Which process synthesizes proteins?
Translation?

What is one application of DNA profiling?
To identify victims (forensic cases) or confirm biological relationships (paternity) or determine relationships between populations(evolution/migration)
100
When does DNA replication occur?
During cell division
200
What are three differences between DNA and RNA?
RNA has ribose, DNA has deoxyribose; RNA has uracil, DNA has thymine; RNA is single stranded, DNA is double stranded
200
What would be the corresponding mRNA nucleotide sequence for this DNA sequence, "GAT?"
CUA
200
What type of RNA carries the codon to synthesize proteins?
tRNA
200
What is the process that separates DNA fragments?
Gel electrophoresis
200
What is the role of RNA and DNA?
RNA enables the information of DNA to be expressed through proteins. DNA is responsible for storing genetic information.
300
What kind of bond is formed between the phosphate group and sugar in DNA?
Phosphodiester bond
300
What are the two types of bonding that are present in nucleic acids or between nucleotides?
Covalent and hydrogen bonding?
300
What is the process of transcription?
Two strands of DNA are separated by breaking h-bonds.
Each strand is a template for mRNA.
Free floating nucleotides are used to base pair to form mRNA.
300
What is the role of the polymerase chain reaction (PCR)
Used to amplify specific regions in DNA by making multiple copies.
300
What are the building blocks of nucleic acids? be specific.
Pentose sugar, phosphate group, and nitrogenous base
