How are genes encoded
WebB) Different alleles may produce differences in the phenotype of an organism. C) The set of alleles for a given trait carried by an organism is called the phenotype. D) A population can contain many alleles for a gene, but an individual diploid organism has only two alleles for a gene. A, B, C. Chapter 1 - Homework. WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.

WebHomeotic mutations in fruit flies. Homeotic genes are responsible for determining the identity of particular segments or structures of the body. So, when homeotic genes are inactivated or expressed in unusual locations due to mutations, they may cause body segments to take on new—and sometimes startling!—identities.
