What is an anticodon
The triplet of bases in the center loop of tRNA that is complementary to a codon on MRNA
Purine (Adenine & Guanine) and pyramidine (Cytosine, Thymine, & Uracil) compounds found in DNA and RNA.
A sequence of three bases in mRNA that specifies a certain amino acid to be placed in a protein. A few codons signal the start and stop of transcription
The information in DNA that is transferred to mRNA as a sequence of codons for the synthesis of protein. Series of 3 nucleotides in mRNA called codons.
Produced in the nucleus by DNA to carry the genetic information to the ribosomes for the construction of a protein.
a change in the DNA base sequence that alters the formation of a protein in the cell.
large molecules composed of nucleotides found as a double helix in DNA and as the single strands of RNA
The combination of a pentose sugar and a base/
building blocks of a nucleic acid consisting of a base, a pentose sugar, and a phosphate group. formed when C5'-OH group of ribose or DNA in a nucleoside forms a phosphate ester.
The phosphate link that joins the 3'-hydroxyl group in one nucleotide to the phosphate group on the 5'-carbon atom in the next nucleotide
The sequence of nucleotides in nucleic acids
The process of duplicating DNA by pairing the bases on each parent strand with their complimentary base.
The most prevalent type of RNA and a major component of ribosomes.
A mutation that replaces one base in a DNA with a different base.
a virus taht contains RNA as its genetic material and systhesizes it as a complementary DNA strand inside a cell.
A physical malfomration or metabolic dysfunction caused by a mutation in the base sequence of DNA.
the transfer of genetic information from DNA by the formation of mRNA.
The interpretation of the codons in mRNA as amino acids in a peptide
An RNA that places a specific Amino acid into a peptide chain at the ribosome. There is one or more tRNA for each of the 20 different amino acids.
Small particles containing DNA or RNA in a protein coat that require a host cell for replication.
Unbranched polymers of repeating monomer units also known as nucleotides
DNA and RNA - 2 closely related nucleic acids.
Pyramidines w/an NH2
Is a Pyramidine w/a N3C
Is a pyramidine for RNA w/o a H3C
Is a Purine
Is a Purine w/ double bonded O
# of Condons possible from AGC&U
UGA, UAA, and UAG
if beginning then it can be the start and if in the middle then it can be methionine.
tRNA molecules, amino acids, and enzymes convert the codons on MRNA to make a protein.
