transcription and translation

from DNA to DNA from DNA to RNA from RNA to protein which option identifies the processes listed?

scientists are working to design the genetic code of an organism they intend to create in a lab. Which nucleotides can they use to sequence the DNA of the organism?

A,C,G,T

the amino acid methionine is coded for in humans by the mRNA nucleotide sequence: adenine-uracil-guanine, or AUG. Which statement is true regarding this amino acid?

AUG would also code for methionine in every other organism on earth

a student was asked to list the possible ways genetic information is transferred between DNA, RNA, and protein for an assignment. Which table should the student include in her assignment?

DNA - RNA DNA - DNA RNA - protein

the continuity of life-forms on earth is a result of the cellular processes that ensure genetic information is passes from parent to offspring. These processes involve two essential structures, nucleic acids and proteins, which diagram represents the correct sequence of these processes?

DNA - RNA - amino acids - proteins

which series of steps describes the process of how traits are created from the genetic code?

DNA - mRNA - proteins - traits

the sequence of nucleotides in DNA codes for specific amino acids. Based on this information what is an accurate description of the function of DNA?

DNA carries the information for formation of the proteins in each organism.

what is the proper sequence of events during protein synthesis?

DNA is transcribed into RNA in the nucleus; the RNA then travels to ribosomes where it is translated into amino acids

what are the 5 nitrogenous bases that are found in every organism?

adenine, cytosine, guanine, thymine, and uracil

which statement explains why all mango trees look similar?

all mango trees have genes that code for many of the same proteins.

what is the sequence of DNA that contains information to synthesize a specific protein molecule?

gene

why is DNA considered to be the code of life?

it contains information to form proteins

what will the arrangement of the amino acid in the polypeptide formed? uuacaaguugggaugugg

leu-glu-val-gly

A researcher is designing a chemical to interfere with the formation of peptide bonds between amino acids. The formation of which type of molecule will be inhibited by the chemical?

protein

human - ccaagatgg chimpanzee - ccaagatgg dog - ccaggatgg mouse - gcgaaatgg what can be concluded from the data?

the DNA found in every organism is made up of four different types of nucleotides.

which factor most directly influences the sequence of amino acids in a protein?

the arrangement of nucleotides in the DNA

which situation would most likely occur if all the ribosomes in a cell were destroyed?

the cell would no longer synthesize chains of amino acids.

which statement about nucleic acids in living organisms is correct?

the nucleotide sequence AGC CCT CAG could be found in the DNA of both humans and bacteria.

which statement about nucleic acids In living organisms is correct?

the nucleotide sequence AUC CGA GCU could be found in the RNA of both prokaryotes and eukaryotes

a scientist injects a drug into a mouse that inhabits the formation of mRNA in either the sperm or egg cell. what could be the result of this alteration?

the process of protein synthesis will stop

which statement summarizes the relationship between DNA, proteins, and amino acids?

the sequence of nucleotides in DNA codes for specific amino acids which bond to form proteins.

which option identifies the correct sequence of events involved in protein synthesis? w. formation of peptide bond x. attachment of mRNA to the ribosome y. formation of bond between amino acid and tRNA to form a complex z. binding of the newly formed complex with mRNA

x-y-z-w

how should the student sequence the steps to show the process correctly in the model? w. amino acids form polypeptide chain x. mRNA is transcribed from DNA y. Ribosomes translate mRNA z. mRNA leaves nucleus

DNA and RNA are responsible for carrying hereditary information in all living organism. Along with carbon hydrogen and oxygen what are the two other elements that compose the structure of DNA and RNA?

nitrogen and phosphorus
