• DNA

• RNA

Poll

The genetic material found in all living things.

• DNA

• RNA

Fill in the Blank

In the nucleus of eukaryotic cells, _______ wraps around histones to form chromatin which makes up chromosomes.

Multiple Choice

Chromosomes contain tens of thousands of ____________ (unit of heredity passed from parent to offspring)

• Nucleus

• Genes

• Carbohydrates

• Protein

Poll

All the _________ necessary for life in a eukaryotic organism is found in every somatic cell that makes up that

organism. Genes are turned “on or off” depending on the location of the cell.

• DNA

• RNA

• Carbohydrates

• Fats

Poll

_______ is involved in protein synthesis.

• DNA

• RNA

Multiple Choice

______ molecules never leave the nucleus.

• DNA

• RNA

• H2O

• mRNA

Multiple Choice

________________ is the single strand of transcribed DNA that leaves the nucleus and is used to code for

protein production.

• DNA

• Carbohydrates

• mRNA(Messenger RNA)

• Proteins

Poll

DNA and RNA are made up of three components: nitrogenous base, a sugar, and a _______________

• Protein

• Phosphate

• Carbohydrate

DNA/RNA

Each base is attached to a sugar which is then attached to a phosphate group.

Organic or Not?

Nitrogenous bases are organic because they contain carbon and nitrogen

Poll

Base pairing for _____ is A-U, C-G

• DNA

• RNA

Multiple Select

DNA strands are:

• Round in Shape

• complementary to one another.

• Randomly assorted

• Run in opposite directions

Multiple Select

There are 4 types of RNA:

• messenger RNA (mRNA)

• transfer RNA (tRNA)

• microRNA (miRNA)

• DNA

• ribosomal RNA (rRNA),

Multiple Choice

________ carries messages from DNA

• tRNA

• rRNA

• mRNA

Transcription and Translation

• When a protein is needed the mRNA is copied from the DNA strand and send out of the nucleus to the ribosomes.

• The mRNA is read in sets of three bases called codons.

• Each codon codes for an amino acid.

What does RNA do?

rRNA ensures the mRNA is aligned properly in the ribosome.

What does RNA do?

tRNA carries the correct amino acid to the site of protein synthesis

What does RNA do?

miRNA regulate gene expression by interfering with mRNA messages.

Transcription/Translation Overview

• Information flow is DNA-RNA-Protein

• DNA to DNA is Replication

• DNA to mRNA is transcription

• mRNA to amino acid is translation
