1. In a phylogenetic tree, common ancestor is known as internal nodes where two branches meet and hence, option a is correct.
2. (Sex) influenced trait are affect only one (sex). Hence, option e is correct.
3. The mutation are common more in nuclear DNA than the mitochondria DNA. Hence, option c is correct.
4. (Sex ) limited traits are present in both male and female but express only in one. Hence, correct option is c.
5. STR stand for short tandem repeats and are short repeats found in DNA. Hence, correct option is e.
6. Stem cell are unique because they have a ability to self-renew . Hence, option d is correct.

Question 15 1 pts To study DNA replication, researchers often use bacteria that harbor a temperature sensitive mutation in one of the genes related to replication. This means that when cells are grown at lower temperatures (30°C) they are fine, but when shifted to 42°C the effect of the mutation becomes evident and that protein is no longer functional. Depending on the gene mutated, researchers observe that for some replication stops almost immediately, but for others more slowly. In this...

Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...
16. Which of the following enzymes adds DNA to the ends or material with duplication? a. Telomerase b. Polymerase d. Primase e. Ligase 1. Which of the following structures indicates where DNA replication begins a. DNA polymerase III b. Replication fork C. Helicase d. Origin of replication e. Centromeres 18. A select mutation is causing a cell lineape to be unable to replicate DNA SUccessfully NA successfully. When observed under a microscope, researchers observe that the DNA is able to...
Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...
Identify the correct statements about mutations. Choose all that apply. A. An individual with PKU would need to take a supplement of phenylalanine since they are missing the enzyme that synthesizes phenylalanine from metabolic precursors. The number of mutations resulting from the incorporation of incorrect bases during DNA replication is reduced through the use of a 3'-51 exonuclease. Cells with wild-type copies of CFTR are likely to have a lower concentration of Cl- than cells with mutated copies of CFTR....
Which of the following statements is true? A. RNA polymerase has a proofreading activity B. Prokaryotic RNA usually undergoes nuclear processing C. Polypeptides are synthesized by addition of amino acids to the amino terminus. D. The 3' end of mRNA corresponds to the carboxyl terminus of the protein. Grade 2. Which of the following A. It may be autocatalytic. B. Spliceosomes are present in organelles and nuclei C. It involves removal of exons is true regarding RNA processing? D. It...

Which of the following statements are true? (hint: There might be more than one True statement) © Multiple answers: You can select more than one option O A Exons are intervening regions in genes O B Enhancers might be present in the middle of a gene oc RNA polymerase translates mRNA into protein O D Poly Atails are added to the 5' (five prime) end of mRNAs O E Enhancers might be present downstream of a gene
Question 6 A person can be a “carrier” of sickle cell but not have the disease. How is this possible? 1 points Question 7 Scientists James Watson and Francis Crick determined the double helix structure of DNA. Why is that structure important in DNA replication? A. When the DNA separates into two halves during replication, each half is a mirror image of the other, so the new halves fit right back together again in the new cell. B. The structure...
Chapter 21,23 Read the following statements about the role of chance in evolution. Identify each statement as TRUE or FALSE. 1.The ultimate source of new alleles is mutation, random changes in the nucleotide sequences of an organism’s DNA. 2.Evolutionary change proceeds by an accumulation of changes that occur by chance. 3.An allele may be lost from small populations due to chance events unrelated to the fitness consequences of the allele Chapter 24 1.Identify each statement as TRUE or FALSE. a.Speciation...
