Biology 5th ch 18,19
| Question | Answer |
|---|---|
| Nucleic acid | |
| Nucleotide | |
| DNA bases | |
| Base pairs | |
| Purine | |
| Pyrimdines | |
| What are the RNA bases | Adenine, uracil, cytosine, guanine |
| What are the DNA bases | Adenine, thymine, cytosine, guanine |
| Differences between DNA and RNA | DNA • Double strand • Sugar is deoxyribose • Has Thymine base • Found only in the nucleus RNA • Single strand • Sugar is ribose • Has Uracil base •Found in nucleus and cytoplasm. |
| Characteristics | |
| Traits | |
| Chromosomes | |
| Histones | |
| Coding DNA | |
| Non Coding DNA | |
| Gene | |
| Locus | |
| Gamete | |
| Fertilisation | |
| Nuclear inheritance | |
| Non - nuclear inheritance | |
| A long chain of nucleotides that stores and carries genetic information. | |
| A unit of DNA or RNA made up of a nitrogenous base, a sugar and a phosphate. | |
| A-T and C-G | |
| A nitrogenous base that has a double ring structure (adenine and guanine). | |
| A nitrogenous base that has a single ring structure (thymine and cytosine). | |
| Describe physical genetics | |
| A form of characteristic | |
| A condensed, thread-like structure made up of DNA and proteins. | |
| The protein in chromosomes that binds to DNA and helps it to coil up. | |
| DNA that carries instructions for building proteins. | |
| DNA that does not carry instructions for building proteins but has other functions. | |
| A small section of DNA that contains the code for protein | |
| the specific, fixed physical location of a gene or DNA sequence on a chromosome | |
| A sex cell that contains half the full set of chromosomes. In humans, the female gamete is the egg and the male gamete is the sperm. | |
| The fusion of the nuclei of the egg and the sperm to form a zygote. | |
| Nuclear inheritance involves a huge number of genes and controls most of an organism's traits. The mix of both parents' DNA increases genetic diversity in the next generation. | |
| Non-nuclear inheritance is the inheritance of traits from the DNA in organelles outside of the nucleus. Compared to the 20,000+ genes passed on by nuclear inheritance, only a small number of genes are inherited as a result of non-nuclear inheritance. | |
| Genetic code | The set of instructions in the cells of all living things for turning the information in sequences of DNA bases into proteins. |
| A nucleotide diagram | 1/12/25 |
| What sugar does DNA and RNA have | DNA sugar is deoxyribose and RNA sugar is ribose |
| Where is DNA found | Only in the nucleus |
| Where is RNA found | In the nucleus and cytoplasm |
| Triplet | A sequence of three DNA bases |
