Meropenem is an antibiotic. It fights bacteria in the body. Meropenem is used in the treatment of infections of the abdomen, such as appendicitis and peritonitis, bacterial meningitis (infection of the lining of the brain), and skin infections. Meropenem may also be used for purposes other than those listed here.
A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production. in the same places. But there are different versions of the same gene. Different versions of the same gene are called alleles (pronounced 'al-eels'). For example, the gene for eye colour has an allele for blue eye colour and an allele for brown. For any gene, a person may have the same two alleles or two different ones. Recessive or dominant alleles
Genes are sections of DNA, so many genes can be found along the lengths of DNA making up the chromosomes. All genes have more than one version, so when chromosomes are inherited from parent cells, the version of the gene, or allele, is not always the same. Although homologous chromosomes have the same genes, they do not have to have the same allele for each gene. If each chromosome of the homologous chromosomes pair has the same allele for a particular gene, it is said to be homozygous. If the alleles are different, then the cell is referred to as heterozygous. The way in which the alleles interact determines the characteristics of the offspring.
