Why is a molecule of DNA/RNA anti-parallel?

One strand is the leading strand, and the other strand is the the lagging strand

One strand runs 3' to 5' while the other runs 5' to 3'

One strand likes to connect the way it wants to when it does

DNA replication is which of the following?

Doesn't really get into politics

Why are complementary base pairs important during DNA replication?

The pairs code for specific genes

It helps with conserving the base sequence during replication

Codons are important in maintaining the sequence

Why dos the generation 2 in Messelson and Stahl's experiment support the semi-conservative model of DNA replication?

The E coli had one strand of 15 N DNA and one strand of 14 N DNA

It does not support the semi-conservative model

RNA was found after use of both proteins

The E Coli coded differing proteins after exposed to the composite chemicals

What is the correct order for the process of transcription?

RNA polymerase opens the DNA; RNA polymerase binds the promoter region; RNA and DNA nucleotides are paired up; RNA nucleotides provide energy to create a RNA strand; Transcription stops at terminator;

RNA polymerase binds the promoter region; Transcription stops at terminator; RNA polymerase opens the DNA; RNA and DNA nucleotides are paired up; RNA nucleotides provide energy to create a RNA strand;

RNA nucleotides provide energy to create a RNA strand; Transcription stops at terminator; RNA polymerase opens the DNA; RNA and DNA nucleotides are paired up; RNA polymerase binds the promoter region;

Transcription stops at terminator; RNA nucleotides provide energy to create a RNA strand; RNA polymerase opens the DNA; RNA and DNA nucleotides are paired up; RNA polymerase binds the promoter region;

A sequence of meaningless letters

How has information about methods of hormone production impacted the medical field?

The same gene codes for insulin in humans and in E. coli

In what direction does DNA polymerase add bases onto the template strands? What implication does this have for the addition of bases on the growing strands?

Only the antisense strand is transcribed

Only the sense strand is transcribed

Distinguish between coding and non-coding regions of DNA

Coding sequences code for production of a specific protein, and non-coding is structural DNA at the end of DNA

Non-coding code for production of a specific protein, and coding sequences is structural DNA at the end of DNA

Proteins are used to make non-coding parts of the DNA and enzymes are used to make the coding parts

Enzymes are used to make non-coding parts of the DNA and proteins are used to make the coding parts

How can non-coding regions can be involved in gene expression?

It defines the structure of the chromosomes

It does not impact the gene expression

When DNA uncoils due to outside factors; the non coding parts unravel quicker

DNA does not have non-coding parts

Why are non-coding tandem repeats more useful than coding regions in DNA profiling?

They show variation between people , and can be used more efficiently in DNA profiling

They are not used in DNA profiling

The codons are easier to read when they are non-codons

They are shorter and easier to define
