You are studying replication and isolate the molecules needed to replicate DNA. You mix the molecules together with some DNA, replication occurs but each DNA molecule consists of a normal strands except you notice that there are small RNA molecules in both strands. What did you leave out?      DNA Polymerase I DNA Polymerase III Primase Ligase None of the choices, I've discovered a new type of replication!!!

Which of the following enzymes has a major role in joining of DNA fragments (Okasaki fragments) during DNA replication? Group of answer choices DNA gyrase Helicase Primase DNA polymerase DNA ligase

I struggled with my homework

answer above is wrong, need help identifying which one is right.  Thanks!

Which of the following things must happen first if DNA is going to be replicated * DNA gets broken into smaller pieces to make the process more manageable DNA gets unzipped, so the two complimentary strands are separated DNA Polymerase adds on bases that match with the original strand DNA gets wound back into chromosomes so it's ready for mitosis Lenovo esc -> 女 # 2$ 2 3 5 6 7 8 9. tab e r t y a f k ift V alt ctri

Given the replication events listed below which even takes place first Single Strand binding proteins bind Primase adds an RNA primer Helicase unwinds the DNA double helix  DNA polymerase begins adding DNA nucleotides

A friend asks for help understanding replication for the next biology test. (S)he draws a replication bubble for a DNA molecule being replicated. The origin of replication is shown (0) and newly replicated DNA is shown as gray.  Small gray arrows represent okazaki fragments. Solid gray lines represent leading strand. Draw a corrected version of a replication bubble below.

Why do we find multiple, short RNA pieces inserted into the lagging DNA strand during DNA replication?   Question 43 options:   the DNA polymerase is replaced by the RNA polymerase in these regions for unknown reasons   the DNA polymerase doesn't copy flawless and adds sometime uracil instead of thymine to the growing daughter nucleotide strand   multiple RNA primers have been added with the help of the primase enzyme to create multiple start sites for  the DNA polymerase   Retroviruses sometimes like to insert their RNA into the replication fork and favor the lagging strand   multiple RNA pieces are most likely found in the leading not the lagging strand during DNA replication

This is a homework question.

Which of the following DNA repair processes is known to be "error-prone" (i.e. resulting in incorporation of incorrect nucleotides as part of the repair process)? Mark all the answers that are correct. Base Excision Repair (BER) non-homologous end-joining of double-stranded DNA breaks. O Nucleotide Excision Repair (NER) post-replication repair SO-response
