Mutations
Meiosis
100

The location of transcription within the cell

Nucleus

100

The site of protein synthesis. (like a protein-making "factory")

Ribosome

100
What is a mutation?

Random change to the DNA or RNA bases

100

Meiosis produces these kinds of cells

Gametes (sperm and egg)

200

Part of the DNA is copied to create this molecule

mRNA (messenger RNA)

200

This is what "translates" the mRNA bases and brings the correct amino acids

tRNA (Transfer RNA)

200

An environmental factor that can cause mutations

mutagen

200
If a cell starts out with 30 chromosomes before prophase I, how many will it have after telephase II?

15

300

This is the protein that "reads" and copies part of the DNA

RNA Polymerase

300

Every 3 bases of mRNA is called a...

Codon

300

This can be caused by adding or removing a base from a sequence, affecting all of the codons that follow the mutation.

Frameshift

300

What phase of meiosis is shown in the drawing?

Metaphase I

400

If DNA has the following bases, what bases will the complementary RNA have?

CGGTAGAT

GCCAUCUA

400

The two halves of a tRNA are the _____________ which matches with complementary mRNA bases and the __________________ which build a protein

anticodon, amino acid

400

Which of the 5 main categories of mutations is this?:

Original: TAC ACA CCT GCG

Mutatied: TAC CCT GCG ACA

Translocation

400
Make a drawing of cell in Anaphase I

See board

500

WHY does this step have to happen?

DNA can not leave the nucleus to get to the site of protein synthesis, so it has to create a "messenger"

500

Write the correct amino acid sequence for this strand of mRNA:

GCC AUG UUC CAG UAG AAC AUU

Met Phe Gln

500

Which type of substitution mutation is this an example of?

Original: AUG GGU UGC AAU GCA

Mutated: AUG GGU UGA AAU GCA

Nonsense

If the genes for hair color and eye color are on the same chromosome, can I pass on my dad's hair color, but my mom's eye color? WHY or why not?

Yes. Crossing over
