dna Through Geneitc Engineering Flashcards
Which type of gene is readily taken from one location and inserted into another location of the same DNA?
transposon
What is the best reason for organisms to use mitosis?
To produce two genetically identical diploid cells
Describe three major steps that occur as a DNA molecule is copied during replication.
1) separation of 2 DNA strands
2) makes new complementary strand
3) nucleotides connects to form sugar back bone.
During which process does Mendel’s Law of Segregation apply?
Meiosis
What name is given to the changes in DNA that can affect the transfer of genetic information from parent to offspring?
Germ mutation
In which type of animal cell will a mutation most likely be passed on to their offspring?
Sex cells
Which is the best method to help parents identify the probability of passing on a genetic disorder to their offspring?
Pedigree
The curled ears of the American Curl cat are caused by an autosomal dominate allele. What are are the changes of a heterozygous female and a curled eat male producing offspring with curled ears?
3/4
What is the source of genes during sexual reproduction?
Gametes
Which type of gene mutation affects no more than just a single amino acid during protein synthesis?
Substitution
Genes are located on…..
Chromosomes
Which letter represents a corrects base pair of DNA?
Adenine - Thymine
If an individual with a genotype of AO is crossed with a genotype of AB, The offspring have…..
1/2 a chance of having type A blood
Which human blood donor is capable of sharing their blood with almost anyone?
Blood type O
In some breeds of rabbits a dominate allele controls the trait of long ears. If a breeder mates a homozygous long-eared rabbits with a heterozygous long-eared rabbit, what ration of the offspring will have short ears?
0/4
During Mendel’s experimentation with lea plants, he crossed a plant that had round peas with a plant that round peas. Three of the four offspring had round peas. One produces wrinkled peas. What is true about the genotype of the parent plants?
One parent had a genotype of Rr, the other parent had he phenotype Rr
Not true statement concerning the similarity of DNA between two humans?
The DNA of two individuals is exactly identical even if they are not identical twins
South American parents can be pink. It is generated from incomplete dominance of a gene the normally produces red. When white and red mate they produce pink.
RRxWW
100% of the offspring would be pink
Animal cell to nucleus to chromosome to DNA to:
Gene
Interpret the dihybrid cross. What is the probability of getting a round and green seed R-round R-wrinkled Y- yellow y-green
3/16
RRyy
Rryy
Which three compounds represent the structure of a typical nucleotide?
Deoxyribose, Adenine, and a phosphate group
Cells assemble proteins to conduct the activities and communicate with other cells through which process?
Translation
Skin cancer is an example of?
Somatic mutation.
What is the potential advantage for And organism whose genes cross over during meiosis?
The new combination of alleged give the organism a natural Immunity to certain viruses
The new combination of alleles may give the organism traits that enable the organism to survive in an environment more effectively than other organisms.
Mutation in animals gametes could result in:
An animal being unable to reproduce
The offspring Inheriting new traits not seen in the parent
The offspring inheriting new traits to decrease their chance of survival in the environment.
Male pattern baldness is an example of a:
Sex linked trait
Which statement correctly describes the roles of DNA and genes?
To control activity of the cell through synthesis of proteins
To pass on an organism characteristics from parent to offspring.
A molecule that carries genetic information form one Nucleus to ares that synthesize protein is:
Messenger RNA
Of a gene for the making of a specific protein in a mammal is inserted into a bacterium, how would the bacterium be effected?
Would begin producing the specific mammal protein.
