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.

if the velocity of a vehicle starting from rest reaches 5m/2s in 2seconds, is the velocity of the vehicle uniform ?explain.

Vanyuwa [196]

Explanation:

Avg speed × total times = total distance

20×25=500

Since acceleration in the 1st interval is same as deceleration in the 3rd interval and deceleration is from the same velocity achieved after acceleration, t
