The RNA molecule is usually made up of how many strands? a) 1 b) 2 c) 3 d) 6 What are the four nitrogen bases in DNA? What are the bases for RNA? How many bases are in a codon? In an anticodon? What are some unusual bases of RNA?
DNA-manipulation enzymes- There are specialized enzymes that move along DNA strands and repair them. There are other enzymes that can untwist DNA strands to reproduce them (DNA polymerase). Still others can find small patterns on DNA and attach to them, blocking access to that section of DNA ...
How many codons and how many DNA bases do you have the part of the gene that encodes the enzyme uricase? How are rRNA genes organized in higher eukaryotes? The RNA molecule is usually made up of how many strands? a) 1 b) 2 c) 3 d) 6 ...
For example, two inputs of 1 (DNA strands 1 and 2) would interact with an OR logic gate DNA molecule. Then in a fluid-filled tube, the input oligonucleotide interacted with a logic gate DNA molecule and generated an output oligonucleotide. The output oligonucleotide bound to a different sing...
Dogs have 39 pairs, and some plants have as many as 100. Chromosomes come in pairs. Each chromosome is a tightly packed strand of DNA. There are two strands of DNA joined together at the centromere to form an X-shaped structure. One strand comes from the mother and one from the father...
Cleavage Site: Cuts both strands on both sides of recognition site a defined, symmetric, short distance away and leaves 3´ overhangs. Example: BcgI: /10(N)CGA(N)6TCG(N)12/ /12(N)GCT(N)6ACG(N)10/ Example(s): BcgI, Bsp24I, BaeI, CjeI, CjePI Type IIe(5) Recognition Sequenc...
strands or with uracil in RNA strands). The ability to base pair underlies important biological functions such as replication, transcription, and translation in protein biosynthesis. The sugar molecule in the nucleotides that make up RNA is ribose, a five-carbon sugar in a specific chemical ...
Covid-19 RNA vaccine, illustration. The vaccine consists of strands of mRNA (messenger ribonucleic acid) encased in a lipid nanoparticle sphere (red) surrounded by a polyethylene glycol coat (violet). The mRNA codes for a mutated version of the viral spike protein found on the surface of the...
During replication, newly assembled chromatin is acetylated and may favour an active PRE but challenge a silent one. Several PcG and TrxG proteins remain bound to replicating chromatin and may transmit memory to daughter strands. During mitosis, many proteins dissociate from chromatin and transcription...
A double stranded DNA molecule contains 30% adenine. How many possible hydrogen bonds will be their between two strands of these DNA? How many strands make up an RNA polymer? If a stretch of DNA contains 808 nucleotides and 63 of them are cytosine, how many are thymine?
