Codominance when more than two alternatives for a gene exist 4.

. B Mutations in the DNA are a primary source of variation in prokaryote populations. Changing one nucleotide is a mutation but duplication of an entire gene is not A deletion mutation in a coding gene will always result in the change of the corresponding amino acid sequence. Mutations can result from spontaneous events or external mutagens.

B Cancer can only occur with a mutation in a germ cell. All cells from a single organism express the same genes. In this problem we will be working on mutations.

Cancer is a disease which causes abnormal cell growth with the potential to invade or spread to other parts of the body. Orthologous genes are genes from different species that have been selected in the same. Which of the following statements regarding mutation rates is correct.

SnRNPs at a 5 splice site can recognize and bind to snRNPs at another 5 splice stie. Mutations can be described as any changes in the sequence of the DNA. A all mutations cause evolution b any change to the dna of an organism is called evolution c all mutations are harmful d evolution happens slowly over time.

Hence option C best describes the mutations. Mutations can occur in both somatic and germ cells. Mutation rates are independent of exposure to external agents such as UV radiation.

Mutation rates for all genes of an organism are approximately the same. All of the above. Replication separation of DNAs two polynucleotide chains which act as a template for a new chain 2.

Mutations in a non-splice site for example middle of an intron does not affect the protein. Which of the following statements about mutations is false. Mutation rates are independent of gene size.

Mutations are alterations in normal DNA sequence. Mutations can happen spontaneously without any outside influence. Ultraviolet rays are a strongly ionizing radiation Which of.

Which of the following statements about the mechanism of splicing is correct. Genetics can be defined as the scientific study of hereditary and its components genes chromosomes etc within the body of an organism such as an animal human and plant. Correct option is A Mutations are the random changes in genetic material of organisms leading to genetic diversity.

B A mutation is any change in an organisms DNA. Mutation when both genes are dominant and both are expressed in the phenotype 3. D The origin of genetic variation is.

A Silent mutations are changes in DNA sequence that alter the amino acid and they do not change the biological function of the altered sequence. The statement that is correct is C. QUESTION 43 Which of the following statements about mutation is correct.

We will be reviewing what we know about mutations and then selecting the statement that has the best answer about how mutations relate to a le. A and b are correct e. Mutations are always caused by chemicals or radiation.

All of the above. Which one of the following statements about mutation types is correct. Correct not all mutations are harmful.

Which of the following statements is true. However those occurring in germs cells are passed to the offspring while those in somatic cells remain confine to the individual only. C Most mutations are harmful or neutral to the organism in which they occur.

Which of the following statements is correct. 3 The environment can cause genetic variation. The correct option is D Mutations inhibit production of telomerase.

Mutations may occur during DNA replication or transcription. Germline mutations are potentially dangerous as they. The statement which is correct regarding prokaryotic genetics is.

Not all the mutations are fatal. Some mutations could even have. 1 Asexual reproduction always produces genetic variation.

Most mutations are harmful so evolution proceeds more rapidly when no mutations occur. It is generally a depolarizing event resulting from inward. Some mutations can be deadly harmful or have no effect.

B Neutral mutations are changes in DNA sequence that are reversed by a second mutation resulting in the same amino acid as the original unmutated. A change in DNA sequence may change the pattern of protein folding resulting in genetic disease. C Usually multiple mutations are required in different genes to cause cancer.

These changes might occur during the time of replication due to any error or it might be caused due to chemical or environmental factors. 2 Gamete production is the only possible source of genetic variation in sexual reproduction. A prokaryote can be.

Consider the following statements. A deletion mutation results in the loss of a base in the dna sequence. 1 Which two of the following statements about genetic variation are correct.

E None of the other answer options is correct. Mutations affect proteins but not the DNA. Option D is incorrect because mutations are not always inherited they are caused due to changes in the DNA.

A Mutations are almost always random with respect to the needs of the organism. Other options are incorrect like option A is incorrect because not all mutations lead to genetic diseases. 1 hour agoMatch the following terms and definitions.

Mutations can occur spontaneously. Can be passed on to offspring. A frameshift mutation affects only the codon directly after the addition or deletion.

Multiple alleles a copying mistake made during DNA replication. It is possible for the substitution of one base for another to have no effect on an organism. A mutation in a 5 splice site will always lead to a shorter mRNA.

Cancer is caused by increased telomerase activity making the cancerous cells immortal and not by inhibition of telomerase production. Point mutation is a process by which new alleles of a gene are produced b. D Usually a single mutation is all that is required to cause cancer.

Cigarette smoke is a significant cause of mutations. A Cancer can only occur with a mutation in a somatic cell. Average mutation rates vary among taxonomic groups.

Hence option C best describes the mutations. Which of the following statements about receptor potentials is false.
