Which cellular component will be found in the widest range of organisms in the sample?

ribosome

Which of the following conclusions about the radiolabeled amino acid is best supported by the results of the experiment?

Which of the following conclusions about the radiolabeled amino acid is best supported by the results of the experiment? It was mostly incorporated into proteins that regulate and manage metabolic reactions.

Which of the following best predicts what will happen to the lysosomal enzymes if the proteins that transport H H+ ions from the cytosol into the lysosome are damaged the lysosomal enzymes will not become active since there will be no active transport of H H+ ions?

Which of the following best predicts what will happen to the lysosomal enzymes if the proteins that transport H+ions from the cytosol into the lysosome are damaged? The lysosomal enzymes will not become active, since there will be no active transport of H+H+ ions.

Which statement correctly indicates the cell that is able to more efficiently?

Which statement correctly indicates the cell that is able to more efficiently exchange materials with the external environment and provides a correct explanation? The egg cell, because it has the smallest surface-to-volume ratio.

Which of the following is the most likely reason for the difference in leaf growth?

Which of the following is the most likely reason for the difference and leaf growth? The phosphorus- starved plant was unable to synthesize both the required NUCLEIC ACIDS and LIPIDS, limiting growth. Some amino acids are hydrophobic.

Which of the following describes a key difference between the 20 amino acids that are used to make proteins?

Which of the following describes a key difference among the 20 amino acids that are used to make proteins? Due to having nonpolar R-groups, 10 of the 20 amino acids are hydrophobic. Interactions between hydrophobic amino acids play an important role in determining protein structure and function.)

What are the 20 common amino acids?

Of these 20 amino acids, nine amino acids are essential:

Phenylalanine.
Valine.
Tryptophan.
Threonine.
Isoleucine.
Methionine.
Histidine.
Leucine.

What are the 20 r groups?

Structure of 20 standard amino acids

Alanine – ala – A.
Arginine – arg – R.
Asparagine – asn – N.
Aspartic acid – asp – D.
Cysteine – cys – C.
Glutamine – gln – Q.
Glutamic acid – glu – E.
Glycine – gly – G.

How many of the 20 commonly occurring amino acids are basic?

There are four of them, two basic amino acids, lysine (Lys) and arginine (Arg) with a positive charge at neutral pH, and two acidic, aspartate (Asp) and glutamate (Glu) carrying a negative charge at neutral pH.

What are the 24 amino acids?

Which amino acid is the most hydrophilic?

Arginine

Do all living things use the same 20 amino acids?

All life on Earth relies on a standard set of 20 molecules called amino acids to build the proteins that carry out life’s essential actions. All living creatures on this planet use the same 20 amino acids, even though there are hundreds available in nature.

Can we live without amino acids?

Diet Choices Food proteins lacking one or more of the essential amino acids can maintain life, but cannot support growth. These foods are known as incomplete proteins, or inadequate proteins. Some examples of food containing incomplete proteins are gelatin, corn, and most flours.

Why are there 64 codons and only 20 amino acids?

Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

Why are there no 64 amino acids?

64 combinations is clearly is overkill for just 20 amino acids. So most amino acids have multiple combinations of 3 nucleotides (called codons) which code for them – these are the synonymous codons. Glutamic acid and aspartic acid are chemically the same, differing only by a methylene group – get rid of one.

What is the 3 letter sequence that codes for an amino acid called?

codons

Can amino acids be repeated?

Amino acid repeats (AARs) are abundant in protein sequences. They have particular roles in protein function and evolution. Repeats with complex patterns mostly refer to the functional domain repeats, such as the well-known leucine-rich repeat and WD repeat, which are frequently involved in protein–protein interaction.

How many nucleotides are needed for three amino acids?

nine nucleotide
