| Question | Answer |
|---|---|
| Molecule used as blueprint for all life | DNA |
| Full name of DNA | deoxyribonucleic acid |
| What are the three parts to a nucleotide? | phosphate, sugar, base |
| What is the sugar found in DNA? | deoxyribose |
| What are the 4 nitrogen bases found in DNA? | Adenine (A), Guanine (G), Thymine (T), Cytosine (C) |
| What are the base pairing rules for DNA? | A-T, G-C |
| What makes up the backbone of a DNA molecule? | phosphate and sugar |
| What makes up the rungs of the DNA ladder? | nitrogen bases |
| What kind of bond holds together the nitrogen bases in DNA? | weak hydrogen bonds |
| Where in the cell is DNA found? | nucleus |
| What are the two types of nucleic acids? | DNA and RNA |
| What does RNA stand for? | Ribonucleic Acid |
| What type of sugar is found in RNA? | ribose |
| How many strands are found in a RNA molecule? | 1 |
| What are the two differences between a DNA nucleotide and a RNA nucleotide? | the sugar: DNA has dooxyribose and RNA has ribose. the bases:DNA has A, T, G, C and RNA has A, U, G, C |
| What are the four nitrogen bases in RNA? | Adenine (A), Uracil (U), Guanine (G), Cytosine (C) |
| What are the two parts of Protein Synthesis? | Transcription and Translation |
| What is the first part of Protein Synthesis? | Transcription |
| Where does transcription take place in the cell? | nucleus |
| What is used during transcription to make mRNA? | DNA |
| What does the "m" in mRNA stand for? | messenger |
| What serves as the template for making mRNA? | DNA, since mRNA is made in the nucleus during transcription from DNA |
| How many strands is mRNA? | one, like all RNA molecules |
| What is a codon? | 3 bases in a row |
| What two molecules have codons? | DNA and mRNA |
| What would the mRNA codon be if the DNA template is ATG? | UAC |
| Where does the mRNA take the message after transcription is over? | to the cytoplasm to a ribosome for translation |
| What is the second part of Protein Synthesis? | Translation |
| What is being "translated" during translation | the mRNA to make proteins |
| What does the mRNA insert into to start translation? | a ribosome |
| After mRNA inserts into a ribosome, what molecule begins to bind to mRNA? | tRNA with amino acids attached |
| What is attached to the end of each tRNA molecule? | a specific amino acid? |
| How many bases in an anticodon? | 3 |
| What molecules has anti-codons? | tRNA |
| What does the "t" stand for in tRNA? | transfer |
| What does tRNA transfer the message from? | mRNA |
| Where did mRNA get the message from to start translation? | DNA during transcription |
| After tRNA anti-codons attach to mRNA codons in a ribosome, what happens next? | The amino acids on the ends of the tRNA molecules bond together to form proteins. |
| What are proteins made of? | amino acids |
| How many difference amino acids are there? | 20 |
| Where are proteins made? | at a ribosome during translation |
| What four nitrogen bases are there in tRNA? | same as all RNA: A, U, G, C |
| How many codons in the DNA strand: ATGCGTTCA | 3: ATG-CGT-TCA |
| What is the tRNA complimentary bases if the mRNA codon is UGC? | ACG |
| What molecule is used to find the amino acids on a codon chart? | Always use mRNA when using a codon chart |
| What two molecules are used in transcription? | DNA and mRNA |
| What is the order of translation? | mRNA --> tRNA with amino acid attached --> protein |
| What molecule is used in both transcription and translation? | mRNA |
| What two places does protein synthesis occur? | nucleus for transcription and in the cytoplasm at a ribosome for translation |
| What is the only molecule that has anti codons? | tRNA |
| What do you HAVE TO use to find the amino acids on a codon chart? | mRNA |
