How many different mRNA molecules can specify the amino acid sequence, Met-Tyr-Arg-Thr? Which amino acid(s) have (a) the fewest number of codons? (b) the greatest number of codons? How many nucleotides are needed to identify one amino acid?
Surprisingly, the number of human genes seems to be less than a factor of two greater than that of many much simpler organisms, such as the roundworm and the fruit fly -- see table showing number of genes for different organisms. How many genes do other organisms have? Humans though have ...
How many double-stranded DNA molecules are in one chromosome? How many hydrogen bonds are between adenine and thymine? How many amino acids are coded for by the DNA? How many DNA molecules make up an unreplicated chromosome? How many different bases can be found in a molecule of DNA?
How many amino acids are involved in protein synthesis? How many nonessential amino acids are produced in the body? What do all amino acids have in common? If each nucleotide codes for a specific amino acid, how many different amino acids could be used to produce proteins?
How many proteins are there in humans? 基因數目的計算一向困難重重。蛋白質可能以不同的方式剪輯、並且以各種功能基來修飾,這些使得目前基因數量的計算窒礙難行。 It has been hard enough counting genes. Proteins can be spliced in different ways and decorated with numerous functional groups...
The term “vegan protein” refers to plant sources that are rich in proteins.Proteinsare one of the essential macronutrients humans need and these complex molecules play many crucial roles in the body including most of the work required for the regulation, function, and regulation of the tissues...
Protein coding features can emerge de novo in non coding transcripts, resulting in emergence of new protein coding genes. Studies across many species show that a large fraction of evolutionarily novel non-coding RNAs have an antisense overlap with protei
The WHO team reported that the virus was most likely of animal origin, which was then passed on to humans, disagreeing with suggestions that it had escaped from a virology laboratory in Wuhan (WHO 2020a, b). Nevertheless, there is still considerable dispute as to the source of the virus;...
How many codons and how many DNA bases do you have the part of the gene that encodes the enzyme uricase? Codons: Codons are triplets of nucleotides which code for one amino acid. There are also codons which signal ribosome to start translation (start ...
How is bacterial DNA replication different from eukaryotic DNA replication? How many nucleotides define one codon for one amino acid? What does RNA primase do in DNA replication? How many strands of DNA do humans have? How can DNA replication be modeled?
