What would the base sequences on the other strand of Dna be?
They would be described as being complementary - as in complementary base pairing.
A search for sequences that are complementary to the desired sequence of a DNA fragment uses a technique called?
Hybridization
What are the introns and exons?
An intron is a DNA region within a gene that is not translated into protein. After intron splicing (ie. removal), the mRNA consists only of exon derived sequences, which are translated into a protein.
In genetics what does complementary DNA mean?
Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme. cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).
What is the small pieces of DNA that are edited out of the mRNA message before it is expressed?
During the transcription, when the mRNA is being processed, the introns are removed and the exons are connected together.

What are exons and introns?
Intronsare intervening sequence of DNA; does NOT code for a protein.Exons are expressed squence of DNA; codes for a protein.
What is the difference between an intron and exon?
Exons code for amino acids (they are usable codons) Introns code for nothing.
Can clones isolated from cDNA libraries contain promoter sequences?
C DNA library lack information about introns and regulatory sequences like promoter , enhancer etc.
How did the complementary relationship between the sequences of nucleotides lead to the discovery of DNA replication?
this is bull

Two pieces of DNA can be joined to form a single piece only if they?
Have single chain ends with complementary nucleotide sequences
What do you call a short piece of DNA that codes for a certain protein?
DNA does not make proteins directly. Rather, the DNA is the mother-of-all recipes that specialized transcription proteins (tRNA) read to make messenger RNA (mRNA). mRNA is the specific recipe to make specific proteins. The specific code of DNA are made of regions called introns and exons. Exons are what the gene has coded for and introns are "spacers". I remember exons are exactly what is needed and introns are intervening sequences.
