Flashcards do conjunto (15)
- 1What is DNA?Deoxyribonucleic Acid is a molecule found in all organisms and is found in the nucleus of each cell. It contains genetic material
- 2What are histones?Proteins which DNA strands are bound to
- 3What is chromatin?A tangled network made of coiled DNA
- 4What are chromosomes?One of the 46 rod-like structures that appear in the nucleus of a human cell during cell division
- 5What is a gene?A factor that determines a hereditary characteristic - part of a chromosome
- 6What is genetic code?The information stored in DNA molecules
- 7What are the four DNA bases called?1. Adenine
2. Thymine
3. Guanine
4. Cytosine - 8Which bases pair with each other?Adenine & Thymine
Guanine & Cytosine - 9What is DNA replication?When DNA forms exact replicas of themselves
- 10What is transcription?The process by which mRNA is formed using the code in a DNA molecule. Genetic instructions are copied from DNA to mRNA moluecule.
RNA have base Uracil (U) instead of Thymine - 11What is translation?The production of protein using the information that is coded in the mRNA molecule

- 13What is messenger RNA (mRNA)?RNA molecule that carries the code for protein synthesis from the DNA in the nucleus to the ribosomes where the protein is made
- 14What is transfer RNA (tRNA)?A small RNA molecule that transfers the correct amino acid to the ribosome for inclusion in the protein molecule being made
- 15What are epigenetics?Altering expression of a gene without changing the gene structure
