Answer:

what are tRNA anticodons?

anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries. DNA - the molecule that stores and encodes an organism's genetic information.

How do you find the anticodon on a tRNA?

An anticodon is found at one end of a transfer RNA (tRNA) molecule. During protein synthesis, each time an amino acid is added to the growing protein, a tRNA forms base pairs with its complementary sequence on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein.

Answer:

By using sequence information from covalently attached nucleotides.

Explanation:

TRNA presents an anticodon sequence to required sites as a physical bridge with elongation factors (proteins) to form a connection between mRNA and ribosome and encode amino acids to ultimately form specific protein structure. tRNA carries out this activity by using sequence information from covalently attached nucleotides.

Answer:

B. Directional selection

Explanation:

When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.

Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is $\frac{1}{2}$ curly tails, $\frac{1}{4}$ straight tales, $\frac{1}{4}$ tailless

Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity

Explanation:

Hydroelectric power is generated from free falling water through a river channel.

The flow of water at a high speed creates water current and the kinetic energy of the water movement spins turbine attached with a generator. This produces a rotating energy which spins the generator and the coil inside.

The magnetic spinning of coiled wire inside the generator produces electric current which is then stored and transmitted through electric power grid lines to supply electric current.

Describe the ways Sulfur can get into the atmosphere.

Norma-Jean [14]

Answer:

It enters the atmosphere through both natural and human sources. Natural resources can be for instance volcanic eruptions, bacterial processes, evaporation from water, or decaying organisms. ... Sulfur dioxide may also react with water to produce sulfuric acid (H2SO4).
