What process does rna molecules are produced by copying part of the nucleotide sequence of dna into a complementary sequence in rna?
The nucleotide "A" base pairs with the nucleotide "T", Similarly, the nucleotide "C" base pairs with the nucleotide "G", and in the same way, The nucelotides "T" and "G" base pairs with nucleotides "A"and "C" respectively. The complementary nucleotide sequence is thus the base pair with which it forms a double-stranded structue of the DNA, for example the complementary sequence for "ACGTTTA" is "TGCAAAT".
A cluster of three nucleotides is called a 'codon' - However, the term is only really used to refer to refer to a 3 nucleotide sequence on an mRNA molecule. Codons provide a means by which charged tRNA molecules can specifically add amino acids to a growing polypeptide chain. tRNA molecules have the complementary 3 nucleotide sequence (anticodon) that allow the specific recognition.
The nucleotide sequences in the two chains of a DNA molecule are complementary. This means that A (adenine) in one chain always binds to T (thymine) in the other, and C (cytosine) always binds to G (guanine). So if the sequence in one chain is: AATCTGGA the complementary sequence in the other chain will be: TTAGACCT
The process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules is called replication. The two strands of a DNA molecules have complementary base pairs, and so the nucleotide sequence of each strand automatically gives the information needed to produce its partner.
The sequence of nucleotides of the complementary strand will be the nucleotides which bind to the nucleotides of the template. In DNA, adenine binds to thymine and cytosine binds to guanine. The complementary strand will therefore have an adenine where the template strand has a thymine, a guanine where the template has a cytosine, etc. For example: If the template strand is ATG-GGC-CTA-GCT Then the complementary strand would be TAC-CCG-GAT-CGA
Suppose a strand of DNA has the nucleotide sequence ccagattg what is the nucleotide sequence of the complementary strand?
Which do you suppose would be more harmful A mutation that changed the nucleotide sequence of an mRNA molecule or a mutation that changed the nucleotide sequence of a DNA molecule?
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
If one strand of DNA had the sequence taggtac what would be the sequence of the complementary DNA strand?
Sticky ends are produced by cutting the DNA in a staggered manner within the recognition site producing single-stranded DNA ends. These ends have identical nucleotide sequence and are sticky because they can hydrogen-bond to complementary tails of other DNA fragments cut by the same restriction enzyme.
Here's a sample nucleotide sequence: AATUGC If there was a nucleotide deletion (let's say the "G" gets deleted), the sequence would become: AATUC If there was a nucleotide addition/insertion (let's say a "G" was added between "T' and "U"), the sequence would become: AATGUGC The difference is that a deletion makes the DNA shorter and an insertion makes it longer.
