Left thumb over right is dominant, and is represented with a capital C. Right thumb over left is recessive, and is represented with a lowercase c.What would be the genotype of a person who naturally crosses his right thumb over his left when folding his hands together?

A) cc

B) Cc

C) CC or cc

D) CC or Cc

Answers

Answer 1

Answer:

Answer: Option A) cc

Explanation:

For a given gene, there are 2 or more alternative forms present, and they are known as alleles.
The alleles are of two types - dominant and recessive.
The dominant allele is the one which expresses itself in both heterozygous and homozygous condition in the phenotype.
The recessive allele is the one which is only able to express itself in homozygous condition.
Since, the right thumb over left allele c is recessive, the person who crosses right thumb over left must be a homozygote, and hence his genotype should be cc.

Density-dependent inhibition is a phenomenon in which crowded cells stop dividing at some optimal density and location. This phenomenon involves the binding of a cell-surface protein to its counterpart on an adjoining cell's surface. A growth-inhibiting signal is sent to both cells, preventing them from dividing. Certain external physical factors can affect this inhibition mechanism. True or false?

In 1953, Miller and Urey constructed an experiment that attempted to mimic the conditions leading to the formation of biomolecules on early Earth.Part A: Construct a hypothesis statement that Miller and Urey might have made prior to conducting their experiment. Use an “if, then” format to write your statement. (1 point)

Part B: Describe in detail their experiment. Include what they used to simulate the conditions of early Earth, and what their results were. (3 points)

Answers

Answer:

A// If early conditions of primeval earth had ammonia, methane, hydrogen in its atmosphere, then it is possible that amino acids such as glycine, α-alanine, and β-alanine may have been spontaneously formed from chemical reactions spurred by energy from lightning.

Their hypothesis was that the early conditions of primeval earth favored the spontaneous formation of organic molecules, from inorganic precursors, that may have been the origin of life. This theory is called abiogenesis.

B//Miller Urey put methane, ammonia, hydrogen gases in a glass flask and a pool of water at the bottom of the glass flask. The flask was heated moderately to simulate the hot conditions then. Sparks were also occasionally induced in the flask to mimic lighting. The flask was then cooled slowly to simulate cooling of earth over time.After one day, they found the presence of some amino acids (glycine, α-alanine and β-alanine) was discovered in the water in the flask

Explanation:

Imagine that you are studying the control of β-globin gene expression in immature red blood cells (mature red blood cells contain β-globin protein but lack a nucleus and therefore the β-globin gene). If you deleted a sequence of DNA outside the protein-coding region of the β-globin gene and found that this increased the rate of transcription, the deleted sequence likely functions as a(n) _____. a. enhancer b. promoter-proximal c. element promoter d. silencer e. any of the above

Answers

Answer:

d. silencer

Explanation:

Based on the information provided within the question it can be said that the deleted sequence most likely functions as a silencer. This term refers to a DNA sequence that is located thousands of base pairs away from the gene that they actually control. In this situation, seeing as the DNA sequence that was found outside the protein coding region actually affected the rate of transcription when it was deleted then it is considered a silencer.
