How many strands make up a DNA structure? DNA Structure: DNA is a long complex molecule that's composed of a series of four different nucleotides, adenine, thymine, guanine, and cytosine. The sequence of nucleotides in the DNA strand determines the sequence of nucleotides in the mRNA strands...
A DNA sequence is 1500 nucleotides long. Answer the following questions: A) How many amino acids does this sequence code for? B) How many mRNA strands does this sequence code for? C) How many proteins does this sequence code for? D) Would it be mo...
Historically, antibiotics have been used to preventS. suiscases, but this practice is nowadays prohibited in many countries. Also, vaccination is used to prevent infection, but its efficacy is limited. Only bacterins are applied in the field for immunization of piglets or sows. Bacterins are ...
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 bases are in a codon? How many strands make up an RNA polymer? Define essential amino acids How many base pairs are in 18S ribosomal RNA? How many single-stranded DNA viruses are there? How many oncogenes are there in retroviruses?

The purpose of the salt is to help the strawberry DNA remain undissolved in water. Once the alcohol is added to the strawberry pulp, the DNA strands rise to the top and bind together. This is where you can see them together in one long, clear strand. It’s fascinating to see the ...
Viral core: Inside the envelope is the core, which contains 2,000 copies of the viral protein p24. These proteins surround two single strands of HIV RNA, each containing a copy of the virus's nine genes. Three of these genes — gag, pol and env — contain information needed to make st...
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...
in these assays the protein of interest is purified after it has been expressed either heterologously or constitutively from different synonymous messenger RNA (mRNA) variants. A synonymous mRNA variant is an mRNA molecule where one or more codons have been replaced by a synonymous codon, which doe...
