If the template strand for replication (the DNA strand that the DNA polymerase binds to and "reads") has the sequence 5'-AGGCTTCGCTCCCG-3' then the complementary strand synthesized by the DNA polymerase would be what ?
DNA is a double-stranded structure and the two strands are complementary to each other means A base pairs with T and C base pairs with G if G is present in one strand C is present in the corresponding location in the opposite strand similarly for A and T so the complementary strand is 3`-TCCGAAGCGAGGGC-5` ( two strands of DNA are antiparallel to each other)
If the template strand for replication (the DNA strand that the DNA polymerase binds to and...
1) The DNA template is read in the ______ direction, and the new strand is synthesized in the ____ direction. A) 5' to 3' ; 3' to 5' B) 5' to 3' ; 5' to 3' C) 3' to 5' ; 5' to 3' D) 3' to 5' ; 3' to 5' 2) If a sequence of DNA is 5' AATTGCCGT 3', the complementary strand would be A) 3' AAAACGCCA 5' B) 3' TTAACGGCT 5' C) 5' ACGGCAATT 3' D)...
If DNA polymerase adds a G across from an 'A' in the template strand during DNA replication (and it is not repaired/replaced), what kind of mutation results after the next round of replication? Briefly explain
Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.
If the sequence of the 5'-3'DNA strand is AATGCTAC, then the complementary DNA sequence has the following sequence o 3-AATGCTAC-5' 3'-CATCGTAA-5 3-GTAGCATT-5 3-TTACGATG-5 Question 2 20 pts Which of the following does the enzyme primase make? phosphodiester linkages (bonds) Okazaki fragments RNA primer DNA primer In which direction does DNA replication take place? 3'to 5 5'to 5 5'to 3 3'to 3 Question 4 20 pts Which enzyme unwinds the double-stranded helical DNA starting at the origin of replication? ligase primase...
Note that one of the two halves of the DNA molecule is labeled template strand and the other is the non-template strand. In protein synthesis, the RNA polymerase reads the template strand and uses it to make mRNA, filling in complementary bases. The mRNA then closely resembles the non-template strand. a. In what two significant ways do the non-template strand and the mRNA differ?

What is the primer in DNA replication? The first segment of template DNA that binds to primase. The primer is the dNTP that starts the reaction dNTP + DNAn → DNAn+1 + pyrophosphate. A short segment of RNA to which the growing DNA chain is bonded. A short sequence of DNA to which the growing DNA chain is bonded.
RNA polymerase binds to DNA after the double strands have been unwound by helicase. binds to the promoter region and synthesizes mRNA in a 3' to 5' direction. binds to the template strand in the promoter region. transcribes the poly A tail.
In order to sequence a strand of DNA, all four dNTPs, ddGTP, DNA polymerase and primers (5’ ACTGA 3’) are added to a test tube. A template strand of DNA is shown below. How many fragments of different lengths would you have at the end of the sequencing process? (write down the sequence of each fragment and the length of the fragment for full credit) DNA Sequence 3’ TGACTCTAGCCTAGGACTATATCG 5’
