Answer: C. 5 A C G U U A G G 3

Explanation:

A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. It is a short strands of RNA.

DNA and RNA are made up of different sequence of nucleotides.

Adenine (A), Cytosine (C), and Guanine (G) are nucleotides found in both DNA and RNA.

Only DNA contains Thymine (T) and only RNA contains Uracil (U).

Pairing in DNA:

A to T

G to C

Pairing in RNA:

A to U

G to C.

Therefore DNA and RNA can still be complementary to one another by substituting for thymine (T) and Uracil (U) where required.

Starting from the underlined T (T) of the template, we have 3 T G C A A T C C 5.

If we are to pair the complementary RNA nucleotides, we will have 5 A C G U U A G G 3

slavikrds [6]

Answer:

Sonic Hedgehog.

Explanation:

Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.

Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilitie
kaheart [24]

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:

1. dominant parent and recessive parent

2. heterozygous parents

Answer:

1. dominant parent and recessive parent:

dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.

so,

 L    L

l  Ll   Ll

l  Ll   Ll

so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.

2. heterozygous parents

In this case, parents have Ll genotype and gametes would be L and l for each parent so,

    L    l

L   LL  Ll

l    Ll    ll

In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:

3/4 = 75%

College varsity athletes have excellent knowledge of the major principles of sports nutrition. true or false
FromTheMoon [43]
The answer should be TRUE.
Sports nutrition is the study and practice of nutrition and diet to improve athletic performance. It focuses on the type and quantity of food and fluid that should be taken by athletes; foods that are rich in vitamins, minerals, supplements and organic substances such as carbohydrates, protein and fats. Ideally, college varsity players should very well know their sports nutrition because they are mature enough to know their own bodies and its needs more than anybody. Before, during and after tournaments, games or matches, it is but vital to know what your own body needs rather that consulting an expert every single time. However, if there is an increase demand of advice from experts, especially those who are frequent tournament players or those who wanted to do sports professionally, it is advisable to consult nutritionists or dietitian whom are experts in sports nutrition.
