21. Single nucleotide polymorphisms (SNPS) mutations are rarely fatal. Which of the following is not an explanation of this fact? a. only about 2 % of the human genome codes for proteins b. many genes are not expressed in most cells c. there are two copies of a gene present d. most SNPS do not code for an extremely important part of a protein e. all of the preceding are satisfactory explanations as to why SNPS are rarely fatal.

28. Approximately 50 % of the human genome is composed of  a. protein-coding genes b. ribosomal RNA genes c. mobile genetic elements like transposons and retrotransposons d. introns e. promoter sequences.

1. Determine the effect of the following mutations on the DNA sequence. In each case, the mutation is described after the sequence (REFER TO THE SUPPLEMENTAL DOCUMENT FOR GUIDANCE TO THIS QUESTION). Adenine nucleotide (A shown in red below) was inserted into the DNA sequence at the position indicated by the arrow). Write out the sequence of the mutated DNA and the protein made from it. What is the effect of this mutation on the protein? (For example, how will the mutation affect the length and sequence of the protein? What about the function of the protein?)

If a gene is mutated, then it may consequently affect the expressed in the central dogma which then may lead to alter the production/function of other bio-molecules. Select one: a. lipids b. carbohydrate С. DNA Ca d. protein Do Is w Wha ( Previous page Next page https:// Jump to... What Mar 13.
