DNA
What shape is DNA described as?
Double helix
What is Transcription?
The process of making a copy of the genetic information stored in DNA strand into a complementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
What is Translation?
Translation is the process of translating the sequence of a messenger RNA to a sequence of amino acids during protein synthesis.
What is protein?
Large molecules composed of one or more amino acids in a specific order determined by the base sequences of nucleotides in DNA coding for the protein
What is the amino acid cordon wheel?
An amino acid wheel is a quick easy reference tool to find which amino acid is translated from your RNA research.
What is DNA short for?
Deoxyribonucleic acid
Transcription is the _____ step in the process of making proteins.
First
Where does translation take place?
Ribosomes
"Building blocks of Proteins"
Amino acids
What is a full set of codons called?
genetic code
DNA contains what sugar?
Deoxyribose
What base is exchanged for Thymine during transcription?
Uracil or U
What are the four steps of translation?
Initiation, elongation, translocation and termination.
A protein consists of one or more _________ chains.
Polypeptide
Out of the 64 codons how many represent amino acids and how many represent stop signals?
61 codons represent amino acids
3 represent stop signals
DNA base pairs?
Adenine-Thymine
Cytosine-Guanine
Where does transcription take place?
Nucleus.
What happens in the first stage of translation?
Amino acids are brought to ribosomes and assembled into proteins.The correct amino acid is covalently bonded to the correct transfer RNA (tRNA). When the tRNA is connected to an amino acid, it is "charged".
Proteins are required for...
Proteins are required for the structure, function and regulation of the body's cells, tissues and organs.
Name all the codons that are stop signals.
UAA
UAG
UGA
Every human shares 99.9% of their DNA with every other human. True or False?
TRUE
What are the three stages of transcription?
initiation, elongation, and termination.
What happens in the second stage of translation?
Initiation is when the small part of the ribosome connects to 5' end of the mRNA with the help of initiation factors (IF).
What part of the cell makes protein?
Ribosomes
Match the correct amino acids to the following codons
CAG - AAG - UCA - CUU - GUA - UGU
Glutamine
Lysine
Serine
Leucine
Valine
Stop
