The process of that same framework in question is defined below.

Explanation:

The DNA was indeed prepared by mixing with either a dye as well as a radioisotope which enables the gel to have been recognized. The specific filaments would then be differentiated from one another DNA electrophoresis.

What is RNA primase's job?
-removing a few bases for DNA polymerase
-add a few bases for DNA polymerase
-removing a few bases for helicase

Answers

Answer:

The correct answer is - add a few bases for DNA polymerase

Explanation:

A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.

It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.

tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters

Answers

Answer:

tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).

Explanation:

A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.

What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.

tRNA molecules deliver amino acids to ribosomes where the amino acid  - С. becomes an anticodon.

During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.

Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.

Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid  - С. becomes an anticodon.

Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.

Answers

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

what happens to the chemical bonds during chemical reactions

Answers

During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were.

Fish are considered carbon-based organism

Answers

Answer:

Its how you see it.

Explanation:

1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.

It was the big day; Lance had been training for months in anticipation of the annual “Dasher Twenty-Six-Two.” As he laced up his sneakers, he thought back to the endless grind of aerobic training he had accomplished. Hour after hour of lung-burning, quad frying jogging on pavement and dirty. He was ready mentally and physically, plus he had a secret weapon ready to go. Lance had been experimenting in the use of a thick, sugar saturated gel-nutrition to supplement his running. He anticipated finishing just before the three-hour mark and he planned to eat his special goo around hour two for a much-needed energy boost. The goo solution was a mixture of maltose, sucrose, and glucose, as well as some salt. Water would be available on the course every few miles and with his nutrition plan set he found his way to the line. *BOOM*

The start gun leaked smoke as wave after wave of runner set off. Miles started flowing by… five miles feeling good… Mile thirteen halfway there! Just as the two-hour mark was upon him, Lance pulled the gel from his pocket and slurped the gooey syrup down. Mile fifteen Phew, heavy legs… Mile eighteen Legs are burning but I got it… then came a hit of fatigue.

He had read about this before. The dreaded bonk. Bonking was said to be the final drips of glycogen being removed from the muscle’s cells, with an accompanying burn suggesting rapid production of lactate. It also meant he had spent the last two hours less aerobic than he thought. Making it to mile twenty-two, Lance noticed his heart rate ten-beats over his planned pace. His breath was getting harsher, his legs getting weaker. The mile twenty-four marker went by and he was down to nearly a walk, lips dry and stomach lurching. The last half mile was a blur as Lance crossed the line his raised arms quickly fell, and so did he, right into a chair near the finish line.

Discuss the necessity of Lance’s training to prepare for his ability to fuel a marathon with specific reference to the major organ systems involved and their purpose. Identify the needed reactants and excreted products Lance utilized during his ongoing respiring, with specific reference to where each is created or used. Finally, predict the influence of his experimental goo and suggest advantages and disadvantages to its use, as well as better use with reference to time and impact on the ability to enter and circulate to where it would be needed
