Answer:
one "A" or one "a"
Explanation:
In diploid species (2n), each individual inherits two gene variants (alleles) for each gene, one from the father and one from the mother. This means that each haploid gamete (n) receives one copy of each homologous chromosome that contains only one form of that gene (i.e., one allele). In consequence, and according to Mendel's First Law, alleles segregate into separate gametes (in this case either "A" allele or "a" allele since the parental genotype is heterozygous for this gene).
Mitosis and meiosis
The statement is true. While mitosis's main function is to repair and grow, meiosis fulfills its function in reproduction, forming the egg and the sperm, the cells involved in the fecundation to form a new individual.
Glucose is a complex carbohydrate classified as a monosaccharide,<span>an aldose, and a hexose.</span>
Answer:
The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers. ... Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.
Explanation:
Answer:
The main difficulties of X-ray crystallography include:
1. It is very difficult to obtain crystals with high diffraction quality and proper size.
2. Phase analysis. In theory, X-ray crystallography technology has no requirement for the molecular weight of protein, and can obtain any high-resolution structure at the atomic level of protein. Because some proteins are very difficult to crystallize, or the quality of crystallization is very poor, there is no diffraction or only very low resolution diffraction data, which limits the X-ray crystallography analysis of protein structure.
