Using the alleles R and r, what does homozygous recessive mean?

rr

Where does transcription take place in the cell?

nucleus

What is a mutagen?

something that causes mutations

100

In what part of the cell is DNA duplicated?

the nucleus

200

What is it called when the cell pinches and divides?

cytokinesis

If someone has a 3:1 chance of expressing the dominant trait, what percent is that?

75%

What are the major differences between RNA and DNA?

double/single stranded

deoxyribose/ribose

thymine/uracil

List 3 examples of environmental mutagens.

cigarette smoke, x-rays, nuclear waste, pollution, sun damage

200

What does RNA polymerase do?

makes a mRNA copy

300
At what stage do chromosomes line up at center of the cell?

metaphase

Cross a heterozygous tall pea plant (Tt) with a homozygous short peaplant (tt). What is the resulting breakdown of potential PHENOTYPES?

Tt x tt = Tt, tt, Tt, and tt

2 Tt = 2 Tall

2 tt = 2 short

300

where does translation occur in the cell?

ribosome

Answers will vary

How many chromosomes do human haploid cells have?

23

400

during what stage does recombination or crossing over occur during meiosis?

prophase I

If someone's child has a 25% of being hh, draw the whole Punnett square, including the genotypes of their parents

Parent 1: Hh

Parent 2: Hh

HH, Hh, Hh, hh

describe the steps of translation.

mRNA arrives in the ribosome, tRNA brings the anticodon and amino acid and matches it to the codon, a chain of amino acids is maid to make a protein
400

What are the stages of cell division (mitosis)?

Interphase

Prophase

Metaphase

Anaphase

Telophase

Cytokinesis

400

What is another name for body cells?

somatic

500

Human body cells contain 46 chromosomes. Are these haploid or diploid cells?

diploid

500

Why is the population of redheads decreasing?

The trait for red-headedness is recessive, meaning the child needs to receive two recessive alleles to express the trait. It is over-ridden by the dominant allele. As red-headed people mix with the rest of the population, that allele expression is decreasing.

500

describe the steps of transcription. include names of enzymes involved.

DNA is in the nucleus, helicase unzips the DNA, RNA polymerase make the mRNA copy one nucleotide at a time, mRNA then leaves the nucleus to go to the ribosome
500

What are 3 different types of Mutations?

insertion, deletion, substitution

500

helicase, RNA polymerase, amylase, ligase, sucrase, primase
