| Viruses that infect bacterial cells |
|
|
Term
| Monomer unit of DNA and Rna |
|
Definition
| It's the nucleotide and it contains a nitrogenous base, a 5-carbon sugar, and a phosphate group. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Formed by covalent bonding between the phosphate of one nucleotide and the sugar of the next nucleotide |
|
|
Term
| James D. Watson and Francis Crick |
|
Definition
| Deduced the seondary structure of DNA, with x-ray crystalllography data from Rosalind Franklin and Maura Wilkins |
|
|
Term
|
Definition
| Composed of two polynucleotide chains joined together by hydrogen bonding between bases, twisted in helical shape. |
|
|
Term
|
Definition
-Two strands separate
-each strand is used to pattern a complementary strand, using specific base pairing
-each new DNA has a new strand and an old strand
It begins at origin.
-Unwinds at origin to produce bubble
-Replication proceeds in both directions from the origin
-Replication ends when product from bubbles merge with each other |
|
|
Term
| Proteins involved in DNA Replication |
|
Definition
-DNA plymerase adds nucleotide to growing chain
-DNA ligase joins small fragments into a continuous chain |
|
|
Term
|
Definition
| DNA separates, RNA uses specific base pairing, RNA polymerase catalyzes the reaction |
|
|
Term
|
Definition
Initiation: RNA polymerase binds to a promoter
Elongation: RNA nucleotides are added to the chain
Termination: RNA plymerase reaches a terminator sequence and detaches from template. |

|
Term
|
Definition
| Codons for protein sequence |
|
|
Term
|
Definition
| Molecules match an amino acid to its corresponding mRNA codon. |
|
|
Term
|
Definition
| Allows tRNA to bind to a specific mRNA codon, complementary in sequence. |
