James Dewey Watson is an American molecular biologist, geneticist and zoologist. In 1953, he co-authored with Francis Crick the academic paper proposing the double helix structure of the DNA molecule. Watson, Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". Watson earned degrees at the University of Chicago and Indiana
Answer:
It is the closest relative of Bombyx mandarina, the wild silk moth. The silkworm is the larva or caterpillar of a silk moth. It is an economically important insect, being a primary producer of silk.
"The differences in pre-mRNA splicing that results in an altered pattern of exon inclusion" is most likely to have contributed to this phenomenon.
<u>Option: C</u>
<u>Explanation:</u>
The expression of the eukaryotic gene requires several stages and can be regulated by several of them. Different genes are controlled at different locations and it is not unusual for a gene to be controlled at multiple steps, especially a significant or powerful one.
- In accessibility of Chromatin the chromatin structure includes DNA and can be regulated by its assembling proteins. More free or 'relaxed' chromatin allows a gene more transcriptible.
- For many genes transcription is a key regulatory point. Its factor protein sets bind to unique DNA sequences within or near to a gene and encourage or suppress its transcription into an RNA.
- It is possible to control the splicing, capping, and attaching a poly-A tail to an RNA molecule, and thus exit the nucleus. Specific mRNAs might be produced by alternative splicing from the same pre-mRNA.
Proteins are made up of a series of amino acids. Nucleic Acids (RNA and DNA) are made up of a series of nucleotides.
you really did not know this???
Answer: The nucleotide composition of the double-stranded DNA molecule from which it was transcribed is 30% T, 20% C, 24% G, and 26% A.
Explanation: RNA is transcribed from DNA in the process of transcription. The single stranded RNA is complementary to the DNA template strand. In DNA base pairing, adenine pairs with thymine while guanine pairs with cytosine, this means that in a double-stranded DNA molecule, the total number of adenine is equal to the number of thymine while the total number of guanine is equal to the total number of cytosine.
In RNA, adenine pairs with thymine, guanine pairs with cytosine while uracil pairs with adenine. This means that the total number of thymine on the DNA template strand is equal to the total number of adenine on the RNA strand, the total number of guanine on the DNA template strand is equal to the total number of cytosine on the RNA strand, the total number of adenine on the DNA template strand is equal to the total number of uracil on the RNA strand while the total number of cytosine on the DNA template strand is equal to the total number of guanine on the RNA strand.
RNA strand = DNA strand
30% A = 30% T
20% G = 20% C
24% C = 24% G
26% U = 26% A
