Frameshift mutation is a type of genetic mutation wherein a change in sequence and order is caused, which is not by altering three nucleotides. Examples of this are insertions of bases or deletions of bases. The correct answer is A since A base or adenine is deleted causing a different reading frame.

<span>The correct answer is A) AGTCG.</span> The frameshift mutations are mutations that include insertions and deletions which, as a consequence, change the number of nucleotides in a DNA sequence that is not divisible by three. Because of the triplet nature of gene expression by codons the reading frame is altered, resulting in a completely different translation from the original. <span>In this case, deletion of the A (adenine) nucleotide occurred.</span>

Why is inter phase important to an organism?
Katyanochek1 [597]
Interphase is when the cell grows and duplicates chromosomes. This is important for the cell to divide, because otherwise, the cell would shrink everytime it divided and would not have a sufficient amount of DNA

A scan of Sam's genome for the 100 most common mutations known to cause RP didn't find anything. How can you explain this result
yan [13]

Answer:

He is either not carrying the gene for RP or the RP gene has mutated.

Explanation:

RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.

The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.

Explain how the daily energy needs are different between the zebra and its predator, the lion. Be certain to include any pertine
Snezhnost [94]

Answer:

Both animals eats different types of food so they have different digestive system.

Explanation:

The daily energy needs are different between the zebra and its predator, the lion because they have difference in daily activities and they eat different types of food and. Zebra is herbivorous animal while the lion is carnivorous so there is highly difference occurs in their digestive system. Zebra activities is to eat plants and run from the prey which needs more calories but the lion needs very high amount of calories for catching their pray for food.

Members of the Deinococcus genus present an interesting conundrum to scientists who try to classify them as either gram-positive
AURORKA [14]

Answer:

Explanation:

Bacteria can be classified traditionally into two broad categories according to their cell wall, which are Gram-positive bacteria and Gram-negitive bacteria.

Gram-positive bacteria are bacteria that produce a positive result when Gram stain test is performed. It takes up the crystal violet stain of the test, and then show a purple-coloured appearance when seen through an optical microscope. This is as a result of the thick "peptidoglycan" layer in the bacterial cell wall which retains the stain used in the cell after washing it away from the rest of the sample.

Gram-negative bacteria after the decolorization don't retain the violet stain,the outer membrane of gram-negative cells is degraded by the alcohol.The peptidoglycan layer is positioned and between the membrane and a bacterial outer membrane, causing them to take up the counterstain and made appear red or pink.

Therefore, Deinococcus is one genus of the bacterial phylum that have resistant to environmental hazards. They posses thick cell walls that give them Gram-positive stains, but they also posess second membrane that made them them closer in structure to Gram-negative bacteria, which present an interesting conundrum to scientists who try to classify them as either gram-positive or gram-negative.
