How many strands make up an RNA polymer? What acts as the template in DNA replication? What are primers in DNA replication? How many strands of DNA are found in somatic cells? Where would the enzyme topoisomerase attach during DNA replication?
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?
and make up many body chemicals including enzymes and hormones. The genetic code for making proteins contained in the DNA directs the synthesis of a version of RNA called messenger RNA, or mRNA, which transports these instructions out of the nucleus of the cell (where DNA resides) into the ...
RNA polymerase binds to the DNA strand at the promoter, unlinks the two strands of DNA and then makes a complementary copy of one of the DNA strands into an RNA strand. RNA, or ribonucleic acid, is very similar to DNA except that it is happy to live in a single-stranded state (as ...
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...
The presence of restriction enzyme buffer is important while heating as this will prevent small DNA fragments from melting into single-strands. Denaturation of restriction enzyme Many restriction enzymes can be inactivated by heat. Also, avoid vortexing dilutions or reactions containing restriction ...
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 transcriptome, however, is a busy place, and there are lots of different species of RNA. Messenger RNA (mRNA) codes for proteins, whereas non-coding RNA (ncRNA) serves other roles, many of which are unknown. There is growing evidence that both small ncRNAs, such as microRNAs, and lon...
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 ...
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 ...
