine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG Begins protein synthesis.In wobble pairing, the same tRNA can recognise different codons of its amino acid. Thus for the third positions on codons, alanyl-tRNA (inosine-guanine-cytosine) can recognise GCA, GCC, or GCU.

Well sickle cell disease requires two homozygous recessive alleles so you would have the disease but if your'e heterozygous you have the sickle cell trait.
