How accurate is DNA and fingerprint technology, and when did it emerge? What level of human error still plays a role in this typ

Firdavs [7]

Answer:

DNA and fingerprint technology is said to be very accurate as it uses chemicals to separate strands of your own unique DNA to reveal the unique parts of your genome. which is your genetic make-up

This technology emerged in 1984 and invented by Professor Sir Alec Jeffreys who realized that you could detect variations in human DNA, in the form of these mini-satellites to produce a pattern unique to an individual

Human error still plays a role in terms of lab staff who make errors in conducting the DNA analysis, interpreting it or reporting the results of the analysis sometimes it occurs in entering the resulting DNA profile into a DNA database system which may result from a failure to comply a procedure, misjudgement, or some other mistake. There are protocols and precautions which can be introduced to minimise the opportunity for error during analysis or interpretation, however, the potential for human error cannot be fully eliminated.

What are the mRNA triplets coded for from this gene? A) GGG UUC ACC B) CCC AAG TGG C) GGG TTC ACC D) UUU CCC AGA

Complete question:

A gene on strand of DNA has the following nucleotide sequence: CCCAAGTGG

A) GGG UUC ACC

B) CCC AAG TGG

C) GGG TTC ACC

D) UUU CCC AGA

Explanation:

What are the mRNA triplets coded for from this gene?

A) GGG UUC ACC

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

Why are proteins considered organic molecules?

snow_lady [41]

Answer:

A) They contain many carbon atoms.

Explanation:

Proteins are considered organic molecules because they are made up of carbon atoms. Proteins give your body energy and allows your body to run the way it does. Proteins also aren't considered organic molecules because they are small, because they are not used by living things, or because they contain nitrogen.

Hope this helps.

Which specific subdivision of the nervous system calms the body after strenuous physical activity?

7nadin3 [17]

The answer to this question would be: parasympathetic division

Parasympathetic nervous is part of the autonomous nervous system. In the autonomous nervous system, the sympathetic system is used when you enter the "fight or flight" mode. In this case, the body will be prepared to be able to take a decision as quickly as possible in a strenuous state. The nervous also cause an increase in the heart and breathing rate to increase body capability.
Parasympathetic is the opposite of it which was activated to calm the body so it can maintain the normal body function.
