|---|---|
| What is the process name for when DNA makes a copy of itself? | Replication |
| If mutations occur in this type of cell, it can be passed on to offspring? | gametes |
| What type of bond attaches the amino acids together to form a protein? | peptide bond |
| What type of bond holds the bases together in the DNA double helix? | hydrogen bonds |
| What is the enzyme used during transcription that will unwind DNA and add nucleotides to create a mRNA strand? | RNA polymerase |
| What is the process name for when the mRNA strand is used to make a protein? | Translation |
| What type of mutation has DNA bases switching places? | Inversions |
| What is the enzyme that unwinds the DNA during replication? | DNA helicase |
| What are the 3 parts of a nucleotide? | sugar, phosphate, base |
| If an original DNA is represented as: 12345 And the mutated one is represented as: 126345 What type of mutation is this? | Addition |
| What base is not in RNA but is in DNA? | thymine |
| What are the 3 bases on a tRNA strand called? | anticodon |
| Franklin’s photo and experiments showed that DNA was a __________ ________________. | double helix |
| After transcription the mRNA leaves the ______ and goes to the __________. | nucleus, ribosome |
| Are all mutations harmful? | no, some have no change, some are beneficial |
| What is the enzyme that will put strands together during replication? | DNA ligase |
| This type of category of mutations are when the multiples of 3 (codons) change. | Frameshift mutation |
| What type of RNA molecule has an amino acid attached and carries them to the ribosome? | tRNA |
| What would be the mRNA strand for the following DNA strand: G T T A C C T A | C A A U G G A U |
| If mutations occur in this type of cell, it cannot be passed on to offspring? | somatic (body cells) |
| If the codon is this: CAG what is the anticodon? | GUC |
| In what phase does replication take place? | S phase (in interphase) |
| What are the 3 bases called on a mRNA strand? | codon |
| What is the enzyme that will add nucleotides and proofreads during replication? | DNA polymerase |
| What is the process name for making mRNA from a DNA gene? | transcription |
| This type of category of mutations are based upon a single base pair change. | Point mutations |
| What are the sugars in DNA and in RNA? | deoxyribose=DNA, ribose=RNA |
| What is the general term for environmental factors that can cause mutations (like pesticides) | mutagens |
| The mRNA will be read by each codon until it reaches a ___________ signal. | stop |
| What is the other side of the DNA if this is one side: T T C A G A T G | A A G T C T A C |
| What type of mutation has DNA from one chromosome moving to another chromosome? | Translocation |
| What is a general term for a change in the DNA code? | mutation |
