Flashcards in Chapter 8 Deck (43):
Study of what genes are, how they carry information, how information is expressed, and how genes are replicated.
All the DNA in organism
Structures compressed of neatly packed DNA molecule.
How many chromosomes do humans have?
How many chromosomes do bacteria have?
1 or 2
Segment of DNA that encodes a functional product (protein or RNA molecule)
What are the 3 types of genes
-Structural genes (proteins)
-Genes that code for RNA
-Regulatory genes (control gene expression)
Code of DNA. A, T, C, G.
Expression of genes. (Black hair, curly hair, eye color, etc....)
A plasmid is an independent, circular, self-replicating DNA molecule.
What are the Nitrogenous bases?
How do the Nitrogenous bases bond in DNA?
What is the 'backbone' of DNA
How are the strands of DNA held together?
By H bonds.
What is the name of Sugar for DNA
What is the name of Sugar for RNA
How do the Nitrogenous bases bond for RNA?
Types of Plasmids?
The copy of DNA into two daughter cells that are exactly the same.
One strand in DNA replication acts as template.
One daughter cell gets the new, one gets the old.
Opens strand of DNA in replicaiton
Adds nucleotides in DNA replication.
Adds primer (RNA) In DNA replication
Seals gaps in DNA replication
DNA Nucleotides are what ratio?
Which DNA strand has Okasaki fragments?
The lagging strand
What are the two stages of proteinsynthesis?
Making of messenger RNA from a segment "Gene" of DNA.
DNA or RNA polymerase. Has proofreading?
Types of RNA transcribed from DNA
The making of protein through mRNA
Stop codons are also called what?
Mutation that occurs but does not change the amino acid being synthesized.
tRNA binding sites. What happens in site A?
Arrival of codene. All but the first.
tRNA bingding sites. What happens in site P?
Protein growth. First codene comes here
tRNA binding sites. What happens in site E?
Where does translation occur?
On the Ribosomes
Change in the nucleotide base sequence of a genome, rare.
Decendents of cell that does not successfully repair a mutation
