Molecular Biology - ANSWER The branch of biology that focuses on studying the molecules that create cells Started with the discovery of DNA Gene Expression - ANSWER The process of converting information in the DNA into molecules that do things Mutation - ANSWER A permanent change in the cells gene (DNA) Mutant - ANSWER The individual that carries the mutation Null Alleles - ANSWER Alleles that do not function One gene-one enzyme hypothesis - ANSWER Each gene has a function to m...

Ribozymes - ANSWER RNA molecules that function as enzymes Primary transcript - ANSWER the initial RNA transcript from any gene, including those specifying RNA that is not translated into a protein mRNA - ANSWER an RNA molecule that carries a genetic message from the DNA to the protein-synthesizing machinery of the cell template strand - ANSWER One of the two DNA strands (out of the two) that gets transcribed-- it provides the pattern or template for the sequence of nucleotides in an RNA...

What cellular events occur in the G1 phase of the cell division cycle? - ANSWER normal growth and cell function What is the best way to describe homologous chromosomes? - ANSWER they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - ANSWER Darwin's ...
