This diagram is a picture of Translation Referring to the diagram in number 1: -letter A is the ribosome -letter B points to a codon -letter C points to an anticodon -letter D points to a polypeptide chain -letter E points to an amino acid -letter F points to an tRNA -letter G points to an mRNA DNA and RNA are Nucleic Acids. The sequence of nucleotides in a messenger RNA molecule is determined by the sequence of nucleotides in a DNA molecule. Which of the following is the smallest structure? nucleotide • DNA • nucleotide(correct answer) • nucleus • chromosome • transport amino acids to mRNA (correct answer) The function of tRNA molecules is to: An mRNA sequence reads UACAGUGCUAGA. The DNA sequence that this mRNA was made from is: ATGTCACGATCT Use the figure below to answer question 14-18. This is the genetic code using mRNA codons. ! What mRNA codon is the "start" codon? AUG The mRNA codon CAC codes for which amino acid? histidine Which 3 amino acids are coded for by the DNA strand ATGGCTATA? (list the amino acids in order, seperated by commas, and spelled correctly!) Tyrosine, Arginine, Tyrosine Which amino acid is "transferred" by a tRNA with the anticodon CUA? aspartate Which DNA sequence could code for the polypeptide chain; Serine - Alanine - Glycine - Proline? AGTCGGCCAGGT RNA has only one strand, is directly involved with translation, Exists in 3 different forms, can be attached to a ribosome, Both DNA and RNA contains Adenine, Pentose Sugar, are made from nucleotides, can be found in the nucleus, DNA contains Thymine, With the help of enzymes, it is able to replicate itself The backbone of a DNA molecule is made of Deoxyribose and Phosphate Ribose and deoxyribose are both examples of sugars A phosphate, nitrogen base, and a sugar make up subunits of nucleic acids also called nucleotides. DNA Replication occurs in the nucleus A triplet of 3 bases found on mRNA which code for an amino acid is called a codon Purines are nitrogen bases with 2 rings while pyrimidines have 1 ring. Which two bases are purines? Adenine and Guanine The "rungs" of the DNA molecule are composed of nitrogen base pairs. This bases are joined together by Hydrogen bonds. Protein synthesis can be summarized as: DNA is Transcribed to mRNA. mRNA is Translated to protein. The picture below is a Nucleotide The yellow structure is a nitrogen base The purple structure is a sugar The orange structure is a phosphate group
