DNA Replication, Transcription, and Translation Quiz



DNA Replication, Transcription, and Translation Quiz

__1__ and __2__ were the first scientists to create a model of DNA. Deoxyribonucleic acid is made of the sugar deoxyribose, phosphates, and __3___.

In DNA replication, the DNA unzips and free __3__ match up with each single strand. __4__ bonds to Thymine (T) and Cytosine (C) bonds to __5__ to form two identical strands of ___6___.

In protein synthesis, the __7__ makes a single stranded copy of the DNA in the __8__ which is a large organelle found in the center of most cells. The __7__ then leaves the __8__ and travels to the __9__ which is an organelle that makes proteins. Translation begins when the nucleotide sequence (order) is AUG on a __10__.

__11__ brings nucleotides to the __7__, bound in groups of three called __12__. The __13__ on the __7__ are matched up with __12__ from __11__. Once the __7__ has been read the __14__ ends protein synthesis.

In RNA strands Adenine (A) bonds to __15__ and Cytosine (C) bonds to __5__.
