In dna sequencing, how does the addition of dideoxynucleoside triphosphates (ddntps) terminate the synthesis of new dna? \
son4ous [18]

ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.

ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.

The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

al has a pet cat. one day he observes that it is scratching and urinating on tree trunks in his yard. what behavior is al's cat
astra-53 [7]

Al's cat is displaying territoriality by marking his territory by marking territory with urine and scratches.

Territoriality

Territoriality is the defense of the area where an organism lives. The marked area is often regarded as the territory of the animal living there. Al's cat is marking its territory by urinating on the plants and scratching them. Other animals that enter the territory of the cat will be able to know that the territory is not theirs and keep themselves away from the same. If an animal invades the territory of another animal it might get attacked by the animal whose territory it just invaded.

Marking the territory often comes with many perks as the animal is able to lay claim to the food, nest locations, shelter, interactions with mates, etc. The animal is able to monopolize the space in which they live.

IgorC [24]

Complete Question:  

What would most likely be included in the “Analysis” section of a lab report?

1) a discussion of any errors in the experimental data

2) a list the supplies that were used in conducting the experiment

3) suggestions for new experiments based on the results

4) a description of what the dependent and independent variables were

Answer:

1). <u>a discussion of any errors in the experimental data</u>.

In the analysis section of the lab report, after analyzing and investigating the data, errors are identified in the experimental data. Furthermore, discussion carried out to point out those error occurred in the data. In an analysis process discussion is carried out to find the errors in the whole process. In this process all facts and figure are gather to inquire if there are any errors or mistake present in the final values or final result. Analysis section in a lab report has a key role because it make sure that the final result is error free.
