What do tRNA, mRNA, and rRNA stand for?
Transfer RNA, Messenger RNA, ribosomal RNA
True or False: DNA is a double strand
True
Translate the DNA code: AGGATAG into a mRNA
UCCUAUC
True or False: RNA is single stranded macro molecule.
True
What is the role of tRNA during translation?
A. bond to open the DNA strand to carry the code for protein synthesis out of the nucleus
B. bring ribosomes to the site of protein synthesis
C. break apart mRNA and send it back to the nucleus so that it can be reused
D. Carry amino acids to the mRNA for correct placement into the protein chain
Answer: D. Carry amino acids to the mRNA for correct placement into the protein chain
Define transcription.
What unzips DNA
DNA helicase
What Makes up DNA?
DNA Nucleotides
What is the role of the tRNA in protein synthesis?
tRNA helps decode (mRNA) sequence into a protein and carries amino acids.
What is translation?
Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
What are the three kinds of mutations?
Deletion, addition, and subsitution.
What holds the DNA base pairs together?
Hydrogen bonds
How many main RNA types are there?
3 types
What is the role of the mRNA in protein synthesis?
mRNA is a single-stranded molecule that carries genetic code from DNA in a cell's nucleus to ribosomes, the cell's protein-making machinery to code for proteins
What's the word? The passing on of physical or mental characteristics genetically from one generation to another.
Why Is DNA Called Deoxyribonucleic Acid?
The name comes from its structure, which is a sugar and phosphate backbone which have bases sticking out from it--so-called bases. So that "deoxyribose" refers to the sugar and the nucleic acid refers to the phosphate and the bases.
Who Discovered the structure of DNA?
Hint: More then One person.
James Watson and Francis Crick.
How much total mRNA does RNA contain
1-5% total mRNA
What Main RNA is not required during protein synthesis?
What is a peptide bond?
The chemical bond formed between the carboxyl groups and amino groups of neighboring amino acids, constituting the primary linkage of all protein structures.
Can a cleft chin be a result of DNA crossing over?
Yes
