What would be the consequence for DNA synthesis if DNA ligase were defective?
Lagging strand synthesis would be incomplete; leading strand synthesis would be unaffected.
What are leading strands?
Leading strands are one of the two newly synthesized DNA strands during DNA replication. They are synthesized in a continuous manner in the 5' to 3' direction, following the replication fork. The leading strand is synthesized in the same direction as the replication fork is moving, allowing for continuous synthesis.
Describe the major steps of protein synthesis on the ribosome?
during initiation and elongation, the ribosomes attaches to a specific site in the codon, AUG. It moves along the A site as trna comes to the mrna strand and delivers amino acids forming the polypeptide chain, based on the amino acids formed.
What is important features in synthesis phase?
Synthesis phase or "S phase" occurs during the interphase of a cell cycle between the G1 and G2 stages. During synthesis phase, DNA molecules "unzip" and each old strand attracts free nucleotides forming complementary new strands, leaving two strands of DNA identical to the original strand of DNA.
Does dna ligase help assemble the leading strand?
Not in general replication as the leading strand is replicated straight away. The lagging strand is replicated in pieces that need ligase to affix them, one to the other. However, in a replication bubble, when a lagging strand runs into a leading strand, and later the primers are replaced, ligase is still needed. Therefore, technically, the leading strand does need the ligase once.

What is the DNA strand that is synthesized continuously during DNA replication?
leading strand
Does helicase catalyze the elongation of a new DNA strand?
No.

Which strand in dna synthesis is created in pieces?
The lagging strand

Synthesis of M-RNA strand from DNA strand inside nucleus?
Transcription
There is a y shaped replication fork on each side of each replication bubble what are the sides of the replication fork called?
One is known as the Leading strand, and the other is known as the Lagging strand.
Where does ssb protein bind on lagging strand or on leading strand?
ssb protein bind to the lagging strand as leading strand is invovled in dna replication and lagging strand is invovled in okazaki fragment formation
Why RNA primers are needed during DNA replication and what is their fate?
DNA polymerase cannot begin the synthesis of new DNA.To synthesis a new strand of DNA ,RNA primer is required.The complementary RNA nucleotides,that are added opposite to the single strand of parent DNA are the RNA primer.
