what is the purpose of the cell cycle and what happens when the process involved awry?
A. Cell division or mitosis is part of the cell cycle and cells undergoing mitosis in multicellular organisms are used for development, growth and repair
B. Apatosis genes encourage cell division, while tumor suppressor genes inhibit cell division.
C. Cell communication keeps the cell cycle in check because errors during the cell cycle can have negative results for the organism such as the development of cancer.
D. Tumor suppressor genes encode proteins that serve as a brake on cell growth and are routinely activated at checkpoint D.
E. if a cell receives restrictions from the G1 checkpoint and cannot continue into the next phase, the cell can enter the G0 (resting stage) until conditions can improve
F. Cyclin dependent kinases (Cdk) are protains that work right cyclin regulatory proteins and are associated with different checkpoints of the cell cycle.
(im sorry for the photo, that's the only thing I could do)
Answers
Answer:
A and E
Explanation:
The cell cycle is important because. during the process, cell division in the form of mitosis takes place. The division of cells is important for an organism's growth, development, and repair.
The cycle has different checkpoints in which things are monitored in order to ensure that it is error-free. The checkpoints include G1, G2, and M checkpoints. If things go awry at any part of the cell cycle, the cell either cease dividing and enters a resting (G0) or tries to fix the issue before proceeding.
The correct options are A and E.
The purpose of the cell cycle and what happens when the process involved awry - option A, C, E, F.
The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cells
mitosis is part of the cell cycle and cells undergoing mitosis in multicellular organisms are used for development, growth and repair The G1 checkpoint takes into consideration that whether all the conditions are suitable for the cell division to advance. In the G1 checkpoint, the cell, which does not qualify all the requirements, will not be permitted to advance into the S phase.CDKs are proteins that play important roles in the control of cell division and modulate transcription with association with different checkpoints of the cell cycle.Thus, the purpose of the cell cycle and what happens when the process involved awry - option A, C, E, F.

C.
Explanation:
thats just his first law of motion
Answer:
C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.
Explanation:
In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

8. nucleotides
9. RNA polymerase
10. 2 and 1
11. messenger between the genetic information in DNA and the amino acid sequence of proteins in protein synthesis through central dogma.
12. wind up
Explanation:
After the transcription mRNA moves from the DNA to the ribosome out of the nucleus to perform the translation and produce amino acid chains. A Ribosome is the site of protein synthesis.
DNA or RNA both nucleic acids are made up of basic units known as nucleotides that join together to form ribonucleic and deoxyribonucleic acid.
RNA polymerase is the enzyme that binds with the DNA molecule and adds complementary sequences to build mRNA.
DNA molecules are double-stranded molecules that are attached to one another by the hydrogen bonds between the nitogenous basses whereas RNA molecules have only one strand in the structure.
mRNA plays the role of messenger between DNA molecule and ribosome molecule to carry out the genetic information coded in the DNA molecule to produce amino acids in the particular sequence to produce protein.
The formation of new DNA from the old DNA is called Replication and the formation of RNA from the DNA is said to be translation.
The central dogma of DNA defines the following:-
ReplicationTranscriptionTranslationThe answer to the following is as follows:-

Answers
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

The marine biologist from the nursery is planning to develop a large number of new coral polyps with large stinging tentacles. Identify the type of reproduction the marine biologist should use to develop the new coral and explain why this type of reproduction is preferable.
Answers
Answer:
Sexual reproduction.
Explanation:
Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answers
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.
Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.
Answers
The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.
What is transcription?The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.
In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.
This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.
The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.
Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.
