|
chromosomes
|
everything required for life; large complexes of DNA (bound by proteins)
|
|
|
3 Types of genes?
|
(a) structural genes= code for proteins (typically genes)
(b) RNA genes= just make RNA, not proteins (ex rRNA, tRNA) (c) Regulatory genes= control gene expression (=using a gene) |
|
|
Gene
|
made of DNA, fundamental unit of herdity make traits/characteristics by carrying info in proteins
|
|
|
histones
|
proteins that bind DNA
|
|
|
nucleosomes
|
histones and DNA wrapped together
|
|
|
chromatin
|
nucleosomes condensed together. All DNA packaged w/ proteins
|
|
|
Origin of Replication?
|
one per bacterial replication bubble
specific sequence in middle of replication bubble recognized by gyrase & helicase more at than gc |
|
|
tRNA
|
transfer RNA (transfers amino acids to growing, or nascent, peptide chain, or protein)
|
|
|
mRNA
|
codes for a structural gene (has info to make protein), caries DNA mastercode to ribosome
|
|
|
rRNA
|
ribosomal RNA; enzyme made of RNA, forms the peptide bond.
also removes entrons from RNA in eukaryotes |
