Insert the type of repair system that might be able to fix the damage before it gets set in the genome AND the type of mutation that the DNA damage may cause if it is NOT fixed in time.

. UV light exposure B. Environmental factors such as chemicals radiation and ultraviolet light from the sun can cause mutations. DNA fails to copy accurately.

Errors occurring during DNA replication D. Which of the following isare likely the results. Thalassemia Phenyl ketonuria alcaptonuria and many other human diseases are caused by simple base substitution in the nucleotide that prevents synthesis of normal protein.

This enzymes shape is not affected by pH. A genetic mutation causes a disease when the the DNA encodes is altered such that it no longer functions properly. Most of the mutations that we think matter to evolution are naturally-occurring.

Which of the following can cause a mutation in a gene. Which of the following are possible causes of genetic mutation except one. Genetic markers can indicate genetic disorders because fragments resulting from treatment of the DNA with a restriction enzyme are different for people with a genetic abnormality.

For example when a cell divides it makes a copy of its DNA and sometimes the copy is not quite perfect. Genetic mutations are slight alterations of DNA or RNA nucleotides genes or chromosomes that may occur during replication or cell division. Which of the following is associated with that weak response.

Incorrect answer is insertion mutation nucleotideas somatic cell doesnt go insertion sequence. The lac operon is an __________ operon. Sometimes the copy of the DNA is not perfect and this slight difference from the original DNA is called a mutation.

Germ line mutations occur in the eggs and sperm and can be passed on to offspring while somatic mutations occur in body cells and are not passed on. This alteration results in the replacement of glutamic acid by valine. A aversion to the smell and taste of alcohol B higher risk of alcoholism C aversion to the physical effects of alcohol D.

Type of gene mutation which involves the replacement of purine with pyrimidine or vice versa or the substitution of one type of base with another type of base is a transition b transduction c translation d transversion. The mutation is caused due to the following reasons. Substitution Transition or Transversion and Indel.

There are genetic mutations that cause a weak response to alcohol. Click or tap a choice to answer the question. Mutations can also occur as the result of exposure to environmental factors such as smoking sunlight and radiation.

Gene mutations although cause minute change in the base pairing its impact is largely felt by the organisms bearing such mutant gene. Mis-sense mutation is when the meaning of codon changes from one amino acid to another it is called missense mutation. Explain the diseases caused by single gene mutations following mendelian inheritance specifying the genomic location asked Oct 18 2019 in Biology by RiteshBharti 539k points cbse.

All these mutations lead to evolution. The causes of mutations. Environmental damage such as radiation toxic chemicalspollutants ____19You have a DNA sequence that codes for a protein and is as nucleotides long.

The DNA sequence of a gene can be altered in a number of ways. A genetic mutation causes the three-dimensional shape of a photosynthetic enzyme to change but the active site is unaffected. Chromosomal inversions S-phase interruptions nucleotide insertion mutation nucleotide deletion mutuation DNA segment duplications.

Down syndrome is caused by three copies of chromosome 21 also known as 21. Genetic disorders can be caused by a mutation in one gene monogenic disorder by mutations in multiple genes multifactorial inheritance disorder by a combination of gene mutations and environmental factors or by damage to chromosomes changes in the number or structure of entire chromosomes the structures that carry genes. Random uncorrected errors may be beneficial or harmful in relationship to evolution.

During cell division the DNA makes a copy of its own. Genetic disorders can be caused by a mutation in one gene monogenic disorder by mutations in multiple genes multifactorial inheritance disorder by a combination of gene mutations and environmental factors or by damage to chromosomes changes in the number or structure of entire chromosomes the structures that. Other mutations are caused by errors made during mitosis and meiosis.

A human disorder called sickle cell anaemia is caused by a single base substitution in a gene. 2 Errors during __ _ can cause genetic problems with the resulting germ cells. Most of the mutations occur when the DNA fails to copy accurately.

All of the following are ways that gene mutations can occur EXCEPT. These changes result in errors in DNA replication and transcription. Mutations can result from DNA copying mistakes made during cell division exposure to ionizing radiation exposure to chemicals called mutagens or infection by viruses.

External influences can cause mutations Mutations can also be caused by exposure to specific chemicals or radiation that cause the DNA to break down. A genetic _____ is an abnormality in an individuals gene sequence which can be used to test for genetic disorders like Huntington disease. These mutagens alter DNA by changing nucleotide bases and can even change the shape of DNA.

Gene variants also known as mutations can have varying effects on health depending on where they occur and whether they alter the function of essential proteins. That small difference from the original DNA sequence is a mutation. Mutations can be caused by the following types of DNA damage.

The lac operon in Ecoli regulates genes that code for enzymes required for breakdown of lactose. Which one or more of the following outside factors may cause mutations. The gene that controls the rate of mutation of another gene is a mutator gene b inducer gene.

Marker True or false. A silent mutation is a change in the DNA that does not change the encoded. There would be no effect on normal enzyme function.

Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations happen for several reasons.
