Which are segments of DNA that code for specific traits?

A. genes

B. chromosomes

C. proteins

D. codons

Answer – A. genes.

Genes are considered to be the important segments of DNA which provide codes for the specific traits, functions or the characteristics within living organisms. Genes are an important unit related to heredity that are mainly located on the chromosomes within the cells. Each of the genes have codes form the specific proteins or parts of the proteins which influence the traits like skin pigmentation, eye color, the immunity system and the hormone production. Genes can be transcribed within the RNA molecules and are translated for development of proteins. AUG codon can be the “start” codon which leads to beginning of the protein and thereby codes for amino acid methionine. Most of the codons specify the amino acids and the “stop” codons lead to ending of the proteins. Decoding the messages is considered to be an important step within gene expression within the information gained a specific gene is read properly for building the protein. The closer look based on genetic codes can help in creation of the RNA and the DNA sequences which can be effectively decoded into amino acids that are a part of the protein. Gene which can provide the instructions for the proteins can be expressed by using two different steps that include transcription within which DNA sequence of the gene can be rewritten within the RNA and the RNA needs to go through the additional processing-based steps for becoming a messenger RNA or mRNA. Another step within this process is termed as translation which is sequence of the nucleotides within the mRNA and can be translated within the sequence related to amino acids in the polypeptide. The genes are considered to be important parts of the DNA which provide a clear picture based on the specific traits.
