What is the complementary messenger sequence for the DNA sequence?
The complementary mRNA sequence will be ‘G-U-U-C-C-A’. (Option C) An mRNA is the messenger RNA molecule that is synthesized from a double stranded DNA during transcription. The synthesised mRNA will have base sequence complementary to the template strand of the DNA.
What is messenger RNA complementary to?
Messenger RNA is a large family of RNA molecules that are complimentary to DNA molecules and convey genetic information from the DNA to be translated by ribosomes into proteins (Brenner et al., 1961). mRNAs, like DNA, are nucleic acids that contain a specific sequence of nucleotides.
How many nucleotides are in a sequence of messenger?
A sequence of three nucleotides in messenger RNA makes a codon for an amino acid.
Which mRNA nucleotide is complementary to guanine?
cytosine
Guanine always bonds with cytosine, which makes them a pair of complementary bases.
How many nucleotides are in the sequence?
DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA “sentences” within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.
How many nucleotides are in A sequence of messenger RNA codes for an amino acid?
three-
Figure 1: In mRNA, three-nucleotide units called codons dictate a particular amino acid.
What DNA pairs are complementary?
In DNA, adenine (A) and thymine (T) are complementary base pairs, and cytosine (C) and guanine (G) are also complementary base pairs, explaining Chargaff’s rules (Figure 7).
How do you write a complementary nucleotide sequence?
Complementary Nucleotide Sequences Because of the nature of complementary base pairing, if you know the sequence of one strand of DNA, you can predict the sequence of the strand that will pair with, or “complement” it. Remember, when writing complementary DNA sequences, you need to write the sequence in the 5′ to 3′ direction.
How do you reverse a DNA sequence?
This usually involves reversing the sequence after writing it complementary to the one you are given. Give the DNA sequence that will pair with the following stretches of DNA. Question 1 simulates the first step, finding the complementary sequence. Question 2 adds the second step, reversing the sequence to give the proper 5′-3′ orientation.
What is the enzyme that catalyzes the covalent bonding of RNA nucleotides?
RNA polymerase The enzyme that catalyzes the covalent bonding of free RNA nucleotides into a continuous strand, using the sequence of bases in NA as a template, is called ________. one-gene, one-protein hypothesis
