Question

The frequency of recombination during is a function of: A) the alleles on the genes; recombination happens less frequently among recessive alleles. B) the distance between genes: the closer the genes are, the more frequent the recombination between them. C) the distance between genes: the farther apart the genes are, the more frequent the recombination between them. D) whether or not the genes are sex-linked; x chromosomes recombine much more frequently than do autosomes. E) whether or not the genes are sex-linked; Y chromosomes recombine much more frequently than do the autosomes. The four elements most common in all organisms are A) calcium, iron, hydrogen and oxygen. B) water, carbon, hydrogen and oxygen. C) carbon, oxygen, hydrogen and nitrogen. D) nitrogen, carbon, iron and hydrogen. E) phosphorus, water, carbon and oxygen. Genes that are located on the same chromosome and are close together. A) always segregate from one another during division. B) may not assort independently of each other. C) are always located on autosomes. D) are usually clustered on the Y chromosome. E) are never located on the X chromosome. Transcription is the process of A) DNA synthesis from RNA. B) RNA synthesis from DNA. C) protein synthesis from DNA. D) protein synthesis from RNA. E) DNA replication. According to the graph below, which complex trait shows very little influence from a genetic component? A) autism B) clinical depression C) schizophrenia D) bulemia nervosa E) female alcoholism Which of the following statements is false? A) Xist is active on the inactivated X chromosome. B) DNA methylation represses transcription. C) Histone acetylation increases transcription. D) The inactive X is a type of euchromatin. E) Epigenetic effects on gene expression do not involve changes to the DNA sequence.

Explanation / Answer

Ans - 22 - (C) the distance between genes : the farthest apart genes are the more fequencency among recessive alleles recombinatiuon between them.

increase in the distance results increase the frequency of segration and independent assort of the genes which results increse in the recombination frequency.

ans 23- (C) oxygen, nitrogen ,hydrogen and carbon. these are the major elements which build the building block of the body.

Ans 24- (b) not assort independently to each other. genes which are present on same chromosome and close to each other they are unable to assort independently to each other .generally they inheritent together

Ans25- (B) RNA synthesis from DNA , this process is known as transcription.in this process the DNA is trancript into mRNA
