Question

21. What amino acids are coded by the original DNA template sequence from question #8? Table of Genetic Code is found on last page of this document. 22. What is a frameshift mutation? 23. What is RNA splicing? 24. Where (in the cell) is RNA splicing conducted? 25. A gene contains introns and exons that make up the gene. Define “introns” and “exons”. Do the exons or introns code for the amino acids in the protein? 26. What are introns useful for? 27. Define “mutation”. 28. Define point mutation, insertion mutation, deletion mutation. Describe what is meant by “frameshift mutation”. 29. Look at the diagram and label where each step in gene expression would take place (transcription and translation). Label the nucleus, cytoplasm, membrane, and ribosome, and DNA. Circle the area where mRNA splicing is occurring.

Explanation / Answer

21. Can not be answered bz Q.8 not provided.

22. A frameshift mutation is a genetic mutation caused by deletion or insertion in a DNA sequence on That shift the way DNA reads.

23. RNA SPLICING IS THETHE PROCESS BY WHICG PRE nacent messenger RNA transcript introon are cut and exon are joined.

24. Splicing takes place in nucleus.

25. Introns are non coding region of DNA WHICH are cut off before RNA produce protein.

Exon are coding Part of DNA which forms coding RNA.

27. Muutation is suden heriable changes inn geenetic make up or heriditry material.
