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 |
