Mutations and Genetic Change
... 4. If a mutation causes a sequence of nucleotides to change from ACGAGA to
ACGAGGA, the mutation is called a(n) [insertion / deletion] mutation.
5. Mutations that change one or just a few nucleotides in a gene on a
chromosome are called [random / point] mutations.
6. If a point mutation is such that ...

Schindler Disease - Great Ormond Street Hospital Laboratory
... disease, which is caused by a deficiency of the enzyme, alpha-Nacetylgalactosaminidase (NAGA). NAGA is a lysosomal glycohydrolase that cleaves
alpha-N-acetylgalactosaminidase moieties from glycoconjugates inside lysosomes.
Schindler disease is clinically heterogeneous with 3 main phenotypes; type 1 ...
Mutations - ScienceGeek.net Homepage
... – Mutations that occur in germ cells (sperm,
eggs) are passed on to offspring
– Mutations in somatic (body) cells may be
harmless, or may result in disease such as
... Chromosomal Mutations
• Nondisjunction = failure of
homologous chromosomes to
separate during meiosis resulting
in gametes (egg or sperm) with too
few or too many chromosomes
Mutation Study Guide

Point mutation/substitution and frameshift mutation
4. List two types of chromosomal mutations
Gene duplication and translocation

Genotype Analysis Identifies the Cause of the “Royal Disease”
... as a control for potential contamination and
unambiguous identification of the sample (4).
We found no evidence for nonsynonymous missense or small insertion-deletion mutations in either
F8 or F9 genes in the specimens. However, we detected an A-to-G intronic mutation located three
base pairs upstre ...
... a. What type of mutation is this? (substitution, insertion, or deletion?)
b. Would it be considered a frameshift mutation? Why or why not?
c. Rewrite the amino acid sequence with the mutated strand.
d. Is this considered a “silent” mutation (a mutation that causes no changes) or is it an
Variation and Selection
... • Variation in a limited number of phenotypes
with no intermediates.
• Example: various human blood type
different color of flower
Give an account of gene mutation under the following
... sequence/base order (nucleotide can be taken to be equivalent to
7. Substitution: base/bases are replaced with another/others
8. Inversion: order of bases reversed/bases turned around
9. Substitution/inversion may change base order of codon OR
substitution/inversion is a point mutation

1. What is a mutation? _________________________________________________________________
Part A. Transcription and Translation
Consider the following strand of DNA:
... Define and illustrate a Point Mutation.
Define and illustrate a Frame shift Mutation.
Why do you think that an excess of genetic material is usually less harmful
to an organism than a deficit.
Mutations in Paternity
... Unlike the RFLP case, the formula will depend on the actual alleles and
possible patterns of sharing. Instead of trying to give a general treatise, I'll just
illustrate with one typical example.
Suppose the mother is PP, the child is PQ, and the man is Q'R, where Q' is s=l
or 2 steps smaller (or lar ...
... In the following assignment you will characterize a mutation that is associated with a deficiency in the
human immune system’s response to bacterial infection. In this hypothetical situation, a patient has
an unexplained immune deficiency that causes them to be susceptible to typhoid fever (Salmonel ...
Please word process your answers.

In human genetics, Haplogroup G-P303 (P303) is a Y-chromosome haplogroup. It is a branch of haplogroup G (Y-DNA) (M201). In descending order, G-P303 is additionally a branch of G2 (P287), G2a (P15), G2a3 (L30 or S126) and finally G2a3b (L141). This haplogroup represents the majority of haplogroup G men in most areas of Europe west of Russia and the Black Sea. To the east, G2a3b1-except in the Caucasus Mountains area-is just a large or small minority among G persons in such locales as Turkey, the Middle East, Iran, the southern Caucasus area, China and India.
