Mutations Mutation a change in the nucleotide sequence of a gene Mutations can be triggered/caused by exposure to X-rays, ultraviolet light, radioactive materials, and some kinds of chemicals Types of DNA mutations deletion mutations, insertion mutations, and substitution mutations Each type of mutation changes _, which can cause a gene to code for a different _ than a normal gene the sequence of nitrogen base pairs, Instead, they code for the 1 ) beginning of a proteinģ) amino acid, end of the protein C. Translation The process of making a protein from RNA The order of the nitrogen bases in mRNA determines the order of the _ amino acids in a protein Codon Each series of three nitrogen bases on mRNA Most codons code for amino acids 1) One of the codons codes for an amino acid that is at the _Ģ) This codon signals that _ should start.ģ) Three of the codons do not code for any _. Transcription The process of making mRNA from DNA The three types of RNA transfer RNA, ribosomal RNA, and messenger RNA. RNA has the nitrogen base uracil (U), while DNA has thymine (T). RNA is single stranded and has the sugar ribose, while DNA is double-stranded.
Junk DNA Segments of DNA that are not parts of genes What is ribonucleic acid, or RNA? is a type of nucleic acid that carries the code for making proteins from the nucleus to the cytoplasm Compare deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) - RNA, like DNA, is made of nucleotides.
What does the DNA of each cell carry? a complete set of genes that provides instructions for making all the proteins a cell requires.
