Flashcards in Review of basic concepts Deck (38)
RNA is produced from DNA via a process called____
DNA reproduces itself via a process called_____
RNA then directs the production of proteins through a process called____
Cells that are functioning normally produce and replicate ____ ____ and ____ as indicated in the flow diagram.
Nucleic acid and proteins
List two functions of DNA
Stable storage of genetic information & Transmission of genetic information.
Stable storage of genetic information is the source of information for synthesis of __ ____.
Transmission of genetic information is the template for _____ of genetic information.
List four nitrogenous bases found in DNA nucleotides.
Adenine (A), Cytosine (C), Thymine (T), and Guanine (G).
List two purine base
A and G
List two pyrimidines base.
T and C
Thymine always binds to ____
cytosine always binds to ___
DNA is a double stranded molecule with ___ arrangement. Which bonds holds the strands together?
Helical; Hydrogen bonds.
DNA strands that are bound together are called _______
The _____ bases make up DNA nucleotides.
Each nucleotide has a _____- _____ - _____ _____
Deoxyribose tri phosphate base
The end of each chain that has the phosphate group is called the _____
The end of each chain that has the OH group is called the ____
The arrangement in which the two complementary chains have their 5' and 3' ends in opposite directions is described as
The nucleotide complex includes the deoxyribose triphosphate + nitrogenous base. Give a example.
dATP for adenine
An enzyme that untwists and separates double stranded DNA strands.
The point at which the replication takes place is called the
An enzyme which attaches to each strand of the DNA and begins adding complementary nucleotides in a 5' to 3' direction.
One strand which undergo continuous replication by the simple addition of bases that are complementary to the original strand.
The other strand which undergo discontinuous replication in pieces of about 1000 base pairs called
Okazaki fragments which happens on lagging strand.
An enzyme which fills in the gaps between the Okazaki fragments on the lagging strand.
How is RNA differ from DNA?
RNA is single stranded. The sugar in the RNA backbone is ribose. and the nitrogenous base uracil is included in the RNA. Nucleotides in RNA are noted as rATP or ATP rather than dATP as in DNA.
Instead of the Thymine found in DNA, what is found in RNA?
DNA codes for production of ____ during transcription.
