Answer:

There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.

Which valves produce the second heart sound when they snap shut?

Taya2010 [7]

Answer: D) Pulmonary and aortic valves.

Explanation
There are two main heartbeats from a healthy heart.

The first beat is called the S1 or the lub, and it occurs when the atrioventricular valves (comprising the mitral and tricuspid valves) close.

The second beat is called the S2 or the dub, and it occurs when the semilunar valves (comprising the aortic and pulmonary valves) close.

Listening for heart beats is an essential part of cardiac auscultation.

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???

Tomtit [17]

Answer:

Four (4) cells

Explanation:

Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).

For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.

Template DNA 5' GATTCAGAGA 3'

Complemntary strand 3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

codes of mRNA GAU, UCA, UAG

Explanation:

5' GATTCAGAGA 3' is the example of DNA strand having the sequence.

The DNA strand is leading strand and is in 5' to 3' direction

the complementary DNA strand is formed in 3'to 5' direction as the strand of 5' to 3' acts as a tempelate for complementary strand.

During replication which is semiconservative a new template is formed by adding the nucleotides to the growing strand.

DNA synthesis always takes place in 5' to 3' direction.

5' GATTCAGAGA 3'

3' CTAAGTCTCT 5' Complemntary strand

Transcription is a process in which DNA sequence is transcribed into mRNA which carries codes for amino acids.

The 5' to 3' strand is called sense strand

3' to 5' strand is called antisense strand. mRNA is transcribed from antisense strand and is a copy of sense strand.

so the transcribed DNA strand as mRNA will be shown as:

3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

GAU codes for = Aspartate

UCA codes for = serine

GAG code for = glutamate (when due to mutation GAA will become GAG)

A will not code as it is not in triplets.
