How are transcription and translation related in terms of gene expression?
DNA is used to make mRNa in transcription and then mRNA builds amino acids into proteins during translation
Transcription happens in the ribosomes and translation occurs in the nucleus.
Translation occurs in the nucleus and transcription follows by making amino acids.
Transcription uses proteins to make mRNA, and translation uses mRNA to copy DNA in the nucleus.
DNA is used to make mRNa in transcription and then mRNA builds amino acids into proteins during translation.

universal solvent
_______________ discovers that all cells come from pre- existing cells.
Walther Flemming (not 100 percent sure this is accurate)
What explains the interrelatedness of photosynthesis and cellular respiration?
Photosynthesis and cellular respiration are not at all related.
Cellular respiration makes sugar and oxygen, which are used in photosynthesis to create ATP.
Photosynthesis and cellular respiration both use carbon dioxide and oxygen as reactants to ATP.
Photosynthesis produces oxygen and sugar, which are used in cellular respiration to produce ATP, and cellular respiration produces carbon dioxide and water, which are used in photosynthesis.
Photosynthesis produces oxygen and sugar, which are used in cellular respiration to produce ATP, and cellular respiration produces carbon dioxide and water, which are used in photosynthesis.
Which is a mutation that does NOT result in a phenotypic change (a change that can be seen in an organisms appearance)?
a.A mis-sense mutation that changes the amino acid that is brought down by the tRNA which results in a trait difference.
b. A silent mutation that changes a single base, but the changed codon codes for the same amino acid as the original.
c. A non-sense mutation that causes a stop codon to end the gene sequence- not allowing the protein to finish being made.
b. A silent mutation that only changes a single base, but the changed codon codes for the same amino acid as the original.
ATP and ADP play a role in cellular reactions involving energy. How are these two molecules related?
A. Adding a phosphate group to ATP produces ADP and releases energy.
B. Adding a phosphate group to ADP produces ATP and releases energy.
C.ADP breaks down to produce ATP and a phosphate group, releasing energy.
D. ATP breaks down to produce ADP and a phosphate group, releasing energy.
ATP breaks down to produce ADP and a phosphate group, releasing energy.
Which statement is true about mitosis and meiosis?
Mitosis creates four genetically identical haploid cells, , while meiosis creates two diploid cells that are genetically diverse.
Mitosis results in two genetically identical diploid cells, while meiosis results in four genetically diverse haploid cells.
Mitosis occurs only in gamete formation.
Mitosis produces genetically identical cells and occurs during sexual reproduction, while meiosis produces genetically diverse cells and occurs during asexual reproduction.
Mitosis results in two genetically identical diploid cells, while meiosis results in four genetically diverse haploid cells.

A. glycolysis
B. aerobic respiration
C. aerobic fermentation
D. anaerobic respiration

What describes the result of DNA replication?
DNA replication results in offspring that have the exact same genetic information as both parents.
DNA replication results in two identical strands of DNA- one being the original and the other being the new strand.
DNA replication occurs in G1 phase and results in all cells genetic informtion being different.
DNA replication produces two different DNA strands.
DNA replication results in two identical strands of DNA- one being the original and the other being the new strand.
