PPT-MUTATIONS WHAT HAPPENS IF DNA HAS ERRORS?!!!

What is the relationship between an organisms DNA and protein specificity DNA becomes a specific part of the protein structure DNA determines the ribosomal RNA sequence that becomes part of the protein structure. Mutations. What do you think a mutation is?. What happens to you during a mutation?. Mutations. Mutations. are ANY change in an organism’s DNA.. Mutations usually happen during if a mistake is made during replication (S phase).. Unit 7. Chapter 12. DNA. D. eoxyribo. n. ucleic . A. cid. RNA. R. ibo. n. ucleic . A. cid. Where does DNA “live”?. The NUCLEUS!. Why is DNA so Important?. * . DNA i. s a nucleic acid that contains the genetic information used in the development and functioning of all living things and some viruses.. Mutation. Permanent change in the genetic material of an organism. All mutations in gametes are inheritable because they are copied during DNA replication. Somatic cell mutations occur in body cells. and Causes. What kinds of mutations can occur?. Mutations:. Mutations: are changes in the genetic material.. Mutations can produce changes in a single nucleotide to a whole chromosome. . Gene Mutations:. Polypeptides made up of amino acids. Proteins are polypeptides, numerous amino acids. First Recall Proteins------. **Peptide Bond between amino acids. **Notice the “R” group. It’s a group of molecules that determines the amino acid.. Point mutations. single base change . silent mutation. no amino acid change. redundancy in code. missense. change amino acid. Changes the final protien. nonsense. change to stop codon. Stopping prematurely . Given a mutation, identify its type. Predict how a mutation will affect a protein.. Mutations. Changes in genetic material (DNA). 2 main types of mutations. Point mutation- change in one or a few nucleotides (letters). The sequence of bases in DNA are like the letters of a coded message or even the letters of a simple alphabet. . If we change the sequence of the letters do we change the nature of the message?. That . How does it happen???. Environmental Influences . such . as: . Chemicals or UV Rays. Inherited: mutations can be passed down from . parent. to . offspring. During copying of . DNA. , . mistakes. can occur. Small-scale mutations. Missense mutations. Nonsense mutations. Silent mutations. Frameshift mutations. Large scale mutations. Causes. Mutagens. The results of mutation. Mutations. Genetic mutations are changes in the DNA sequence, caused by various mechanisms.. The types of proteins an organism possesses depend upon the . sequence of nucleotides. The two main types of gene mutations include:. Point mutation: one base pair is replaced for another base pair.. Mutations. Mutation. : a . change. in DNA. -not all mutations are harmful . -can happen in body cells and in gametes.. . **. mutations are . passed down. to offspring only when they are in the . Science. Learning intention. To understand the different types of mutations. . You will need. A pen and a piece of paper or a laptop to record your answers. .
