What is a Genome
|
All the genetics information in a cells DNA
|
|
|
Genetic information is?..
|
DNA and RNA
|
|
|
What does DNA stand for?
|
Deoxyribonucleic acid
|
|
|
what does RNa stand for?
|
Ribonucleic acid
|
|
|
How many carbons does RNA have?DNA?-how do they differ?
|
RNA is a 5carbon sugar, so is DNA except DNA is missing an OH group
|
|
|
Describe DNA
|
Very long thin molecule used as a code for cells to construct proteins.
|
|
|
Where can DNA be found?
|
For a Eukaryotic cell it can be found in the nucleus and mitochondria. For a Prokaryotic cell it is located in the nucleic region.
|
|
|
What are genes?
|
Genes are segments of DNA
|
|
|
What do ribosomes do with DNA codes?
|
They read the code and then are able to bond the amino acids together in the correct order.
|
|
|
What are all the structure parts that make up DNA?
|
1.Deoxyribose sugars
2.Phosphate groups(PO4) 3.4 diff. bases: -Adenine -Guanine -Thymine -Cytosine |
|
|
What do ribosomes do with DNA codes?
|
They read the code and then are able to bond the amino acids together in the correct order.
|
|
|
Would you say DNA is parallel?
|
No DNA is antiparallel, with a 5'-3' end
|
|
|
How does Adenine and Thymine pair together?
|
A-T pair using 2 hydrogen bonds
|
|
|
How many hydrogen bonds does it take for cytosine and guanine to pair up?
|
three
|
|
|
How is the DNA in Prokaryotic cells shaped?
|
Only One circular DNA molecule
|
|
|
How are Eukaryotic DNA composed?
|
In eukaryotic cells DNA molecules are linear and are divided into multiple segments called chromosomes.
|
|
|
Name all the structural parts of RNA
|
RNA unlike DNA is SINGLE stranded. It has 6 pts.:
1. Ribose sugar 2. phosphate group 3.and 4 diff. bases: -Guanine -Cytosine -Adenine -Uracil |
|
|
What are the 3 different kinds of RNA molecules?
|
1. mRNA;messinger RNA
2. tRNA;transfer RNA 3. rRNA; ribosomal RNA |
|
|
How is mRNA made?
|
DNA is copied
|
|
|
What is mRNA's job?
|
Take copy of coded info frm DNA and deliver to ribosome so it can be made into protein
|
|
|
WHere is rRNA located?
|
rRNA is located inside a ribosome
|
|
|
What does tRNA do?
|
It is the translation tool that decodes mRNA and creates a protein.
|
|
|
What is a charged tRNA?
|
A charged tRNA means that an amino acid is attached to the top of it, theres a diff tRNA for each amino acid.(total 20)
|
|
|
What is an anticodon and where can it be found?
|
An anticodon can be found at the bottom of a tRNA and is 3 bases long and attaches to a corresponding sequence on the mRNA.Theres a fifferent anticodon for each amino acid.
