Studied by 6 peoplename the four biomolecules
carbs, protien, lipids, and nucleic acids
what is the function of DNA
it contains the instructions needed for an organisms develop survive and reproduce
what is the function of RNA
to carry proteins
where is DNA stored in the cell
inside the nucleus
name to polymers of nucleic acid
DNA and RNA
name the monomer of nucleic acids
nucleotides
A nucleotide is composed of three parts name those parts
phosphate sugar and nitrogenous base
name two structural differences between DNA and RNA molecule
ribose and deoxyribose
explain what it means to say DNA has complementary base pairs
guanine always binds with cytosine. and adenine always bind with thymine
what does DNA stand for
deoxyribonucleic acid
how many strands does dna have
two
what is the shape of dna
double helix/spiral staircase
the backbone of A double helix has alternating
sugar and phosphate groups
what bonds hold complementary bases together
hydrogen
in DNA the number of cytosines equals the amount of
guanine bases
in DNA the number of thymines equals the amount of
adenine
when during the cell cycle does DNA replication occur
The S phase
the ———- strand is made continuously
leading
the ——— strand is made out of segments, called
lagging, okazaki fragments
Which enzyme attaches new nucleotides to the original DNA strands
DNA polymerase
explain why the lagging strand of DNA is replicated the way that it is. Why is it different from the leading strand?
because the DNA is anti-parallel
