Answer:

The dew point is always lower than (or equal to) the air temperature. If the air temperature cools to the dew point, or if the dew point rises to equal the air temperature, then dew, fog or clouds begin to form. At this point where the dew point temperature equals the air temperature, the relative humidity is 100%.

The dna polymerase extends the primers into a new dna strand by.

Yuki888 [10]

Answer:

adding nucleotides one by one

Explanation:

A typical primer is about five to ten nucleotides long. The primer primes DNA synthesis, i.e., gets it started. Once the RNA primer is in place, DNA polymerase "extends" it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand.

-Huntington's

Juliette [100K]

A pedigree is the representation of family history. 1) I.1, II.2, II.3, II.7, III.3 / 2) Dominant / 3) Six / 4) 2 girls, 1 affected / 5) niece-uncle and grandma-grandson

---------------------------

Huntington's disease is an autosomal dominant affection.

It is expressed by heterozygous individuals, meaning that only one copy of the altered gene is enough to express the phenotype.

The mutated gene is the dominant one.

I will answer these questions according to the attached pedigree.

A pedigree is the representation of family history through which it is possible to follow the inheritance pattern of certain traits.

To correctly interpret a pedigree, we need to consider that,

Squares represent males or men,
Circles represent females or women.

Solid figures represent affected individuals,
Empty figures represent normal individuals.

Roman numbers indicate generations.

Individuals can be identified using numbers, genotypes, names, or others.

1. Which members of the family above are afflicted with Huntington's Disease?

I.1 ⇒ Man of the first generation

II.2, II.3, II.7 ⇒ Two women and one man of the second generation

III.3 ⇒ One woman of the third generation.

2. There are no carriers for Huntington's Disease- you either have it or you don't. With this in mind, is Huntington's disease caused by a dominant or recessive trait?

Huntington's disease is caused by a dominant allele. So a single altered gene is enough to express the affection.

3. How many children did individuals l-1 and 1-2 have?

They had six children.
