DNA Structure & Uses
This is the shape of DNA.
What is a double helix?
What are 2 differences between DNA and RNA?
What are:
size, T vs. U, sugar
This process turns DNA into RNA
What is transcription?
These make up the backbone of DNA.
What are sugars (deoxyribose) and phosphates.
This is the first step in the replication of one DNA molecule AND transcription.
What is the unwinding or unzipping of DNA?
These molecules transport amino acids to ribosomes
What is transfer RNA (tRNA)?
What are 2 environmental factors that can have an influence on gene expression?
What is ...
sunlight, heat, diet, pollution, stress, etc
These are the base-pair rules for DNA
A-T
C-G
These make up a nucleotide
What are (nitrogenous) base, a sugar, and a phosphate.
This process turns RNA into proteins
What is translation?
This is where translation takes place.
What is the ribosome?
What is the molecule called that cuts up DNA?
What is a restriction enzyme?
Why does transcription happen in the nucleus?
What is the definition of protein that we have been using in class?
What is a chain of amino acids
Put the following terms in the order that they happen: DNA, RNA, protein synthesized, translation, transcription
What is DNA --> transcription --> RNA --> translation --> protein synthesized
What is a technique used to change DNA?
What is genetic engineering?
Order these from smallest to largest: gene, cell, chromosome, nucleus
What is gene, chromosome, nucleus, cell
This is the first step in the replication of one DNA molecule AND transcription.
What is the unwinding or unzipping of DNA?
What protein carries oxygen in our blood?
What is hemoglobin
Give 2 examples of what can cause a mutation.
What is radiation, chemicals (like nicotine), an error in DNA replication
