4.) During DNA replication, the two strands of DNA are pried apart and then serve as templates for synthesis of new strands. However, there are some big differences in how the two strands are copied. Why is this so? Please describe in 4-5 sentences of your own words how replication proceeds on the two strands.

1. Describe the process of autophosphorlyation 2. Differentiate between chromosomes and genes. 3. Think about what happens at the replication fork. If the gene for helicase is mutated, what part of replication will be affected and how? 4. There are three common types of chemical changes that can damage DNA at any time post-replicatively. In basic terms, name and describe any two of the three types of damage.    please help me quick

K The template (antisense) strands of two complete (double-stranded) DNA molecules have the base sequences shown in the table below. Two replication experiments are done with each molecule: 1. In Experiment #1, samples of each DNA molecule are incubated with radioactive cytosine, along with appropriate replication enzymes, ATP, adenine, thymine, and cytosine. Experiment #1 is stopped when each DNA molecule has replicated once. 2. In Experiment #2, all the DNA molecules from #1 are purified, and then incubated with with a similar reaction mixture - except non-radioactive cytosine is used this time. Experiment #2 is stopped when each DNA molecule has replicated one more time. Predict the percentage of DNA in each sample that is radioactive after each experiment.

DNA polymerases are processive, which means that they remain tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter stand. Which piece of the replication machinery accounts for this characteristic? Helicase Sliding Clamp Single Stranded Binding Protein Primase

A. DNA Replication Construct a DNA with 15 base pairs. (Note that the first three nucleofides of the parent DNA (3' to 5') strand correspond to a start codon and its last three nucleotides correspond to a stop codon in its MRNA counterpart later on.) Write it down as follows: a. the sequence of parent DNA (template) 3' A C A TT 5' 3' Upon undergoing DNA replication, show what one daughter DNA molecule will look like. Write it down as follows: b. the sequence of DNA Daughter 1: 3' 5' 5' 3' C. the sequence of DNA Daughter 2: 3' 3' 5' in in

All guanines in the top strand of the following sequence are converted from the 'keto' tautomer to the 'enol' tautomer, resulting in pairing with thymine. (top strand) 5' TAGCATGCAA 3' (bottom strand) After a few rounds of replication, what will the sequence of the mutated top strand be? (5' to 3') (Newly incorporated nucleotides are in the 'keto' form.) 3' ATCGTACGTT 5'

14. Guanine normally pairs with cytosine. Oxidative damage can result in the modification of guanine to 8-oxoguanine. What is the potential mismatch in nucleotides that can occur following replication? 8-oxoguanine pairs with Adenine 8-oxoguanine pairs with thymidine Thymidine pairs with adenine Guanine pairs with Cytosine None of these choices. Question 8 The key enzyme that transfers an a-amino group from an amino acid to an a-keto acid is : Glutamate Dehydrogenase Transaminase Synthetase Glutamine PRPP Amidotransferase Glutaminase
