What is semi-conservative replication

Answers

Semi-conservative replication of DNA is when the parent strand of DNA splits into two single strand. Each single strand of parent DNA serves as a template for the production of the new, complementary DNA strand.

Semi-conservative entails conserving one “older” parent piece of DNA and using it with a new complementary strand.

In leopards, being shy (S) is dominant to being sassy (s), and being timely (T) is dominant to being tardy (t).
A female leopard that is
heterozygous for both the S and I trait mates with a male leopard that is also
heterozygous for both traits. Both the S and I traits assort independently from one another.
What is the probability that they will have an offspring that is sassy and timely?

Answers

The probability that the leopards will have an offspring that is sassy and timely is 3/16

This question involves two different genes. The allele for being shy (S) is dominant to the allele for being sassy (s) in the first gene while the allele for being timely (T) is dominant to being tardy (t).

According to this question, A female leopard that is heterozygous for both the S and T traits i.e. SsTt mates with a male leopard that is also heterozygous for both traits i.e. SsTt

The two heterozygous leopards (SsTt) will produce the following gametes: ST, St, sT, and st

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

S_T_ = shy, timely (9)S_tt = shy, tardy (3)ssT_ = sassy, timely (3)sstt = sassy, tardy (1)

According to this question, the probability that the two leopards will have an offspring that is sassy and timely is 3/16.

textWhere are nonpolar amino acids of a protein more likely to be found? Check all that apply

Answers

Answer:

At the interior side.

Explanation:

Nonpolar amino acids of a protein more likely to be found at the interior side of the  soluble proteins where they are far from the water because water is a polar molecule and only polar amino acids of protein can interact with the water so that's why the polar amino acids are present on the surface of  soluble proteins and the nonpolar amino acids of a protein are present at the interior side of the soluble proteins due to its nonpolar nature.

Convoluta worms hatch in early spring. They crawl about in the mud feeding on algae, which find their way into the skin of the worms. There they prosper as they worms feed on the sun-warmed surface mud.

The worms become greener and greener as they mature. Gradually their mouths seal shut, leaving only an internal garden of algae to provide them with food. As winter approaches, their food supply is exhausted, and the worms grow pale again. They lay their eggs in the mud just before they starve to death.

Loss-of-function mutations in the coding region of the homologous gene in humans result in loss of hair, teeth, and sweat glands, as in the toothless men of Sind (India). What does this suggest about hair, teeth, and sweat glands in humans? Select the two correct answers. a) The phenotype of loss of Eda function in humans indicates that Eda has been co-opted by evolution to control different aspects of development, as it does in sticklebacks. b) The phenotype of loss of Eda function in humans indicates that human Eda protein and stickleback fish Eda protein contain structurally similar DNA-binding domains. c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types. d) The phenotype of loss of Eda function in humans indicates that human hair and teeth might be homologous to stickleback fish bony plates. e) The phenotype of loss of Eda function in humans indicates that hair, teeth, and sweat glands are homologous structures.

Answers

Answer:

c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types.

e) The phenotype of loss of Eda function in humans indicates that hair, teeth, and sweat glands are homologous structures.

Loss-of-function mutations in the coding region of the homologous gene in humans result in loss of hair, teeth, and sweat glands, as in the toothless men of Sind (India). This suggestion in their hair, teeth, and sweat glands indicates that a)  The phenotype of loss of Eda function in humans indicates that Eda has been co-opted by evolution to control different aspects of development, as it does in sticklebacks. c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types.

Ectodysplasm A (EDA) is known as a transmembrane protein in the human body that is responsible for the development of ectodermal tissues of the human skin and teeth.

 

The cooption of Eda with evolution is likely to bring about changes in the development which results in phenotypic loss of Eda. Various genetic studies reveal the orthologous nature of the Eda gene, indicating a comparable method of development, and Eda plays a part in the control of embryonic ectoderm growth, which is essential for the formation of teeth, hair, as well as the sweat gland.

Therefore, we can conclude that Option A and C are both correct from the following options.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X

objective by raising the oil objective a little to avoid the damage to objective lens. Critique his

technique. (1 pt.)

Answers

Answer:

See the answer below

Explanation:

In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.

For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.
