Gene Function
What is DNA?
Carries genetic information and is usually found in the nucleus.
What is the correct sequence of events for forming a protein
DNA → mRNA → Protein
Where does transcription take place?
In the nucleus
Transfer RNA
What are the three differences between DNA and RNA
1. Double strand (DNA) vs. single strand (RNA)
2. Different bases
3. Different form of sugar
What three things make up a nucleotide?
Sugar, phosphate, base
The DNA base Thymine is replaced by which base on an RNA strand?
Uracil
Transcription takes place between what?
DNA and mRNA
What tRNA anticodon would be needed to translate the sequence from mRNA codon?
U-A-G
A-U-G
What type of sugar does DNA have?
Deoxyribose sugar
What are the four DNA bases?
Adenine
Thymine
Cytosine
Guanine
DNA stands for
Deoxyribonucleic Acid
What must DNA to do first to make an mRNA strand?
What is a chain of amino acids called
Polypeptide chain
What kind of sugar to RNA have?
RNA has ribose sugar.
The process in which one DNA molecule forms into two DNA molecules
DNA replication
RNA stands for
Ribonucleic Acid
What mRNA baes would match with this DNA triplet?
G-A-T
C-U-A
Translation takes place between what?
mRNA and tRNA
What is the shape difference in DNA and mRNA?
DNA is a double Helix, RNA is a single stranded or helix.
What are 2 processes or steps of protein synthesis called?
Transcription and Translation
A codon is a sequence of how many bases?
3 bases
What organelle must an mRNA attach to before protein production can begin?
a ribosome
What is the difference between an amino acid and a protein?
Amino acids are the building blocks of a protein. A protein is a chain of amino acids that are connected to each other.
Where is DNA and mRNA located at?
DNA is found in the nucleus, mRNA is found in the nucleus, cytoplasm, ribosome
