How can only four bases in RNA carry instructions for 20 different amino acids?
The properties of proteins are determined by the order in which different amino acids are joined together to produce polypeptides. The genetic code is read three letters at a time, so that each "word" of the coded message is three bases long.
What acids make up a protein and how do they contribute to the structure and function of the protein?
Proteins are made up of amino acids. There are 20 different amino acids that can be found in proteins. These amino acids contribute to the structure and function of proteins by forming specific sequences that determine the protein's shape and function. The unique arrangement of amino acids in a protein allows it to carry out specific biological functions in the body.
What is composed of long chain of amino acids?
Proteins are composed of long chains of amino acids. These amino acids are linked together by peptide bonds to form polypeptides, which then fold into specific three-dimensional structures to carry out various functions in the body.
What element transports and positions amino acids?
The element that transports and positions amino acids is tRNA (transfer RNA). tRNA molecules carry specific amino acids to the ribosome during protein synthesis and ensure that the correct amino acid is added to the growing polypeptide chain according to the sequence of mRNA.
Polymers of amino acids are?
Polymers of amino acids are proteins. Amino acids are linked together by peptide bonds to form long chains, which then fold into unique three-dimensional structures to carry out specific functions in living organisms. Proteins are essential for a wide range of biological processes, such as enzymatic reactions, cell signaling, and structural support.
What carry instructions for making proteins?
mRNA
What is the function of the messenger rna?
The function of messenger RNA is to carry copies of the instructions for assembling amino acids into proteins to the rest of the cell or, more specifically, to the ribosomes.
What Cells carry amino acids?
All Cells carry, contain and control all sorts of proteins that are comprised completely from Amino acids.
How can only four bases in RNA carry instructions for 20 different amino acids?

Does DNA code carry instructions the correct sequence of nucleic acids in a protein?
Yes, DNA carries the instructions for the correct sequence of nucleic acids in a protein. These instructions are encoded in the DNA molecule as a specific sequence of nucleotide bases (adenine, thymine, cytosine, and guanine). Through a process called transcription, the DNA sequence is transcribed into a messenger RNA (mRNA) molecule, which is then translated into a specific sequence of amino acids to form a protein.
What carries amino acids?
All Cells carry, contain and control all sorts of proteins that are comprised completely from Amino acids.
What is the RNA's messenger function?
The function of messenger RNA is to carry copies of the instructions for assembling amino acids into proteins to the rest of the cell or, more specifically, to the ribosomes.
A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?
The smallest number of bases needed would be 300 bases, as each amino acid is coded for by a sequence of three bases (codon) in mRNA. Therefore, 100 amino acids x 3 bases per codon = 300 bases in the mRNA molecule to code for the protein.
How can only four bases in rna carry intructions for 20 different amino acids?
It takes a set of three RNA bases to code for one amino acid. Since there are 4 different bases in RNA, there are 4 x 4 x 4 = 64 possible combinations. This is many more combinations than is necessary to code for 20 amino acids. The reason that there are more than 20 is that some combinations code for the same amino acid.
What does tRNA carry from the cytoplasm to the ribosomes-?
Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins.
What are four bases in RNA carry instruction for 20 different amino acids?
those are A (adenine) paired with U (uracil) and vice versa, and C (cytosine) paired with G (guanine) and vice versa. T (thymine) is replace by U in RNA. mRNA carries the transcribed DNA out from the nucleus and go to ribosomes which is then 'translated' by matching the codon with anticodons attached in the tRNA which carry the correct amino acid.
Which type of biomolecules are composed of amino acids?
Proteins are biomolecules composed of amino acids. Amino acids are linked together by peptide bonds to form protein chains, which then fold into specific three-dimensional structures to carry out various functions in the body.
