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.

You observe a tissue under the microscope and see intercalated discs between adjacent cells. which tissue are you observing

Monica [59]

The correct answer is a muscle tissue, more precisely cardiac muscle tissue. <span>Cardiac muscle tissue consists of individual cardiomyocytes (heart muscle cells) which are connected by intercalated discs to work as a single functional organ. The function of intercalated discs is to support synchronized contraction of cardiac muscle.</span>

Answer:

A) habitat fragmentation makes it easier for cowbird parasitism to occur

Explanation:

It is a situation where by there is transformation of a large habitat into smaller patches with smaller total area secluded from one another by a habitat different from the initial one.

Habitat fragmentation can be caused due geological processes which distort the physical environment. It is also casued by human activities which could lead to loss or extinction of certain species.

Habitat fragmentation could possibly lead to loss of habitat and biodiversity.

The functional and structural unit of the kidneys is the:_______.

serg [7]

Answer: c. nephron

Explanation: The nephron is the functional unit of the kidney, which actively filters blood and generates urine. The nephron is made of the renal corpuscle and renal tubule. Cortical nephrons are located within the renal cortex, whilst juxtamedullary nephrons are observed inside the renal cortex near the renal medulla.
