What is the difference between positive strand and negative strand viruses?
A positive strand virus is immediately contagious. A negative strand virus has to create proteins to convert into a positive strand virus. it is not contagious until it becomes a positive strand.
If a strand of DNA has the sequence aagctc transcription will result in?
If a strand of DNA has the sequence aagctc, transcription will result in a mRNA molecule with the complementary sequence uucgag. Transcription is the process of creating a mRNA molecule using DNA as a template.
Does the process of DNA replication result in a copy of the original strand of DNA?
The process of DNA replication is semi-conservative. Which means, in the new (daughter) DNA double helices that are formed, one strand belongs to the parent strand (also referred to as the template strand) and the other is a newly synthesized strand. Subsequently, every new DNA molecule that is formed as a result of the replication process has one original parent strand and one newly synthesized complimentary strand.
When you read a DNA sequencing gel from the bottom to the top is what you read called the coding strand or the non-coding strand?
When reading a DNA sequencing gel from bottom to top, you are reading the sequence of the complementary non-coding strand of DNA. This is because the gel displays the sequence of bands corresponding to the bases in the DNA template strand, which is the non-coding strand.
The cellular process of creating two new DNA molecules from one original copy is called replication Which statement is the BEST description of this process?
During DNA replication, the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. Enzymes called DNA polymerases add nucleotides to the growing strand in a direction from 5' to 3'. The end result is two identical DNA molecules, each containing one original strand and one newly synthesized strand.
Is it possible to have a false positive hair strand test for heroin and cocaine?
It's extremely unlikely, the hair test is 99.95% accurate.
What is the difference between positive strand and negative strand viruses?
A positive strand virus is immediately contagious. A negative strand virus has to create proteins to convert into a positive strand virus. it is not contagious until it becomes a positive strand.
Is Hepatitis B RNA or DNA?
HCV is an enveloped single-strand RNA virus in the flavivirus family.
How is a strand test carried out?
a strand test is carried out after applying colour to a hair. You remove the colour of a strand of the hair to check if you have the desired result (colour)
Is mumps negative or positive stranded?
It has negative strand of RNA.
What is the hepatitis A virus?
The hepatitis A virus (HAV or also Hepatovirus A) is a picornavirus species from the family of Picornaviridae, genus Hepatovirus. It contains no capsid, leaving it unenveloped with a single-strand RNA in a protein shell. In humans, HAV can cause an acute infection of the liver also known as Hepatitis A.

What is the result of Transcription?
DNA is converted to a strand of mRNA to be translated in the ribosome.
If a strand of DNA has the sequence aagctc transcription will result in?
If a strand of DNA has the sequence aagctc, transcription will result in a mRNA molecule with the complementary sequence uucgag. Transcription is the process of creating a mRNA molecule using DNA as a template.
Hepatitis virus comes under which type of virus?
Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of virus families. Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus. Hepatitis D which is also known as Delta agent is a circular RNA that is more similar to a plant a viroid than a complete virus.
Does the process of DNA replication result in a copy of the original strand of DNA?
The process of DNA replication is semi-conservative. Which means, in the new (daughter) DNA double helices that are formed, one strand belongs to the parent strand (also referred to as the template strand) and the other is a newly synthesized strand. Subsequently, every new DNA molecule that is formed as a result of the replication process has one original parent strand and one newly synthesized complimentary strand.
HIV virus contain plus strand or minus strand?
HIV is a retrovirus that contains two identical copies of single-stranded RNA with a positive polarity. This means that the RNA acts as mRNA and can be directly translated into proteins by the host cell's machinery.
When you read a DNA sequencing gel from the bottom to the top is what you read called the coding strand or the non-coding strand?
When reading a DNA sequencing gel from bottom to top, you are reading the sequence of the complementary non-coding strand of DNA. This is because the gel displays the sequence of bands corresponding to the bases in the DNA template strand, which is the non-coding strand.
