You assay cell surface oligosaccharides from a blood sample. After determining the composition of the oligosaccharides relative

to a reference monosaccharide, fucose, you conclude the donor is blood type B. What brought you to this conclusion?

Answer:

Here the fucose is linked to galactose by alpha1,2 glycosidic linkage.

Explanation:

Fucose is a deoxy sugar consist of 6 carbon atoms which means fucose is a hexose sugar.

   Fucose does not contain -OH group at C6 carbon that"s why it is termed as deoxy sugar.

     Fucose can link to both Nactylglucosame by alpha-1,6 glycosidic linkage and to galactose by alpha-1, glycosidic linkage  generates the H antigen.

   As donor is blood type B that means fucose is linked to galactoseof H antigen by alpha 1,2glycisidic linkage.

Which source will you analyze using active reading strategies?

Answer:

Answer:

The source I will analyze is stated below and is a secondary source that I found in the ShapiroLibrary.

Latkin, C., Sundberg, N., Littman, R., Katsikis, M., & Hagan, R. (1994). Feelings after the Fall: Former Rajneeshpuram Commune Members' Perceptions of andAffiliation with the Rajneeshee Movement. Sociology of Religion, 55(1), 65-73

I did a glance at the article and observed the title, the authors, and other descriptive information that was supplied. Five authors were had taken part in this article, and it was published about ten years after the situation at occurred. Jotting down a few ponits, and underlining key terms, I went through the material content and was able to relate to the actual world interrelatedness of the ancient occurrence that almost paralyzed communities in proximity to where I stayed in the 1980’s.

In summarizing this writing, I saw it to be enlightening as the authors explained in details the outcome of their study. They at first described what initially happend in Oregon when they Rajneeshees inhabited the region and dealt more on specific occurrence that was seen at that period. This information is likey the most useful of this writeup. However, they looked at 231 previous occupants of Rajneeshpuramabout 16-24 months when they have departed from Rancho Rajneesh. Those who answered to two different survey stated their persistent distress with the development, their behaviours, ideas or feelings in the direction of their experience while occupying Rajneeshpuram, their interaction with the Bhagwan, and other things that led to the tumble of the commune. In general, the survey findings showed that the precious occupants and followers of the Bhagwan, were always optimistic about their encounter at the period they inhabited the ranch. The best clarification of life at Rajneeshpuram coupled with the Rajneeshees' behaviours of life situations, the method by which they went away from the community, and the persistent aid and participation with the society as a reference set. The survey studies really gave information that upheld the reasons for the tumble of the compound.

If a DNA sequence is TTA, what would be the anticodon the tRNA would bring to the ribosome?
agasfer [191]

Answer:

So the central dogma of molecular biology describes the journey from DNA to protein product:

DNA --transcription--> mRNA --translation--> Protein

Assuming the DNA sequence provided is the template strand (rather than the complimentary coding strand), we start by transcribing the sequence into mRNA starting on the 3' end of the DNA towards the 5' end (which would build the mRNA 5' to 3'). This process involves the enzyme "RNA polymerase," which can only add nucleotides to the 3' end of the mRNA, just like how DNA polymerase can only synthesize DNA in the 5' to 3' direction. The RNA polymerase will bind to the template DNA strand and synthesize the complimentary mRNA, substituting uracil for thymine (since RNA does not contain thymine like DNA).

In terms of transcribing the sequence given to you, we'll have to work backwards + flip it around to get the 5' to 3' mRNA since the DNA is given 5' to 3' rather than 3' to 5'. Due to the length and the fact that we'll have to use triplets in translation anyways, it can help to break the sequence into triplet codons now.

5’-AAG | TTA | ATG | AGA | AAT | CGA | CAT | GGG | GCG | CCG | AAA | GTA | TAA | CCG | TCT | TAG | AAT | AGC-3’

We can then cross out each codon as we transcribe it and flip the sequence to be 5'-3' mRNA:

mRNA: 5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'

Normally, mRNA sequences start with "AUG" which is the start codon (and codes for Methionine), but I'll assume this is just for practice translating + transcribing in general. There's also a stop codon before the end but I'll assume the same again.

Translation involves three main steps - initiation, elongation, and termination. Initiation involves the translation ribosome assembling around the mRNA starting at the 5' end start codon, and tRNA carrying an amino acid binding to the complimentary section of the mRNA. As each tRNA attaches and the ribosome moves along the mRNA, the amino acids on each tRNA are bonded into a longer and longer peptide chain and the now amino acid-less tRNA are ejected (elongation). Termination occurs when a stop codon is reached, the ribosome will end elongation and help fold the protein into its final structure.

To translate the mRNA sequence here we'll need an amino acid/mRNA codon chart. I don't believe I can attach an image here, but looking up those exact words should yield the right results in images.

5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'

Ala - Ile - Leu - Arg - Arg - Leu - Tyr - Phe - Arg - Arg - Pro - Met - Ser - Ile - Ser - His - STOP - Leu

Amino acids are often abbreviated into three letters (Ala = alanine, Met = methionine, etc), and sometimes are abbreviated as single letters, though I've only seen that for sequencing databases.

In terms of locations for each of these processes, transcription occurs in the nucleus for eukaryotes and translation in the ribosomes/cytoplasm.
