What does DNA do? - ANS ✔✔Stores the information that the cell needs to produce proteins
What is DNA made of? - ANS ✔✔nucleotides
Each nucleotide consist of - ANS ✔✔Phosphate, deoxyribose, nitrogenous base
4 nitrogenous bases - ANS ✔✔Adenine, Thymine, Guanine, Cytosine
DNA strands are what? - ANS ✔✔complementary and antiparallel
5-prime - ANS ✔✔Where the phosphate group is attached to deoxyribose
3-prime - ANS ✔✔Where the OH group is attached to deoxyribose
DNA nucleotide bases - ANS ✔✔Adenine, Thymine, Guanine, Cytosine
RNA nucleotide bases - ANS ✔✔adenine, guanine, cytosine, uracil
What is DNA stranded? - ANS ✔✔Double stranded
What is RNA stranded? - ANS ✔✔Generally single stranded
RNA does what? - ANS ✔✔Carrie's protein and coding information and helps make proteins
Genome - ANS ✔✔all of an organism's genetic material
Gene's - ANS ✔✔Short segments/sequences of DNA that code for a specific protein, trait, or RNA
molecule
Chromosome - ANS ✔✔Tightly coiled up/pack DNA, wrapped around proteins, called histones
Nucleus - ANS ✔✔Each nucleus contains 6.4 billion base pairs of genetic information
The Central Dogma - ANS ✔✔They flow of genetic information in which DNA makes a protein
DNA is transcribed into what? - ANS ✔✔RNA sequence
RNA is translated into what? - ANS ✔✔Amino acid codes
Elongation - ANS ✔✔RNA polymerase moves/read along the template strand from 3 to 5
Introns - ANS ✔✔Sequences and genes that are not used for producing a protein and are removed from
the mRNA
