Which feature of DNA enables a single-stranded DNA probe to hybridize with a single-stranded target gene?
The complementary base pairing between adenine (A) and thymine (T), and cytosine (C) and guanine (G) allows a single-stranded DNA probe to hybridize with a single-stranded target gene. This specificity is key for detecting and identifying specific sequences in the target gene through base pairing interactions.
What is the role of the primers in PCR?
Primers in PCR serve as the starting point for DNA synthesis, initiating the amplification process by binding to the target DNA sequence. They provide the necessary template for DNA polymerase to extend and replicate the target sequence during each cycle of the PCR reaction. The specificity of the primers determines which DNA region will be amplified, allowing for targeted amplification of the desired sequence.
Which of the three main steps of pcr is responsible for the specificity in the small piece of DNA that gets amplified by replication?
The annealing step is responsible for specificity in PCR. During this step, the primers bind specifically to the target DNA sequence, allowing for amplification of the desired fragment.
The order of nitrogenous bases in DNA determines the order of what in organism?
The order of the Amino Acids in the protein chain.
What property of DNA makes it possible for a probe to find a single-stranded DNA target gene?
a DNA molecule has two paired strands. ~
What is the relationship between an organism's DNA and protein specificity?
An organism's DNA encodes the instructions for building proteins through the sequence of nucleotides in its genes. This sequence determines the specific sequence of amino acids in a protein, which in turn influences its structure and function. Therefore, the DNA sequence directly influences the protein specificity in terms of its unique composition and role in the organism.
What is a sense probe in insitu hybridisation?
A sense probe in in situ hybridization is a nucleotide sequence that is complementary to the target RNA or DNA sequence of interest, allowing for the detection of specific genes within tissue samples. Unlike antisense probes, which bind to the target sequence to visualize gene expression, sense probes bind to the non-template strand and serve as a control to confirm the specificity of the hybridization signal. The presence of a signal with a sense probe typically indicates non-specific binding, while a lack of signal supports the specificity of the antisense probe results.
Which feature of DNA enables a single-stranded DNA probe to hybridize with a single-stranded target gene?
The complementary base pairing between adenine (A) and thymine (T), and cytosine (C) and guanine (G) allows a single-stranded DNA probe to hybridize with a single-stranded target gene. This specificity is key for detecting and identifying specific sequences in the target gene through base pairing interactions.
Which explains how a probe can find a single-standard target DNA gene?
The probe is the second strand of DNA that forms double-stranded DNA with the target gene.
The secret of DNA has to do with the sequence of what along the DNA ladder?
The sequence of the nitrogenous bases, which are the 'rungs' of the DNA 'ladder' are what give DNA its specificity.
What describes the structure formed wjen a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
What is the role of the primers in PCR?

A short stretch of DNA that can be distinuished from other molecules due to radioisotope labeling is a a gene library b DNA sequencer c probe d DNA fingerprint?

How do scientist locate a specific gene in a genomic library?
Scientists use a nucleic acid probe where scientists treat the DNA being searched with chemicals or heat to seperate the two DNA strands, then the nucleic acid probe is mixed with the single strands and the probe tags the direct DNA portion.
How does DNA affect an orginsims traits?
DNA carries the genetic information that determines an organism's traits. The sequence of nucleotides in DNA determines the sequence of amino acids in proteins, which are essential for an organism's structure and function. Mutations in DNA can result in changes to an organism's traits.
What describes the structure form when a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
What describes the structure formed when a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
