Mr. Satinoff Tuesday, January 10th test. A + WON!!!
Acronym for DNA stands for?
What is the sugar that makes up the backbone called?
Thymine, Cytosine, Adenine and Guanine
What are the 4 nitrogen containing bases of DNA?
Cytosine and Thymine
Which of the bases are single ringed pyrimidines?
Adenine and Guanine
Which of the bases are double ringed purines?
What base matches with cytosine in DNA?
Which base matches with adenine in DNA?
What is the shape of DNA?
Weak Hydrogen Bonds
What bonds hold the nitrogen containing base pairs together in the center of the molecule of DNA?
What type of bond holds the nitrogen containing bases to the sugar/phosphate backbone of the DNA molecule?
The process of copying or making new DNA is called?
What enzyme breaks the bonds in the center of DNA to unzip the molecule or separate the chains of DNA?
The point at which the 2 chains of DNA separate
Moves along the 2 separated chains, new chains are assembled complimentary to the existing chain.
Consists of a sugar, phosphate, and nitrogen containing base pair.
A change in a nucleotide sequence
The acronym RNA stands for
The sugar in RNA
Instead of thymine, an RNA molecule contains this base
What does adenine match with in RNA?
What does guanine match with in RNA?
mRNA stands for
Single strand 1/2 ladder
The structure of mRNA is what shape?
Carries genetic information from DNA to ribosome
tRNA stands for?
Writes the code from mRNA and ensembles amino acids into polypeptide chain proteins
rRNA stands for?
rRNA + Protein = Ribosome
Process of making a strand of mRNA from DNA is called?
Where does translation occur?
Where does transcription occur?
The process of assembling polypeptides from mRNA (making proteins) is called?
What is composed of rRNA and proteins, they are free in the cytosol and attached to the rear.
When the mRNA leaves the nucleus to go to the ribosome, from where does it leave?
Start codon that engages the ribosome to being translation
UAA, UAG and UGA
Stop codons that cause the ribosome to stop translation
Each combination of 3 nucleotides is called a?
Each codon codes for a specific what?
Divide by 3 = 5
If a chain of bases is 15 nucleotides in length how many amino acids could be produced?
Amino acids form a polypeptide chain also known as a what?
Replication, Transcription, Translation
Protein synthesis order? (Alpha)
How many carbons in a purine?
How many carbons in a pyrimidine?
What is double carbon?
What is single carbon?
Holds amino acids together to make proteins
Enzyme that zips hydrogen bonds
What occurs in the nucleus ONLY!!!?
What is 60% of a humans dry weight?
1 amino acid
Every 3 bases=?
3 amino acids = how many base pairs?
Percent of bases must equal?
