The building blocks of protein
Cell parts
Chloroplast Cell wall Nucleus Nuclear me,brand Nucleolous Rna dna ribosomes Chromatin Endo plastic reticulum
Nucleus
Control center of cell contains DNA
Nuclear membrane
Double layered with pores

Types of Rna
mRNA
tRNA
rRNA
mRNA
Found in nucleus steals and copies Dna code to take it to the ribosomes
tRNA
Found in cytoplasm transfers amino acids to the ribosomes
rRNA
Found in ribosomes controls the making of a protein
Introns
Nitrogen bases that stay in the nucleus
Extrons
Nitrogen bases that leave the nucleus
Mutations
Change heredity
Change in chromosomes or genes
Transcription
Transferring the code from DNA TO mRNA
Translation
Produces proteins
Aerobic
Uses air low energy producing proces
Anaerobic
Low energy producing process does not use air
Isomer
each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties
Resolving power in microscope
Power of the microscope
Exocytosis
process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane
Endocytosis
taking in of matter by a living cell by invagination of its membrane to form a vacuole.
Cellular respiration formula
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
Naples number of chromosomes
23
Diploid number of chromosomes
46
Protein synthesis
the process by which amino acids are linearly arranged into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes.
Prokaryotic cells
Do not have a nucleus
Eukaryotic
Have nucleus
Carotines
Pigments in plants
Disaccharides
class of sugars whose molecules contain two monosaccharide residues.
Mutagen
an agent, such as radiation or a chemical substance, that causes genetic mutation.
First microscope
Robert Hooke
Studied cork
