Are mutations in exons or introns more likely to result in an altered protein? - Exons Are mutations permanent or temporary changes in the DNA sequence? - Permanent changes in the DNA Avery - genes are composed of DNA , DNA (not proteins) can transform the properties of cells deletion mutation - a mutation in which one or more pairs of nucleotides are removed from a gene Does crossing over occur in mitosis? - No, only in meiosis Does meiosis result in diploid or haploid cells? - haploid ...

Largest to Smallest - Genome > Chromosome > Chromatin > DNA > Genes > Nucleic Acid DNA Polymerase III - synthesizes new DNA only in the 5' to 3' direction Leading Strand - has one primer Lagging Strand - has multiple primers Griffith - pathogenic pneumonia cells were able to transform non-pathogenic cells Chargaff - base composition varied from species to species and A-T and C-G complementation Hershey and Chase - concluded that the genetic material of the bacteriophag...

GCD Group Problems Test with Complete Solutions 1. From their experiments, Hershey and Chase concluded that the genetic material of T2 is DNA. Were there data consistent with the genetic material being RNA? If so, how could they have experimentally distinguished between DNA and RNA as the genetic material? You can assume that they had all types of radiolabeled bases (A, T, G, C and U) at their disposal. - Answer-Hershey and Chase used 32P, a radioisotope of phosphorus, to label DNA in T2 Phag...
