A strand of DNA that is 36 nucleotides long codes for how many amino acids?
Margarita [4]

Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons <em>first</em>.

36 \ ncltd \ \frac{1 \ codon}{3 \ ncltd} = 12 \ codon\\12 \ codon - 1 \ codon \  = 11 \ codon\\11 \ codons\ \frac{1 A.A.}{1 \ codon}  = 11 \ A. A.

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,

Which of these organisms contains no specialized cells?
Gemiola [76]

Answer:

Option C, Paramecium

Explanation:

Complete question

Which of these organisms contains no  specialized cells?

a. Sea anemone

b. Jellyfish

c. Paramecium

d. Sponge

Solution -

Paramecium consists of only cell and hence the chance of it having specialized cells is nill. Its size is somewhere around between 50 to 300 micrometer. It belongs to kingdom Protista and is a single celled eukaryote. While on the other hand sea anemone, sponge and jelly fishes are multicellular with various special structures such as tentacles, cilia , flagella. Hence, these three must be having specialized cell.

Which of the following experimental data would suggest the presence of a transmembrane protein? The primary sequence contains st
Zina [86]

Answer:

All of the other answer choices suggest the presence of a multipass transmembrane protein.

Explanation:

The primary sequence contains stretches of polar and nonpolar amino acids, suggesting an amphipathic design.

This one could be, because of the presence of polar an nonpolar aminoacids. The phospholipids membrane have the same construction.

The protein has windows of the primary sequence with positive hydropathy values separated by windows of the primary sequence with negative hydropathy values.

The same here, having pieces of positive and negative hidropathy can be a sign of transmembrane protein.

The protein isolates with the membrane fraction of the cell rather than the cytoplasmic fraction of the cell.

This is discribing you a transmembrane protein
