Organic Molecules
What is an organic compound?
Molecules that work with living things.
How many cell division are there in Meiosis?
Two cell divisions.
What is a major event of prophase?
Chromosomes begin to condense.
What is translation?
RNA controls the production of proteins forming proteins based on information in DNA.
What is transcription?
DNA acts as a template for the synthesis of RNA.
What are amino acids?
Building blocks of protein.
When does the DNA remake itself?
Interphase
What is the final phase of mitosis?
Telophase
Three types of RNA
mRNA tRNA rRNA
What is a gene?
DNA which codes your genetics.
What are isomers?
Have same chemical formula but different shapes.
What is crossing over?
Crossing over is when genes do a genetic exchange.
How long does mitosis take?
2 Hours
How is RNA different from DNA?
RNA contains surgar ribose not deoxyribose
usually single stranded
Much shorter in length than DNA
Track progress
What does mRNA do?
RNA molecule that carries the instructions from one gene to make a protein.
What are proteins made up of?
Long chains of amino acids.
When does crossing over occur?
Prophase 1
What structure guides the movement of chromosomes?
Spindle fiber.
What does tRNA do?
Transfers amino acids to the ribosome to make a protein.
What are the two main flows for genetic information?
Transcription and Translation
What is a disaccharide?
When two monosaccharides come together.
What are centromeres?
What holds the chromosome together.
What is a major event of prophase?
Chromosomes begin to condense and spindle fibers start to form.
What does a tRNA do?
Transfers amino acids to the ribosome to make a protein.
What is the 1st step of transcription?
RNA polymerase binds to a promoter, after promoter binds DNA strands unwind and seperate.
