What nitrogen bases are found in a DNA molecule and how do they differ from the bases found in the RNA molecule?

DNA: Adenine, Thymine, Guanine, Cytosine RNA: Adenine, Uracil, Guanine, Cytosine

The backbone of a DNA molecule is made up of what molecules The backbone of a DNA molecule is made up of what molecules? (Be specific in your answer.)

Deoxyribose Sugar and Phosphates

Where in the cell can RNA be found and how does that differ from the location of DNA?

RNA can be found in the nucleus, cytoplasm, and ribosomes RNA can be found in the nucleus, cytoplasm, and ribosomes. DNA is ONLY found in the nucleus.

What are Okazaki fragments?

The fragments of DNA added on the lagging strand during DNA replication

Transcribe the following DNA sequence: AATCGACCT

UUAGCUGGA

How many amino acids are coded for in the following: AUGUACCCATAG

AUG UAC CCA TAG 4

Transcription occurs in the _____ and translation occurs in the ______.

Transcription occurs in the NUCLEUS and translation occurs in the RIBOSOMES.

What type of mutation has occurred here: DNA: AACTAGAGG MUT: AACAGATGG

Inversion Mutation

What 2 types of mutations will cause a frame shift?

Deletion and Insertion

The start codon is AUG, what amino acid does this code for?

Methionine

WHAT are the 4 phases of the CELL CYCLE and what occurs during each phase?

G1 – growth, metabolism, protein synthesis S – DNA replication G2 – protein synthesis, metabolism, preparing for division M – Mitosis and Cytokinesis

If a liver cell contains 96 chromosomes, how many chromosomes does it contain after cell division?

96 – liver cells only divide through mitosis

If a zygote has 48 chromosomes, how many chromosomes in the gametes?

24

What are the two types of meiosis in humans that were discussed in class and what are their products?

Spermatogenesis – sperm Oogenesis – egg

What structure is responsible for lining chromosomes up in the middle of the cell and then pulling them apart?

Spindle Fibers

Give the genotypic ratio and phenotypic ratio for the following: Hh x Hh

GR – 1:2:1 PR – 3:1

If Black fur color (B) is dominant to white (b), what is the genotype for gray fur color and what type of inheritance is this?

Bb – Incomplete Dominance

A man with cystic fibrosis (XbY) and a homozygous non-cystic fibrosis woman (XBXB) have a son. Is it possible for that son to inherit cystic fibrosis? Why?

No, he will inherit the Y from the father and an XB from the mother

Colorblindness is a sex-linked recessive trait Colorblindness is a sex-linked recessive trait. How is it possible for 2 parents to have a daughter who is colorblind?

XbY and XBXb or XbY and XbXb The father must be colorblind and the mother must be either a carrier or colorblind. XbY and XBXb or XbY and XbXb

Give the probability of the genotype ffTt from the cross: FfTt x FFTt

There is a 0% chance that ffTt will be produced from FfTt x FFTt

What type of inheritance is shown below: Dominant, Recessive, or Sex-Linked

Recessive

Give the genotype of the person indicated below

Heterozygous

What is a pedigree?

A genetic family tree

Is it possible to determine traits such as eye color and hair color from a karyotype?

NO

What is non-disjunction and when can it occur?

Non-disjunction can occur during Anaphase I and Anaphase II and it is when homologous chromosomes or sister chromatids fail to separate from one another resulting in unequal #s of chromosomes/chromatids
