Using the genetic code below, what protein sequence does the rna sequence cuagcucgauaucuc code for?

1 answer:

4 0

If CUAGCUCGAUAUCUC is a mRNA sequence then the codes are:
CUA - Leucine
GCU - Alanine
CGA - Arginine
UAU - Tyrosine
CUC – Leucine
<span>This means that the protein synthesized during the translation is going to have a sequence LeuAlaArgTyrLeu.</span>

Mendel’s law of independent assortment says that the inheritance of one trait is not influenced by inheritance of another trait.

Svetradugi [14.3K]

Answer:

In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.

Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules

timurjin [86]

Answer and Explanation:

a. form the antigen-binding site ⇒ both chains

The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.

b. contain multiple variable domains ⇒ none

Both chains - light and heavy - contain <u>only one</u> variable domain (VL and VH).

c. are found in the Fab fragment ⇒ both chains

The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.

d. are found in the FC fragment ⇒ heavy chains

The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.

e. contain only one constant domain ⇒ light chains

Each light chain contains one variable domain (VL) and one constant domain (CL).

f. contain multiple constant domains ⇒ heavy chains

Each heavy chain contains three constant domains: CH¹, CH² and CH³.

g. contain only one variable domain ⇒ both chains

Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

In this lab, the three flocks of birds changed in numbers between generation 1 and generation 3. Why? Check all reasons. The amo

anyanavicka [17]

Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would

- The amount of food increased or decreased

- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa

Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.

When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling

guapka [62]

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

In water molecules hydrogen bonds provides a special dipole - dipole attraction.
Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
This makes the molecule of water polar.
By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.

Indicate whether each statement is true or false. 1. Rod cells are depolarized in the dark. (Click to select) 2. Glutamate binds

faltersainse [42]

Answer:

The correct answer is - 1. true, 2. true, 3. false, and 4. true.

Explanation:

1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.

2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.

3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.

4. when the light reaction takes place retinal converted to opsin
