Direction: Multiple choice. Choose a correct letter as correct answer. No need to explain the answer. Thank you in advance. Zoom in the pictures in order to see it clearly. It's just two problem so please provide an answer in no. 1 and 2.
Which statement BEST DESCRIBES the tRNA structure? Chooose from the options below. Amino acids bind to the 5′ end of the tRNA molecule. When a tRNA has an amino acid attached to it, it is considered to be a charged tRNA Synthetases are not important to tRNA Amino acids are linked to tRNAs with hydrogen bonds

If the nucleotide at position 23 in the first strand of DNA is changed to "A", what effect would this have on the protein produced?
Match the descriptions to the molecules of transcription and translation. MRNA [ Choose ] v DNA [ Choose ] FRNA [ Choose ] TRNA [ Choose ]
TRANSCRIPTION The DNA provided for your animal is one side of the double helix. DNA - MRNA otein 1. Transcribe the DNA strand into mRNA. Don't forget the special base pair → rules for RNA! AU TA VERSION 1 2. Translate the mRNA into an amino acid chain. Notice that this is broken into 1 nucleotide sequences called CODONS. Use the codon chart to find the correct amino acids. Remember, translation for each chain always starts with the amino acid methionine (Met) and ends with one of the stop codons (UGA, UAG, UAA).

Match the proteins with their function in DNA replication. unwinds DNA at replication fork forms covalent phosphodiester bonds to join DNA fragments remove primer and replace the RNA with DNA, also has 3'-> 5'exonuclease activity for proofreading synthesizes DNA by adding to the 3' end of the growing strand of DNA adds RNA primer uses an RNA template to facilitate extension of the telomeres in eukaryotes introduces a double-stranded break ahead of the replication fork and swivels the cleaved ends around the central axis to relieve the stress of helix unwinding helicase [Choose ] ✓ helicase telomerase DNA polymerase II DNA polymerase I DNA polymerase III DNA primase DNA ligase D DNA Gyrase (topoiso- merase) exonuclease
Fill in the blanks of the sentence(s) below. The addition of amino acids to a growing polypeptide chain occurs by a new TRNA with amino acid moving into the site of the ribosome. a ribozyme breaks the growing polypeptide off the TRNA in the the ribosome and adds it to the amino acid on the tRNA in the site of site. The whole ribosome then moves Process continues until a stop codon is reached. Select one: a. P site, peptidyl transferase, A site, P site, one codon down (translocation) b. A site, peptidyl transferase, P site, A site, one codon down (translocation) C. A site, peptidyl transferase, P site, E site, three codon down (translocation) d. A site, amino acyl TRNA synthetase, P site, A site, one codon down (translocation)
Which is NOT a true difference between messenger RNA and DNA? (i.e., which of the following statements is false?) DNA remains in the nucleus (except when the nuclear envelope breaks down during mitosis), whereas mRNA is never in the nucleus; it is always in the cytoplasm. A DNA molecule has a longer life span than a typical molecule of RNA. DNA has thousands of genes; mRNA is usually a copy of just one gene. DNA has thousands of genes; mRNA is usually a copy of just one gene.
