The following statements apply to concepts and material discussed in Chapter 6; identify which statement is TRUE.

Selected Answer:


Answers:

If a mother and son both have a homozygous dominant genotype, but only the mother suffers from symptoms associated with an X-linked condition, this is due to X Inactivation.

PAN syndrome is an X-linked condition. Women must inherit two faulty alleles to show symptoms, while men show symptoms when they inherit just one. This is an example of a Sex-influenced condition.


X chromosomes only contain genes that affect "sexual" traits related to "femaleness."

X-linked dominant conditions are more common than X-linked recessive conditions.

The following statements apply to concepts and material discussed in Chapter 9; identify which statement is TRUE.

Answers:

DNA consists of two nucleotide chains arranged in the same direction coiled into a helix.

DNA is directional, because one strand runs antiparallel to the other in a double helix.

DNA polymerase corrects every error that it makes during replication.

DNA replication has to happen before transcription and translation can.

DNA replication is considered a conservative process, because one parent strand is conserved and one new daughter strand is made.

Solutions

Expert Solution

Q1)

Answer a) False. X inactivation don't happen in males since they have only one X chromosome acquired from mother.

b)False. PAN syndrome is an autosomal recessive inheritance. It is not sex linked.

c)False. X chromosomes not only contain genes for female characters. It also contains important genes required for survival.

d)True. X linked dominant condition is commonly seen in females than males. But compared to recessive traits , they affect almost 50% of individuals from affected parents.

Q2)

a.False. the strands are in the opposite direction and antiparallel

b)True. DNA is directional and addition of nucleotides happen from 5' to 3'.

c)False. DNA polymerase corrects most of the errors. Some of them are missed. They lead to mutations.

d)False. DNA replication only needs to happen when cells divide.

e)True. DNA replication is conserved because the two strands each give rise to a daughter strand and therefore the parent strand is conserved.

The Snowplow Problem To apply the techniques discussed in this chapter to real-world problems, it is neces- sary to translate these problems into questions that can be answered mathematically. The process of reformulating a real-world problem as a mathematical one often requires making certain simplifying assumptions. To illustrate this, consider the following snow- plow problem: One morning it began to snow very hard and continued snowing steadily throughout the day. A snowplow set out at 9:00 am to clear a...
