What portion(s) of a whole grain is/are susceptible to spoilage?

1 answer:

6 0

Germ or embryo is the smallest portion of the grain, and the embryo for a future plant found at the base of the whole grain or kernel that accounts for 2.5 percent of the grains weight. It is very rich in fat, vitamins, minerals, incomplete protein and an excellent source of B vitamins and vitamin E which is collected and sold separately and makes the whole grains susceptible to spoilage.

Some regions of a polypeptide may coil or fold back on themselves. This is called _____, and the coils or folds are held in plac

zalisa [80]

Answer:

The options are

A. secondary structure ... hydrogen bonds

B. secondary structure ... peptide bonds

C. tertiary structure ... hydrogen bonds

D. primary structure ... covalent bonds

E. tertiary structure ... covalent bonds

THE CORRECT ANSWER IS A.

A. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups

-NH and C = O

At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.

The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.

miRNAs can control gene expression by what action?A. degrading proteins as soon as they are formedB. inhibiting the catalytic ac

levacccp [35]

Answer:

C) binding to mRNAs and degrading them or blocking their translation

Explanation:

<u>miRNAs:</u>

miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.

They silenced mRNA by the following processes:

(1) Cleavage of the mRNA strand into pieces,

(2) stopping mRNA from translation into proteins by ribosomes.

(3) Shortening of mRNA poly(A) tail and destabilizing it.

What are the differences between plant and animal cells

Zina [86]

Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.

Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase

Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
