Mitosis results in the formation of:
diploid somatic cells
haploid gametes
haploid somatic cells
diploid gametes
diploid somatic cells
What type of pentose sugar is found in RNA?
uracil
ribose
deoxyribose
ribosylated nucleic acid
ribose
DNA carries our genes which determine how we:
,function develop
behave
all of the above
all of the above
Nondisjunction refers to when:
enzymes are unable to let go of the DNA and/or can cause point mutations
the replication of proteins is stopped by a stop codon
the chromosomes fail to separate properly during meiosis
polar bodies formed during meiosis failure of chromosomes to separate properly during
meiosis
one base pair change in any DNA sequence is known as:
single nucleotide polymorphism
anuploidy
somatic mosaicism
Phenylketonuria
single nucleotide polymorphism
Haemophilia is a form of which genetic disorder?
sex-linked dominant
, autosomal dominant
sex-linked recessive
autosomal recessive
sex-linked recessive
Use a Punnett square to determine the expected proportion of offspring that express the
dominant phenotype given the parents are Bb and bb genotypes. B = dominant allele, b
= recessive allele. The proportion that express the dominant phenotype would be:
1/2
1/4
3/4
all of the offspring
1/2
Use a Punnett square to determine the expected proportion of offspring that are
heterozygous given the parents are BB and bb genotypes. B = dominant allele, b =
recessive allele. The proportion that are heterozygous would be:
3/4
1/4
1/2
all of the children
all of the children
