in a nucleotide, what is attached to the 3' carbon in deoxyribose? hydroxyl group (OH) to which carbon in deoxyribose is the phosphate group attached? 5' what does it mean to say that polymerization proceeds 5' -> 3'? DNA polymerase always adds nucleotides onto the 3' end of a DNA strand deoxynucleoside triphosphates (dNTP) Free nucleotides with three phosphate groups Breaking covalent bond to release pyrophosphate (two phosphates) provides energy to connect nucleotides dNTPs supply energy to polymerize DNA and they become nucleotides in the DNA phosphodiester bond connects successive nucleotides, links 3' carbon of one nucleotide to 5' carbon of another which base pair bond is stronger and why? GC bc they have more hydrogen bonds RNA a molecule closely related to DNA, is often used by cells to store short term information, can pair with DNA bases what are the two main differences between RNA and DNA? - thymine (T) is a base found in DNA but not RNA. in its place RNA incorporates uracil (U), it is a pyrimidine and pairs with adenine (A) - in RNA the 2' carbon is attached to a hydroxyl group (OH) instead of a hydrogen atom (H) so chemically speaking the sugar is ribose instead of deoxyribose what is the DNA sequence that is complimentary to the sequence 5'-TATTCG-3' 5'-CGAATA-3' in which direction does helices move along DNA? away from the origin of replication which of the following is generally rue about DNA within the replication bubble? it is single stranded what is the role of helicase? it separates the two strands of DNA in a double helix 00:02 01:28 primase synthesizes RNA in what direction is RNA synthesized? 5' to 3' direction what determines the nucleotide sequence of the strand synthesized by primase complementary base pairing with the original DNA why does primase only work in areas of DNA that have already been affected by helicase? the two strands of DNA must be separated by helicase before primase can bind with DNA DNA polymerase III synthesizes DNA by adding onto the 3' end
