What does the nucleus carry

1 answer:

3 0

The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. Each human cell contains roughly two meters of DNA.

Assume that endogenous acid production is 40 meq during a 12-hr period. A urine sample collected during this time contains 30 mm

MrMuchimi

Answer:

Thus, the Quantity of $HCo_{3}^{-}$ Present in urine sample in 24 hours is 35mmol

Explanation:

Acid Production in 12 hours = 40 meq

For, 24 hours = 40 meq × 2

Acid Production in 24 hours = 80 meq

Urine sample for $NH4^{+}$ = 30mmol

$HCo_{3}^{-}$ Present in Urine Sample in 24 hours

= Acid Production - Urine sample for $NH4^{+}$ - Titratable Acid

= 80 - 30 - 15

= 50 - 15

= 35mmol

$HCo_{3}^{-}$ Present in urine sample in 24 hours is 35mmol

How are bioclastic rocks formed? SOMEONE PLEASE HELP ME ILL GIVE YOU BRAINLIST ANSWER !!!

algol13

Bioclastic sedimentary rocks form when fragments from previously living material, or material produced by a living thing, is compacted to form a rock. How was coal formed? Coal is formed from the compaction of partially decayed ancient plant material

Which functional area of monique's cerebral cortex is most likely to be impacted by the tumor?

Daniel [21]

Visual association area is functional area of Monique's cerebral cortex is most likely to be impacted by the tumor. Association cortex is the cerebral cortex outside the primary areas. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation, for which primary sensory areas appear to be necessary.

Need a hypothesis for “How are proteins built from RNA”

Dima020 [189]

Hi!

Hypothesis:

Proteins are built from the translation of messenger RNA (mRNA) molecules

RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).

RNA is generated through transcription of the DNA molecule, resulting in a complementary molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA (complementary with U instead of T)

<h3>From RNA to Protein</h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon UCA, the tRNA will allocate a Serine residue.

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.

Hope this helps!
