5.3 Study Guide

Question 1

Similarities and Differences between DNA and RNA

Answer 1

RNA: ribose sugar, uracil instead of thymine, single stranded, many different types: mRNA,tRNA,rRNA,snRNA, is a smaller molecule
DNA: deoxyribose sugar, bases: A:T, G:C, double stranded, one type of DNA, large molecule
BOTH: made of a phosphate, sugar, and a base, both contain Adenine, Cytosine, and Guanine

Question 2

Eukaryotic gene is made up of…

Answer 2

prometer: start site for transcription , most eukaryotic prometers contain a TATA box:helps necessary proteins to attach
enhancer/silencer:additional binding site for transcription factors:proteins/RNA that can stop or start the transcription process
exons: sequences that will be present in the mRNA
introns: will be spliced out and removed
