What is the reason that closely linked genes are typically inherited together? - ANSWER The likelihood of a crossover event between these two genes is low All female mammals have one active X chromosome per cell instead of two. What causes this? - ANSWER Activation of the XIST gene on the X chromosome that will become the Barr body In his transformation experiments, what did Griffith observe? - ANSWER Mixing a heat-killing pathogenic strain of bacteria with a living nonpathogenic strain ca...

Griffith - transforming principle - streptococcus pneumonia - virulent strain has polysaccharide coat, have smooth coat (S) - R= rough, avirulent (lack coat) - some R could become S spontaneously Avery, MacLeod, McCarty - isolated transforming principle - destroyed different components, one at a time, to pinpoint which component was responsible for transforming DNA - found that DNA contained genetic material Hershey and Chase - T2 bacteriophage - radioactivity - protein ...

Chapter 9 review Latest questions 2024/2025 Questions and Answers 100% Solved Which of the following does cytosine pair with? guanine thymine adenine a pyrimidine - a. guanine Prokaryotes contain a ________chromosome, and eukaryotes contain ________ chromosomes. single-stranded circular; single-stranded linear single-stranded linear; single-stranded circular double-stranded circular; double-stranded linear double-stranded linear; double-stranded circular - c. double-strand...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frameshift mutations, includ...

Biology Midterm 2 Exam Questions With Verified Answers Which of the following shows the correct base pairing of deoxyribonucleotides that occurs in nature? Select one: a. A with T b. A with U c. A with C d. A with G - answerG pairs with C A pairs with T U is found in RNA, not DNA The correct answer is: A with T According to the "semi-conservative" model of DNA replication, after a double-stranded DNA molecule is replicated Select one: a. each DNA strand of each of the two result...
