In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrin
meriva

Assuming the genes are not linked nor interacting with each other, the expected number of long stemmed plants with purple flowers, producing wrinkled peas, L-P-rr, is 288.

<h3>Available data</h3>

  • long stems are dominant to short stems
  • purple flowers are dominant to white,
  • round peas are dominant to wrinkled

  • Each trait is determined by a single, different gene.

  • A heter0zyg0us plant is self-crossed
  • F1) 2,048 descendants

Let us name te alleles as follows

  • L ⇒ Long stem
  • l ⇒ Short stem
  • P ⇒ Purple flowers
  • p ⇒ white flowers
  • R ⇒ Round peas
  • r ⇒ wrinkled peas

Cross) heter0zyg0us plant is self-crossed

Parental) LlPpRr

Gametes) LPR, LPr, LpR, Lpr, lPR, lPr, lpR, lpr

Assuming that these genes are not linked nor interacting with each other, to make the calcs easier we will make crosses considering each gene separately.

  • Stems

Parental) Ll  x  Ll

F1) 1/4 LL, 2/4 Ll, 1/4 ll

     <u>3/4 long stem,</u> 1/4 short stem

  • Flower color

Parental) Pp  x  Pp

F1) 1/4 PP, 2/4 Pp, 1/4 pp

     <u>3/4 purple flowers</u>, 1/4 white flowers

  • Peas

Parental) Rr  x  Rr

F1) 1/4 RR, 2/4 Rr, 1/4 rr

     3/4 round peas, <u>1/4 wrinkled peas</u>

Now, we will get the proportion of individuals with long stems, purple flowers, producing wrinkled peas, L-P-rr

<u><em>Note</em></u><em>: The symbol - is representing either a dominant or a recessive allele.</em>

From the crosses, we know that

  • 3/4 are long stemmed,
  • 3/4 have purple flowers, and
  • 1/4 have wrinkled peas.

To get the proportion of individuals expressing all these traits together, we just need to multiply these values.

3/4 L- x 3/4 P- x 1/4 rr =<u> 9/64 L-P-rr</u>

Knowing that  the total number of plants is 2,048 and that there are 64 possible gametes combinations from this cross, we will use the proportion 9/64 to get the number of plants with these traits.

64 ------------- 2,048 plants

9 -------------- X = (9 x 2048) / 64 = 288 plants.

<em>We expect to find 288 long stemmed plants with purple flowers, producing wrinkled peas.</em>

Which of the following requires eIFs for initiation? Which of the following requires eIFs for initiation? eukaryotic translation
andre [41]

Answer:

Eukaryotic translation.

Explanation:

Translation is the process of the formation of the proteins from the RNA molecules with the help of different enzymes and proteins. Translation is quite different in case of prokaryotes and eukaryotes.

The initiation in case of eukaryotes requires different enzymes and translation factors. eIFs are the initiation factors that contains proteins and required for the initiation of eukaryotes translation. eIF1 and eIF1A are the proteins binds with the 40'S ribosome subunit of eukaryotes.

Thus, the correct answer is option (1).
