|---|---|---|---|---|---|
| What are nucleic acids? | show 🗑
|
||||
| show | Nucleotides
🗑
|
||||
| show | Adenine (A), guanine (G), thymine (T), and cytosine (C).
🗑
|
||||
| What are the complimentary DNA nucleotide bases? | show 🗑
|
||||
| What are the four RNA nucleotides? | show 🗑
|
||||
| show | Guanine and Cytosine. Adenine and Uracil.
🗑
|
||||
| show | Scientists label the carbons in the sugar from 1' to 5' based on their position in the molecule. The phosphate group is attached to the sugar at the 5' carbon
🗑
|
||||
| True or False: One sugar-phosphate chain runs in the 5' to 3' direction and the other runs in the 3' to 5' direction. | show 🗑
|
||||
| show | Hydrogen bonds
🗑
|
||||
| What shape does DNA take? | show 🗑
|
||||
| What shape does RNA take? | show 🗑
|
||||
| What charge is the DNA phosphate in the backbone? | show 🗑
|
||||
| True or False: DNA is not a polar molecule, so it cannot be easily dissolved in water, but dissolves in non-polar solvents such as alcohol. | show 🗑
|
||||
| show | In eukaryotic organisms, DNA is contained inside the cell nucleus. DNA is tightly coiled around proteins to form structures called chromosomes.
🗑
|
||||
| show | The result of coding information determined by DNA
🗑
|
||||
| show | The DNA of prokaryotes is usually arranged in a single circular chromosome that is located in an area called the nucleoid and may be loosely tethered to the cell membrane.
🗑
|
||||
| True or false: Chromosome number does not directly relate to the complexity of organisms. | show 🗑
|
||||
| Where is genetic information located? | show 🗑
|
||||
| show | Genes. Each gene codes for a different protein. An organism’s DNA contains the genes to code for all of the proteins that the organism needs to produce structures and carry out life processes.
🗑
|
||||
| True or False: Genes are made up of sequences with three-base segments called codons. | show 🗑
|
||||
| True or False: Different codons code for unique amino acids. Some amino acids may not be coded for by more than one codon. | show 🗑
|
||||
| How many different amino acids are there? | show 🗑
|
||||
| show | True
🗑
|
||||
| show | The process of synthesizing RNA from a DNA template. The cell copies the information in a gene by making complementary messenger RNA strands
🗑
|
||||
| Explain translation. | show 🗑
|
||||
| During transcription, the enzyme RNA polymerase catalyzes the copying of base codes in a gene from DNA to a complementary strand of mRNA. Where does this strand go? | show 🗑
|
||||
| Ribosomes are made of another kind of RNA called ribosomal RNA (rRNA). What occurs here? | show 🗑
|
||||
| show | tRNA, carries amino acids to the ribosomes and attaches them in the order coded on the mRNA molecule.
🗑
|
||||
| How are amino acids linked together? | show 🗑
|
||||
| When does DNA replication begin? | show 🗑
|
||||
| show | True.
🗑
|
||||
| show | The leading strand. Synthesis of the other strand—the lagging strand—occurs in segments.
🗑
|
||||
| What are the names of each DNA strand during replication? | show 🗑
|
||||
| show | A genetic copy.
🗑
|
||||
| show | Amino Acids
🗑
|
||||
| What determines the genetic code of a region of DNA? | show 🗑
|
||||
| show | Double-stranded helix
🗑
|
||||
| show | Tightly wound DNA and proteins
🗑
|
||||
| show | Chromosomes.
🗑
|
||||
| show | A sugar phosphate group and thymine.
🗑
|
||||
| show | Helicase
🗑
|
||||
| Which of the following is NOT a type of RNA? Ribosomal, messenger, translational, transfer | show 🗑
|
||||
| Messenger RNA delivers a "message" from ________ to ________. | show 🗑
|
||||
| show | Protein
🗑
|
||||
| show | 4 possible nitrogenous bases.
🗑
|
||||
| How are the four DNA bases typically abbreviated? | show 🗑
