Vocabulary Terminology for Chapter 11 in Friendly Biology
| Question or Term | Answer or Definition |
|---|---|
| The making of a protein is | protein synthesis |
| 1st step in protein synthesis is | the unzipping of the desired DNA by enzymes |
| the instructions or "recipe" for making proteins is found in | DNA or genes |
| DNA segment used for creating proteins is found in what part of the cell | Nucleus |
| The four nitrogen bases found in DNA are | Adenine, Thymine, Cytosine, Guanine |
| What determines the type of protein synthesized | the sequence of the bases |
| What unzips or opens the DNA for protein creation | enzymes |
| Once the DNA is unzipped by enzymes what is exposed | base pairs |
| What can be formed to make a copy of the sequence of of the exposed base pairs | RNA |
| RNA stands for | ribonucleic acid |
| Unlike DNA, RNA doesn't have the base Thymine, it has | Uracil |
| How many strands does RNA have | one or single |
| When RNA molecules align with exposed DNA bases, the RNA base Uracil bonds with | Adenine |
| The RNA that forms on the DNA bases takes on the name | mRNA or messenger RNA |
| The formation of mRNA takes place in nucleus of the cell whereas protein synthesis takes place in what part of the cell | cytoplasm |
| proteins get built or assembled in what part of the cell | ribosomes, which are found on the rough ER or endoplasmic reticulum |
| The mRNA strand codes for specific amino acids because it can be divided into three-base segments known as | Codons |
| At the ribosome, amino acids available are "tagged" with | tRNA or transfer RNA |
| The available amino acids when they ready to be assembled into proteins have segments of tRNA attached and they align themselves with segments of | mRNA |
| The tRNA is specific for each amino acid and acts like a | key |
| The tRNA will only fit the appropriate sequence of mRNA and mRNA acts like a | lock |
| The tRNA is in sets of how many base pairs | 3 |
| These 3 based pairs in tRNA is called | anticodon |
| Transcription is | The process in which information is communicated from DNA to mRNA within the nucleus |
| Translation is | The process in which information is communicated from mRNA to the ribosomes |
| Amino acids align to mRNA and form what kind of bond | peptide |
| What causes the peptide bond to form between amino acids and mRNA | enzymes |
| When DNA is damaged or altered, then the proteins made from this DNA may | NOT work or function correctly |
| Damaged or altered DNA is known as | genetic mutation |
| Causes of mutations are called | mutagens or teratogens |
| Radiation or energy from the sun is an example of what | mutagen |
| cells that change their behavior due to altered DNA may become | cancer cells |
| Cancer cells are treated with radiation in an attempt to cause | mutations in the DNA leading to their destruction |
