nucleic acids test

biology

name 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
